Black Dragon Slayer Magic

Black Dragon Slayer Magic (黒の滅竜魔法, Koku no Metsuryū Mahō), also referred to as Darkness Dragon Slayer Magic (冥の滅竜魔法 Yami no Metsuryū Mahō), and  (影の滅竜魔法 Ei no Metsuryū Mahō) is a Caster Magic, Lost Magic, Slayer Magic, and lastly as well as most obviously, a Dragon Slayer Magic which is focused upon the transformation of the physiology of the caster's body into a dragon, which are extremely powerful and flight-capable legendary creatures that are a strange mixture between serpentine, reptilian and avian traits that live in ; resulting in Water Dragon Slayer Magic revolving around the generation, manipulation, and absorption as well as consumption of the element of darkness, which is the polar opposite to brightness, the result of the condition of a very small amount or even an absence of visible light; beings are incapable of distinguishing colours in conditions of either high brightness or darkness, and in conditions of insufficient light, perception is achromatic and ultimately, black; not only this, Black Dragon Slayer Magic encompasses shadows, which is a space where light from a light source is blocked by an opaque object, occupying all of the three-dimensional volume behind an object with light in front of it; indeed, Black Dragon Slayer Magic doesn't only manipulate anything that's classified as "dark energy", but it encompasses the "concept", which are a generalization or abstraction from experience or the result of a transformation of existing ideas, the concept being instantiated by all of its actual or potential instances, whether these are things in the real world or other ideas that can be classifed as part of the dark arts, allowing Black Dragon Slayer Magic to transcend most, if not all other umbrakinetic-type magics.

Black Dragon Slayer Magic is touted as one of the very first forms of Dragon Slayer Magic in the Sun Trilogy timeline alongside Photon Dragon Slayer Magic of the Dragon of Dragons, being developed by the Unbreakable Dark soon after Magic came into being on Earth Land through the opposing emotions from the Old World contacting the dormant Ley lines, resulting in an enormous surge of magical energy that washed over the world that induced a rapid evolution of the animal kingdom, blending their Deoxyribonucleic acids with that of the despair energy created by the Hellions to mutate their existences into dragonkind, with the strongest of the lot developing this magic quickly, before she instructed others of her kind to do the same, leading to the boon of Dragon Slayer Magic in the present time. Black Dragon Slayer Magic is utilized by Black Dragon, Níðhöggr. It is one of the few constants about Níðhöggr, remaining equipped within his Factor of the Dragon throughout his many reincarnations and clones, appearing alongside him during Daybreak Side-Story: Dragorigin in his original form, Daybreak S2 as Níðhöggr Replicant, and in Fairy Tail: Dawn's Ragnarok Arc as Níðhöggr SIN.

Description
As briefly mentioned above, Dragon Slayer Magic is a Caster Magic, Lost Magic, and last but not least, a Slayer Magic that allows its users to transform the physiology of their body into those of a dragon, a species of legendary creatures whom are oftentimes regarded as the strongest of all monsters with immeasurable power and intelligence dwelling within their bodies – dragons can be said to be less of an organic creature themselves but rather, an embodiment of the greatest power of all, and as such, these beings are revered and feared by all whom are knowledgeable of their existence, the mere mention of them causing shockwaves that radiate throughout the lands, magicians of all ranks and walks of life quivering at their name. More importantly, as "ultimate power made physical", they would need an "ultimate magic" to suit their very nature as power manifested in the mortal plane of existence; something that would be far above most magicians in the era that they made their mark on mankind. They could be thought of as "Elemental Magic made manifest and brought to its absolute zenith", though while a personification of the strongest power imaginable; the chains known as a "mortal body" that bind them to the dimension referred as do not hinder their performance in battle in the slightest – in fact, their mortality and physical form allow them to utilize their unique Magic Origin which is referred to as the Factor of the Dragon (竜の因子, Ryū no Inshi); indeed, the dragon's origin produces a unique magical power that transcends what could be achieved by normal humans. Normally, a magician's body could be considered a machine which created magical energy, a Dragon's magic origin acts as living power plant which created magical energy, serving the purpose of an enormous magic core with tremendous capacity that generates all sorts of elemental energy that's independent from their body through the simple act of breathing, capable of serving as a power source to power countless appliances – all this works in conjunction alongside the perks that their biology normally gives them; and through application of magical manipulation, grants them the ability to reinforce the sheer power of their own body with their signature element which is assigned to them as birth; generating limitless quantities of their element with an absolute dominance over said element, bestowing upon the wielder of Dragon Slayer Magic fearsome power in the heat of combat. In this case, as Níðhöggr is the Black Dragon and possesses a burning hatred of any race other than dragonkind, Black Dragon Slayer Magic will never be passed on to another user, unless it was from a Ryū no Lacrima (, Ryū no Rakurima lit. Magic Crystal of Dragons); an rare and extremely expensive Lacrima which is a magic crystalline substance found in both and  that gives individuals artificial Dragon Slayer Magic when implanted, thus making any potential inheritor a Second Generation Dragon Slayer Magic (二世滅竜魔法, Nisei Metsuryū Mahō) by default.

In the case of the Black Dragon Slayer Magic when used by a dragon, the Unbreakable Dark takes blatant advantage of the fact that his mortality and physical form enables him to utilize his unique draconic Magic Origin alongside the perks that his biology normally gives him; his biological structure has been perfectly attuned to how his Factor of the Dragon functions; more specifically, since with every breath, the Unbreakable Dark generates energy independent from his body; which, through application of magical manipulation, grants him the ability to reinforce the sheer power of his own body with him signature element. But of course, no matter whom is utilizing this amazing power, when inducing the activation process for Black Dragon Slayer Magic and thereby performing the signature darkness manipulation of the magic, the caster utilizes an activation sequence not dissimilar from darkness-element magics of all kinds such as Darkness Magic, Shadow Magic, Darkness-Make, Shadow-Make, Dark God Slayer Magic, and much less notably due to being a loser belonging to a,. This involves the wielder of Black Dragon Slayer Magic focusing intently as they release the arcane energies that are dwelling within their Magic Origin outwards into the vicinity, from here inducing the usual fusion of eternano that's ambient within the atmosphere and said arcane energies as they take the concept of magic equaling the feelings of the magician to its absolute zenith – fuelling the fused energies with negative emotions in a manner that's not dissimilar to the Black Arts or a Curse, the user of Black Dragon Slayer Magic is capable of manifesting their magical powers in a dark and malefic nature that's said to be a variant of dark energy, a unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe, all while drawing any source of darkness towards them, placing outside sources under their thrall while drawing from the inner feelings of humanity that they kept locked away, afraid of all of those hypocritical judgmental types whom are no different than themselves – this is recognized as the "way of the wicked" (邪道, Jadō), connoting the presence of shadows, darkness and foreboding - by itself, darkness is mostly used to cloud everything into total darkness, but by accessing a dimension of dark energy it can be channeled to a variety of effects, both as an absence of light and a solid substance.

Despite the boons bestowed upon the user as mentioned in the base description for all forms of this magic, the traits such as dramatically enhanced physical prowess and senses can be said to simply be side-effects of having the physiology of a dragon; indeed, the greatest ability of a wielder of Black Dragon Slayer Magic is also its signature power – calling upon the assets of a dragon even if their bodily structure isn't one-hundred-percent the same as the beings from which this magic originated, the caster is capable of inducing a metamorphosis of their body structure as to take upon traits of a dragon instantaneously which is done in conjunction with the activation sequence of their dark energies, bestowing upon the user of Black Dragon Slayer Magic; draconic lungs and enhanced vocal folds that are capable of spewing dark energy in the form of rays of darkness, rigid plates known as scales that grow out of their skin which are laced with dark energies as to provide protection against all negative effects of darkness, and fierce claws and nails which are enshrouded with darkness, specifically attuned to dealing incredible amounts of damage – all of this combined, results in the physiology of a Dragon Slayer transforming their entire existence into that of a make-shift weapon whose ownership is unique to them and them alone, wielding the element of photons harnessed by their dragon and passed down to them alongside the natural physical superiority of a dragon in combat, utilizing offensive ability, stamina, and vitality, to transmogrify themselves into the greatest weapon of all, thus dramatically increasing the damage inflicted upon anything that they come into contact with using the sheer force of their strikes in all ranges – however, as one may have suspected, close-combat is where Dragon Slayer Magic usually shines thanks to the overwhelming physical might of a dragon, as the magic massively bolsters the power of their unarmed blows with the user unleashing powerful close-range strikes that are empowered with wakes of destructive dark energy which wreak havoc on anything and everything that they come into contact with, whipping up innumerable black storms and blasts with every movement taken. Effectively, this grants the user of Black Dragon Slayer Magic the ability to manipulate, modify, consume, and generate from their body both shadows and darkness which themselves are byproducts of dark energy to their fullest extent- they have absolute dominance over anything considered "dark", and everything related to and dwelling within all aspects which compose this Dragon Slayer Magic's element.

By transmogrifying and synchronizing their existence with dark energy, the caster of Black Dragon Slayer Magic becomes the physical personification of darkness, acting as the all-encompassing void which acts as the counterbalance to light. The darkness manifested is essentially made of pure negativity and not from the lack of illumination, essentially tapping into the core of different forms of darkness itself to assert their dominion. These dark energies are capable of being employed in almost countless other ways, with the user being capable of manifesting the three distinct parts of a shadow, emitting it in vast amounts, enough to cover a wide area. Because of the properties of Black Dragon Slayer Magic, the energies that this form of Dragon Slayer Magic releases is automatically empowered by strong feelings, albeit the likes of dark-associated magics such as Darkness Magic, the Black Arts, and Curses, which allows the caster to use darkness in a physical form for attacking, allows the user to manipulate life and death, and are the main form of combat commonly utilized by demonkind, respectively - Black Dragon Slayer Magic incorporates theories and properties of the above-mentioned trio of diabolic arcane skills in order to produce a "supreme evil", as Black Dragon Slayer Magic runs off of negative emotions in order to empower the base ability of the magic; drawing upon the user's negative emotions in order to bolster its own power and manifest their negativity in a physical form, in that way, Black Dragon Slayer Magic could be considered a Dragon Slayer Curse (滅竜の呪法, Metsuryū no Jūhō), as while magic runs off positive emotions, Curses run off the exact opposite, with their power holding an origin in negative emotions displayed by humans, mainly greed, envy and hatred, making it far more powerful as no matter how many people would display positive emotions, negativity would always be there in a greater quantity- Black Dragon Slayer Magic is no different; gaining strength from all negative emotions such as anger, fear, disgust, jealousy, sadness, and all sub-categories of said emotions; this, Black Dragon Slayer Magic can be considered to be an existence that's not dissimilar to the likes of a Devil Slayer Magic. Through their power over negative emotions, the caster's darkness can be considered a manifestation of negative energy and can use negative feelings or behaviours of others, controlling all negativity, whether it be physical or spiritual as to use different forms of emotions to boost the power of this Dragon Slayer Magic seem to bestow upon the magic various properties, such as anger having the dark energies burn through everything in their path as well as giving the dark energies powers akin to anti-matter, nothingness, as well as the unique property of gravity, bestowing the wielder with immense destructive potential overall.

Even so, like its parent magics, despite drawing upon negative feelings and a force commonly seen as 'evil', Black Dragon Slayer Magic is not inheritable evil in a sense, as like most other magics, what the power of this arcane fragment doesn't indicate whether the power is good or evil, heroic or villainous etc, and darkness and shadows don't necessarily symbolize evil, ungodliness and corruption. But still, the more that the caster harnesses the power of this Black Dragon Slayer Magic, the more risks that continuously using it has a chance of seriously endangering the user's mental state – once the first crack in their psyche has been formed, something certainly out-of-the-ordinary for a Slayer Magic begins to manifest. The sign of Black Dragon Slayer Magic's negative emotions empowerment mechanic beginning to affect the user's mental state manifests itself in the form of a demonic creature born from the negative emotions they have experienced from their soul known as a Darkside (, Dākusaido lit. Malefic Phantasmal Mirror Image) that commonly appears in the form of their own shadow. It is known that this demonic existence can influence the caster's mind and coerce them into morally questionable actions; while the user can initially ignore the suggestions of this twisted mirror image of themselves, but as the darkside continues to offer them more power by making a deal with it, it becomes harder and harder to pretend this being doesn't exist; though the Darkside and the negative emotions empowerment of the magic, as well as such a strong ability, the sheer weight of Black Dragon Slayer Magic's power will normally slowly erode the user's morality, with 'absorbing it into the shadows' becoming their solution and reaction to everything. The user slowly drowns in their immense strength, and even the noblest of souls can gain hearts as black as pitch—essentially, one way or another, a user of Black Dragon Slayer Magic will fall to the side of darkness without any way out. However, as a very small consolation prize, the further they fall, the stronger the user becomes. But, of course, it should be noted, those with a clear mind are capable of bringing out the full potential of this magic without succumbing to the Darkside and corruptive element. Through the invocation of a similar process to Crystallos Forge of Crystal Dragon Slayer Magic and Photonic Forge of Photon Dragon Slayer Magic, the caster is capable of using Shape Transformation on their dark energies as to forge it in the shape of constructs, which can be utilized in various manners in a manner not dissimilar to Molding Magic, these tools and familiars used for offense and defensive maneuvers to keep the opponent on their feet; a user of Black Dragon Slayer Magic can also control and manipulate beings of shadow and darkness, create and dispel shields and areas of total darkness.

Thanks to its association with the concept of "evil", Black Dragon Slayer Magic's dark energies possess properties that induce a decomposition effect on anything that it happens to come into contact with, as both organic and inorganic substances are broken down into much simpler forms of matter, rotting everything in its path, functioning similarly to a deadly miasma, a poisonous vapor filled with particles from decomposed matter that causes all sorts of illnesses, the deadliness of such increasing in the presence of environmental factors such as contaminated water, foul air, and poor hygienic conditions, and these dark energies are known to be able to spread through airspace in a slow rate but with equal effects on the surroundings, turning the caster's body into a walking wasteland. Something interesting to note is that Black Dragon Slayer Magic has a side-effect known as Hades Charge (, Hadesu Chāji lit. Everlasting Darkness Escalation) which enables the user of Black Dragon Slayer Magic to bolster the power of their attacks; when inducing their regular attacks, the caster is capable of adding more power when they is initiating the attack to achieve a higher level of power; this process, while it does result in the spell being launched at an ever-so-slightly later date, it can drastically enhances the power, width, and size of spell, and as such, the option of charging can mean the difference between victory and defeat in the heat of battle. Generally, the charging speed of any dark-based spell takes about two seconds down to the letter, and when increasing the spell's power, the caster adds more and more of their darkness into the spell, drawing it from outside sources such as the negativity in the atmosphere, the night sky, or the ambient eternano in the immediate vicinity. The caster is also capable of continuing to hold the spell in its magical energy compressed form and move around as normal; this can serve as a way to take advantage of extra power while taking evasive action. Finally, Black Dragon Slayer Magic also has a side-effect known as Shadow Erosion (, Shadō Erōjon lit. Soul-Stealing Darkness), which, as its name would indicate, can absorb the life of living beings and even Níðhöggr's fellow dragons, absorbing their power for the Dragon King's own use through engulfing their existences in the malefic shadows that break their bodies down to the atomic level and then convert these particles into that of shadows, enabling Níðhöggr to absorb them into his Dragon Factor, resulting in him receiving a notable boost to his physical and magical parameters. Because of this devious power, with the exception of the Dragon of Dragons, Níðhöggr is regarded as the strongest of the anti-human faction, if not dragonkind in general.

As with all forms of Dragon Slayer Magic, Black Dragon Slayer Magic has virtually unlimited customization options in regards to the element formed through simple magical manipulation and reinforced through the power of a dragon – the colour of the dark energies produced by the magic is able to be altered freely, its properties which aren't limited to but include temperature, the smell that it emits, its taste, and overall "feel" is capable of being modified to the user's liking for countless different effects and powers, more often than not being attuned to the user's own personality and ambitions; they are capable of utilizing the darkness in any way they wish, whether for offensive, defensive, evasive, or supplementary techniques- as long as they can imagine it being doable, then the sky is the limit, more or less. In its normal state, Black Dragon Slayer Magic seems to have a "bludgeoning" effect to it, seemingly causing armour-pulverizing damage alongside the user's burning ambition given a corporal form in their element; but they can be used in several other different ways, allowing for a high level of adaptability; the shadows are able to be released in freeform, as condensed, or even molded into the shape of a weapon, taking on the properties of said chosen shape. The shadows and darkness that are produced by Black Dragon Slayer Magic is far swifter and powerful than any normal dark-based powers; it is shown on multiple occasions that Black Dragon Slayer Magic is superior to any Slayer Magic or any other Lost Magic-based darkness- in addition to darkness-based Curses. Not only this, the user has such mastery over the element of darkness and shadow that they are capable of utilizing it in any way that they wish, whether for offensive, defensive, evasive, or supplementary techniques- as long as they can imagine it being doable, then the sky is the limit, more or less, making this magic akin to a much lesser Arc of Embodiment. For this, Black Dragon Slayer Magic's level of control over the concept of "dark" is regarded to be nothing but a pipe-dream for other dark-manipulating magicians to achieve. It seems that the energies that are produced by Black Dragon Slayer Magic are capable of absorbing opposing sources of darkness, even moonlight, in order to make it both phenomenally faster and stronger; making it near-invincible and making the user an absolute terror to fight against, with the user of Black Dragon Slayer Magic possessing a certain ability to sniff out darkness and negativity; since darkness can be found in the hearts of others, and, because of that, the user of Black Dragon Slayer Magic can consume the dark energies inside of others to increase their powers and restore their stamina and magic capacity. However, those with a pure heart are immune to the dark influence of this magic, even though according to the user; there is no such thing as a "pure heart". In addition, the user can consume external sources of darkness and shadows to restore their body to a healthy state and regain their reserves of strength, something that also makes them immune to all types of darkness and shadows, due to their capability of nullifying dark-based attacks by sucking them in and eating them; the consumed element also seems to possess a different "taste" according to its "quality". However, the user can't eat their own darkness/shadows, or imbued with dark by themselves, to reinvigorate themselves.

Supplementary Abilities

 * Shade Forge (, Shēdo Fōji lit. Pseudo-Darkness Molding Magic): Shade Forge is a special sub-ability of Black Dragon Slayer Magic- it can be considered an existence similar to that of the Darkness-Make Molding Magic. Shade Forge is the main usage of Black Dragon Slayer Magic other than simply using it to bolster the user's close-quarters capabilities; in any case, Shade Forge is triggered by the user taking the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them, placing outside sources under their thrall while drawing from the inner feelings of humanity that they kept locked away, afraid of all of those hypocritical judgmental types whom are no different than themselves – this is the way of shadows; however, unlike regular Black Dragon Slayer Magic, the user can only manifest it lightly, that is to say, that they are only able to project the darkness one or two feet ahead of themselves. However, that is where Shade Forge's full power comes into play—if the user understands the inherent structure of the properties about to be reproduced in their mind; including the flow and balance of magical energy within, they can use the darkness in order to perfectly replicate the structure of the identified material, using the darkness to cause the manifested item in a more malleable state, completely unlike its regular version, as to allow it to be easily reshaped into a new form, reforming the material into a new shape that they deem suitable in a matter of seconds. The shadowy structures that the caster manifests all carry the natural overwhelming power of Dragon Slayer Magic, even when the user isn't touching them, making them a cut above most other forms of structure-creation magic; indeed, the only limitations are the user's own imagination, and it requires no prior movements which are all in-born with Molding Magic, instead, the user can form countless items simply by shaping their magical power and thinking about it, not even using the proper modification technique known as Shape Transformation in order to bring their thoughts into reality; for this reason, it can be said that Shade Forge is far more effective than bog-standard Darkness-Make or powers similar to it. With Shade Forge, the user is able to draw any darkness or shadow from any source, including the night sky and their own shadow; though they able to manifest darkness from their own magical power, but this is relatively taxing on their body and magic reserves, which is why it is preferable to draw their element from natural sources. Like regular Black Dragon Slayer Magic, Shade Forge's substance is known to be extremely destructive, capable of obliterating almost anything in its path as the eternano composing the darkness accelerates the moment of contact with a physical being, causing it to explode momentarily, before reverting to its previous state and continuing to travel forward. As the user is capable of molding darkness from the night sky, Shade Forge becomes exponentially more powerful at night—making a user of the magic considered nearly invincible, with only a few weaknesses to exploit. With high-level Shade Forge, it is possible to manufacture an exact replica of objects using darkness as the primary material. Despite all of its near invincibility as darkness can be procured from nearly everything and anywhere, Shade Forge's greatest weakness is that by drawing upon the element of the night sky; darkness, the user subjects themselves to the full brunt of the negative emotions that compose Black Dragon Slayer Magic. There are two forms of Shade Forge; the first is called Static Shade Forge. This type of Shade Forge is characterized by the creation of inanimate objects, such as weapons, or by affecting the environment around them. The second type is called Dynamic Shade Forge. This type of Shade Forge focuses on creating animate shadowy sculptures, usually in the form of animals; though human body parts and the like can also be formed. Dynamic Shade Forge is said to be more quickly cast than Static Shade Forge. While both styles of Shade Forge have their own pros and cons, there is no clear "superior", leaving the matter of which style is "stronger" up to how much both versions evolve.
 * Static Shade Forge (, Sutateikku Shēdo Fōji lit. Tool-Forging Pseudo-Darkness Molding Magic): Static Shade Forge is one of two methods to utilize Shade Forge- it is characterized by the creation of inanimate objects, more often than not weaponry and tools to suit the situation at hand. In terms of use, Static Shade Forge is known to be the user's preferred method of using the sub-ability, as weapons are relatively easier to manifest and keep in-action for long periods of time in contrast to the summoning constructs of the Dynamic version of Shade Forge. Generally, each construct is capable of matching a real steel weapon blow-for-blow without shattering- Static Shade Forge can be utilized to form almost any weaponry at all, and the user capable of conjuring anything from nothing. Close combat weapons such as swords and spears can be created effortlessly, though due to the intricate workings of existences such as guns, they are slightly more difficult; shields and staves can be reproduced with a much greater struggle, as the cost in magical energy is high, two or three times greater than a bladed weapon. As the user's most favoured method of utilizing Shade Forge, Static Shade Forge has reached the point where it can be considered mastered already. During the heat of battle, the user more often than not forms various weapons with a single snap of their fingers or by affecting the immediate vicinity where combat is ongoing, granting advantages to them and hampering their opponent(s). One of the user's most common uses of Static Shade Forge is to affect the ground beneath them by jabbing darkness whether it has already been shaped or not into the soil below, inducing Shadow Erosion upon the surface and everything that entails in order to convert everything into darkness in the environment around their figure, reducing the soil to nothing, at which point, the user can manipulate and shape these newly-formed shadows in any manner that they please- effectively, because of this, when combined with the elemental consumption method of Dragon Slayer Magic, enables the user to permanently possess freedom of movement no matter what as well as devour everything in sight to regenerate.
 * Dynamic Shade Forge (実降・偽性・闇の造形魔法|ダイナミック・シェード・フォージ}}, Dainamikku Shēdo Fōji lit. Entity-Summoning Pseudo-Darkness Molding Magic): Dynamic Shade Forge is the second form of Shade Forge; it involves the user creating familiars forged from darkness. These familiars are formed when the user focuses more magical energy into the formation of their Shade Forge magic seal while envisioning a proper 'guardian', at which point, the user can manifest them from their magic seal- these beings of darkness take upon a black smoky colouration and emit a soft glow and generally have hundreds of eyes emblazoned upon their existences. While Dynamic Shade Forge focuses on animals of darkness, human body parts and the like can also be formed; the user can also manifest full humanoid beings; the user more often than not utilizes the creations made manifest by Dynamic Shade Forge in order to assist them in battle, be used as diversions from all sorts of incoming blows, and last, but not least, as a means of transportation to reach heights that would normally be considered impossible or to evade an enemy's onslaught. Dynamic Shade Forge is said to be more quickly cast than Static Shade Forge; though they generally cost more magical power to maintain due to Dynamic Shade Forge summoning beings which more often than not requiring the user to direct and command them; though after a while, these demonic guardians are capable of displaying free will and thought, making all sorts of movements on their own judgments based on the current situation, allowing them to take appropriate action in many cases. With Dynamic Shade Forge and a good memory, the user has the ability to summon avatars of the foes that they've defeated, the stronger they are the better. The user is said to not really be interested in Dynamic Shade Forge as they prefer to fight their battles themselves, but the original dragon who used the magic was noted to be an absolute master of this version of Shade Forge, manifesting entire armies from nothing to run wild upon those who opposed them.
 * Shadowsinker (, Shadōshinkā lit. Black Dragon's Darkness Body Transformation): Shadowsinker is a core aspect of Black Dragon Slayer Magic and one of the magic's most powerful assets; effectively, it's a drastically more effective version of the Shadow Body spell, which is a darkness-based version of the Elemental Body ability of Elemental Magic, which allows the user to let physical and magical attacks pass harmlessly through their body when they're transformed; but Shadowsinker is a permanently available ability - Shadowsinker enables the user of Black Dragon Slayer Magic to transform their body into shadows, allowing them to sink into the ground in order to roam around freely at high speed and teleport. When inducing Shadowsinker, the user takes the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature which now begins to surround their body, enveloping the caster in its entirety before the malefic powers of the shadows reduce their existence to black wispy smoke and embers – this is actually their own magical energy influenced by Black Dragon Slayer Magic, essentially transforming their very body into that of shadows, which cannot be touched by normal means. This shadowy from grants the caster near unparalleled speed and an immunity to harm when transformed; essentially granting them the status of semi-flight. With Shadowsinker, the user is capable of closing the distance between themselves and their enemies, and can even use it go through them, attacking and then re-materializing continually as a form of a 'speed blitz'. Since the user is capable of transforming their body into shadows, the user can use the shadow dash to go through structures with openings, like chain-link fences, iron bars and pipe-like structures; they can simply escape through ventilation systems and anything that has the smallest of openings, making the user of Black Dragon Slayer Magic virtually impossible to corner unless under specific circumstances. With Shadowsinker, the user can squeeze through tight passages, or move objects about –they could pull a person out from under a mob attacking them by dispersing and reforming them nearby, or steal their opponents' weapons by vaporizing them into their hands and bringing them to their own. The user can move around with a partner, or send objects to a new location within traveling with them, providing they can visualize the new location in their mind; an extension of this is that the user of Black Dragon Slayer Magic is capable of engulfing a target with shadow by sending it towards them instead of using it to surround themselves, this causes the target to float above the ground, being guided by their hand in a similar manner to that of Telekinesis. More often than not, the user of Black Dragon Slayer Magic milks Shadowsinker for all it's worth, and, in a fight, uses the ability to constantly disappear and appear at will, hitting, running, and flanking without any effort at all and barely any threat of counterattack. While in this state, all physical and magical attacks are negated, and, this renders others' ability to track the user null and void- not even some form of Sensory Magic can notice the user of Black Dragon Slayer Magic; with Shadowsinker active, the user often only appears as a black shimmer of energy, with only the fastest foes even catching sight of their true figure during a battle as they dodge efficiently and make surprise attacks from all angles available; they are also capable of sinking others into the depths of their shadow, enveloping them with Black Dragon Slayer Magic's Shadow Erosion power; one of the most dangerous abilities that Shadowsinker bestows upon the caster is the power to link to the shadow of the opponent, allowing them to never miss with their attacks as every strike that the Black Dragon Slayer Magic user performs would involve them quickly emerging from the opponent's shadow and then striking them with any type of power in the back. The user can also perform maneuvers such as creating a swirling vortex that pulls in and "devours" any and all targets they deem suitable, as well as causing shadows to erupt from the ground in a singular burst that blows the target into the air as they receive a fair amount of damage. However, as a bit of a downside to the great versatility offered by Shadowsinker, if the user is caught while in a tangible form, or by another person in shadow form, they are then vulnerable to any sort of attack. An Elemental Body spell always takes some "phase time" to complete the transportation, during which the user cannot do anything else: for this reason, it is seldom used in combat. Shadowsinker however, is a power which can reduce the phase time to a level suitable for combat down to zero. The caster can perform Shadowsinker mid-combo as well, causing the enemy's attacks to miss while simultaneously acting as attack cancels for themselves; and with it, they can move at speeds up to one hundred and twenty kilometers per hour, the maximum velocity at which they are still able to breathe. However, the weakness of Shadowsinker is that it normally takes the user a split second to transform their body into shadows, preventing the caster from moving out of the way of enemy attacks if they are too slow to activate Shadowsinker.

Basic Spells

 * DarknessRoar.pngUmbra Erga (, Anbura Eruga lit. Black Dragon's Roar): Umbra Erga is the hyperresonance ability of a dragon, attuned to the element of darkness and shadows - as such, it works best with Black Dragon Slayer Magic. When performing Umbra Erga, Níðhöggr utilizes his enhanced lung capacity in order to gather and condense ambient eternano from within the atmosphere and store it momentarily within his mouth- from here, Níðhöggr attunes the eternano gathered by merging them with his energy in order to induce the usual fusion to being power into the current realm; this results in the Unbreakable Dark going the opposite of the 'magic = feelings' concept—by Níðhöggr fuelling his magic with negative feelings, he is capable of initiating the usual fusion of eternano and magical power, only manifesting magical power in a dark and malefic nature; he draws more and more darkness into his massive jaws from which no flying, talking cats have ever seen the light of day until he has gathered enough to the point that just by propelling it outwards, he could cause a bombardment of malefic energy that covers an entire continent. When charging the Umbra Erga, Níðhöggr's mouth begins to glow red as his veins light up, but in any case, once this is done, in order to unleash the magical energy, Níðhöggr utilizes the Dragon Cords (竜帯, Ryūtai), a dragon's equivalent of vocal cords which produce a louder and harsher sound while amplifying anything emitted from his mouth tremendously, resulting in a massive blast of energy spewing forth from his mouth towards the target; in the case of Umbra Erga, the form it takes is one of a powerful chain reaction akin to nuclear fission; as the magical energies in the Black Dragon's mouth will rumble violently as they quickly spiral outwards before manifesting as upon release, the magical energy collapses in on itself then expands outwards rapidly towards the enemy; a flare is a contained release of energy, which fully exposes the enemy to the source rather than blow them away from it after a while. When charging the Umbra Erga, Níðhöggr's mouth begins to glow red as his veins light up, unleashing this energy in the form of an enormous black beam of darkness, at least three kilometers in width, that has a red outline. The trajectory of the laser can be altered, allowing the Black Dragon to strike more than one opponent. The whiplash of the attack can be quite huge, usually blowing apart anything behind the Dragon King at the time of attack. Along with its astounding destructive power, the attack has a delayed effect if the initial blast should fail, wherein the target will be blasted by residual effects left over by the beam; which manifests in the form of orbs of darkness, which lock-on to Níðhöggr's opponents no matter their position, chasing after them. They can dodge obstacles in their way, unless it is not physically possible, never ceasing their hunt until they catch their prey. As it darts through the air, the blast released by Umbra Erga is capable of inducing a decomposition effect on anything that it happens to come into contact with, as both organic and inorganic substances are broken down into much simpler forms of matter, rotting everything in its path - as per the traits of Black Dragon Slayer Magic, Níðhöggr's Umbra Erga can function similarly to a deadly miasma, a poisonous vapor filled with particles from decomposed matter that causes all sorts of illnesses, the deadliness of such increasing in the presence of environmental factors such as contaminated water, foul air, and poor hygienic conditions, and it is able to spread through airspace in a slow rate but with equal effects on the surroundings. It goes without saying that the Dragon's Roar of Níðhöggr can deal a great amount of damage to any opponent with an enormous explosion upon contact, leaving huge mushroom cloud; similar a nuclear bomb; this effect spreads out to a fan-shaped area, and is easily capable of destroying several buildings in a single strike; reducing an entire desert to naught but a long-spanning sheet of molten glass; at full power, Umbra Erga can completely eradicate an island, imprinting a giant crater into the ocean.
 * Umbra Erga – Condenshot (, Anbura Eruga – Kondenshotto lit. Black Dragon's Roar: Focused Ordinance Edition): Umbra Erga – Condenshot is a variant of the standard Umbra Erga attack of Black Dragon Slayer Magic; in this case, Umbra Erga – Condenshot is a compression of the innumerable quantities of shadow launched out of Níðhöggr's mouth into the form of a gigantic orb of swirling shadow that devastates everything in its path. When performing Umbra Erga – Condenshot, Níðhöggr first inhales, gathering eternano within his mouth to gather and condense ambient eternano from within the atmosphere and store it momentarily within his mouth- from here, Níðhöggr attunes the eternano gathered by merging them with his energy in order to induce the usual fusion to being power into the current realm; this results in the Unbreakable Dark going the opposite of the 'magic = feelings' concept—by Níðhöggr fuelling his magic with negative feelings, he is capable of initiating the usual fusion of eternano and magical power, only manifesting magical power in a dark and malefic nature. At this point, Níðhöggr initiates the usual fusion of eternano and magical energies, causing the combined mass of energy to become the embodiment of negativity as the gathered energies combine to act a propellant to the shadowy attack, charging it up for a few moments; this also induces a gravitational attraction that begins to pull objects towards Níðhöggr as the energy contained within his mouth becomes larger. Once the charging phase has been completed, Níðhöggr unleashes a mighty roar that doesn't release a gigantic laser of darkness, but rather, a pitch-black and purple pulsating orb of energy with black static around it shoots forth with a speed and force beyond that of a bullet, destroying everything that the sphere of darkness so much as passes while in motion, focusing on dealing smashing damage which can bust through and completely flatten anything and everything in its way; but upon contact with the designated target, Umbra Erga – Condenshot explodes viciously, blasting away everything in the immediate vicinity.
 * Darkness_Dragon_slayer_magic.jpegBanishing Fang (, Banishingu Fangu lit. Black Dragon's Slashing Iron Claw): Banishing Fang is the basic close-quarters spell of the Black Dragon Slayer Magic, akin to, , , and Solar Dragon's Firing Hammer; effectively, with Banishing Fang, the user of Black Dragon Slayer Magic covers their arm with shadows before slashing at their target. In any case, when performing Banishing Fang, the user of Black Dragon Slayer Magic begins to invoke their dark-based powers by taking the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them while focusing it around one of their arms, resulting in a compression of pulsating shadows around their hand that's mainly focused around their palm, giving off the appearance of a black aura with a purple outline – these shadows constantly flow outwards and their specks of black scatter to the winds for the brief duration that the spell is in its preparation stage. From here, the user charges immense amounts of darkness within one of their hands, with their hand assuming an open-palm formation, the tips of their fingers pointing downwards palm-wise. With this, the user slashes forward with their "claw" at high speeds, inflicting major damage and launching them far away, creating an impact force which is powerful enough to propel the unlucky recipient several meters away. The incredible speed both makes the strike far more powerful, and harder to dodge. Once Banishing Fang makes contact with the opponent, the searing, unholy properties of the darkness manifest fully, spelling bad luck or even worse for the enemy, as the sheer force and velocity of the user's hand movements only bolster their elemental attack, granting a powerful attack capable of gouging a hole in the enemy's body, no matter how resilient they are, even if they're harnessing any form of power booster- countless fellow Dragon Slayers, especially Second-Generation Dragon Slayers, have fallen to the overwhelming power of this spell, despite how deceptively simple it looks. The amount of time in which these actions transpire make it seem as if the opponent has been slashed with the force that could cleave several skyscrapers in a row in twain effortlessly, blowing them away instantly after the spell has been performed. The caster is also capable of projecting the shadows of Banishing Fang outwards by thrusting forward with their hand after manifesting the shadows on their hand, launching it as a claw-shaped aura at their target which serves as an impromptu projectile attack.
 * Banishing Fang: Raid (, Banishingu Fangu: Reido lit. Black Dragon's Slashing Iron Claw: Crushing Fang Devoured by the Darkness): Banishing Fang: Raid is an extension of the regular Banishing Fang Black Dragon Slayer Magic spell; it's a version of the standard Banishing Fang where the caster lashes out at the target with an open palm before dividing the shadows on their hand into numerous thin tendrils to bombard the target; functioning similarly to or . When inducing Banishing Fang: Raid, the caster can either use it once in close-range with the original Banishing Fang spell already activated, or begin a new Banishing Fang. But when invoking Banishing Fang: Raid, the user of Black Dragon Slayer Magic takes the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them while focusing it around one of their arms, resulting in a compression of pulsating shadows around their hand that's mainly focused around their palm, giving off the appearance of a black aura with a purple outline – once this is done, the user strikes forward with all of their might, unleashing the concentrated shadows upon their arm towards the foe, resulting in the caster momentarily placing their hand upon the enemy's body in a grabbing motion as they unleash their darkness, causing a powerful surge that splits the shadows condensed upon the user's arm into a dozen tendrils that bombard the opponent with vicious lashings that transfer the user's own darkness into the opponent's body. While the attack is being performed, Banishing Fang: Raid has the unique ability of allowing the user to grab onto an opponent in midair; and in any case, once grabbed, the user is capable of throwing the opponent in two directions, forwards and backwards. If the user hits their enemies farther away, then their opponents will be sent upward with high vertical knockback.
 * Banishing Fang: Spike (, Banishingu Fangu: Supaiku lit. Black Dragon's Slashing Iron Claw: Erupting Pillar): Banishing Fang: Spike is an extension of the regular Banishing Fang Black Dragon Slayer Magic spell; it's a version of the standard Banishing Fang where the caster gathers the shadows amassed around their hand and surges them into the ground, resulting in a powerful pillar of darkness that erupts from the earth, damaging anything in its area-of-effect in a manner similar to . When performing Banishing Fang: Spike, the user takes the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them while focusing it around one of their arms, resulting in a compression of pulsating shadows around their hand that's mainly focused around their palm, giving off the appearance of a black aura with a purple outline – once this is done, the caster slams their open shadow-clad palm into the barren earth, transferring the darkness imbued upon their arm into the ground itself, resulting in a minor earthquake resonating throughout the area and shaking the surface for the briefest of moments – the earth bursts open as a torrent of darkness that swirls around at high speeds in the shape of a pillar erupts upwards. As per being oriented towards offensive measures, the pillars are known to possess immense slashing power if used in such a manner, and can pierce all sorts of defenses, whether they are natural or supernatural in nature, ranging from Magic to Curse-derived. Generally, the user harnesses Banishing Fang: Spike by launching it towards his enemies- by simply stomping smashing their palm into the ground, they release two pulses of magical energy from their shadowy hands, resulting in fissures erupting from the earth, travelling in the direction of their opponent- while in motion, the fissures generated cause the earth to shake violently with a force akin to a minor tremor that ends with absurdly sharp pillars of darkness erupting in a continuous row while they rush towards their opponent like a multitude of sharks submerged within the earth, leaving only their fins visible, chasing the enemy until certain doom is met; even after the strike, the pillars of darkness persist in rising before dissipating into the skies. This variation is so incredibly powerful that it is able to plow through several buildings in one shot.
 * DarknessUmbra.pngDoom Bringer (, Dūmu Buringā lit. Black Dragon's Waxwing Flash): Doom Bringer is a Black Dragon Slayer Magic spell which enables the caster to unleash a powerful and far-spanning shockwave of darkness and shadow that envelops everything that it comes into contact with and subjects them to Shadow Erosion all in a manner akin to . When performing Doom Bringer, the user takes the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them while focusing it around their entire frame for the briefest of moments as the caster raises their hands above their head, turning their shadows a pulsating crimson as it starts constantly being compressed as it collects and concentrates the light of the moon and the stars into its structure, which produces such a radiance that it illuminates the area but is quickly drowned out by the negative emotions of Black Dragon Slayer Magic; all focused around the caster's hands which increases in both quantity and intensity with every second, gathering and condensing more and more magical energies to add to the mass. Once enough energy has been gathered to the caster's liking, they slam their arms into the earth palm-first, sending the shadows compressed upon their arms into the ground below, causing the immense amounts of darkness compressed into the user's hands to be unleashed at full power in the form of a crimson and pink pulsing and glowing shockwave of feather-like shadow to ripple outwards from the caster's body at speeds beyond mortal comprehension, propagating through the point of impact, shaking both the medium and anything around it, causing the objects around the point-of-impact to vibrate erratically in an extremely hard and fast wave, which causes other things that the material touches to vibrate too, resulting in a powerful explosion that does even more damage – it is called a "shock wave" because the wave of concussive force reverberates up and down like a crashing wave in the ocean. Doom Bringer's release damages the surrounding environment, blasting through the medium it was transferred through at astounding speeds in any direction that the caster chooses upon release; these shockwaves of shadow can ripple through the ground or in the atmosphere, bringing mass destruction to anything that they come into contact with- they can repulse enemies away with incredible force while pushing over those on the fringe of the glowing shockwave and shattering delicate substances; at the highest point, Doom Bringer can even cause minor earthquakes by shaking the ground or dislodging underground tectonic plates. The power of this spell can uproot trees, rend the earth, cut the skies, and smash small buildings, radiating throughout the vicinity, even disrupting enemy spells if they are being cast at the time, sending them careening across the landscape in the blink of an eye. Accompanying Doom Bringer is a smoke-like miasma that radiates outward from the caster which immediately ages and rots anything that it comes into contact with, moving fast enough to strike even the fastest of mages. Even after escaping the attack, the deterioration continues until the target's afflicted area had been amputated. Another notable aspect of the ability is that the caster can control its speed. This spell can even dissolve certain spells, while some top-tier defensive or barrier spells and/or seals can only be partially damaged or can even remain untouched. Interestingly, the thicker the aura is around the caster's arms, the more powerful the attack becomes.

Supplementary Spells

 *  (, Shadō Doraibu lit. Third-Generation Dragon Power Amplification: Darkness of the Outer Limits): Drive is a Dragon Slayer ability is a type of Magic-amplification technique used by Third Generation Dragon Slayers that brings out the true power of their capabilities as a user of Dragon Slayer Magic, excluding the power boost granted by Dragon Force, yet, at the same time, seemingly enhancing the user's physical prowess to a degree, particularly the user's speed. In the case of Shadow Drive, and by extension, a Black Dragon Slayer Magic user, Shadow Drive infuses the darkness that each user of Black Dragon Slayer Magic can generate with their magic into their bloodstream, which reaches their brain, resonating with the adrenaline that the user experiences in the heat of combat. This, in turn, reacts with the Black Dragon Slayer's own body and their Magic Origin, and their Lacrima begins to distribute the Dragon Slayer Magic Particles stored within the crystalline orb at a swifter pace, accelerating the output and flow of magic from the Lacrima to the user's body in order to enhance all of their fortes, increasing the strength, speed, and potential that the user possesses tenfold, allowing them to take on even foes much more powerful than themselves; entering a state of enhanced awareness and peak physical ability as shadow and darkness cloaks around them. When this process is occurring, alongside it, the darkness ever-so-signature of Black Dragon Slayer Magic begins to automatically activate, taking the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, automatically initiating the usual fusion of eternano and magical power, but only manifesting the caster's magical powers in a dark and malefic nature while drawing any source of darkness towards them, granting them an aura of shadows that completely cloaks and continuously rises from their body while simultaneously whirling around the caster in a rippling manner; activating Shadow Drive, the user's eyes become obscured by shadows, leaving only their round and blank irises visible. Essentially, Shadow Drive causes the user to become cloaked in intense shadow, allowing the user to better employ their Dragon Slayer Magic whilst at the same time massively enhancing their physical prowess to a degree, particularly their speed; while it is said that Drive channels the powers that "kill dragons", this is particularly unknown as it has never succeeded. Shadow Drive has a notable amount of startup invincibility, so if their opponent is attacking the user while they are activating the skill, the user will be capable of counterattacking immediately as to turn the tides instantly. As a result of Shadow Drive, the user's base power level, strength, speed, and senses greatly increase; tripling their already impressive power, allowing for a massive boost all across the board.
 * Shadow Drive – Phantom Pain (, Shadō Doraibu – Fantomu Pein lit. Darkness of the Outer Limits: Malefic Phantasmal Mirror Image Manifestation): Shadow Drive – Phantom Pain is an extension of the bog standard Shadow Drive power; it enables the caster to manifest their personal Darkside into the mortal plane and have them fight alongside the user. When invoking Shadow Drive – Phantom Pain, the caster takes the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them, pooling it at a singular point – their own shadow. The negative feelings hidden within their shadow – the caster's dark side – reacts to this mechanic, accepting the power gleefully as the user's magical energies link with that of the shadow's existence, causing it become shrouded with a glyph composed of magical energy, textured in black and red as it undergoes a grotesque transformation into an exact replica of the user, flanking the caster's side; however, what is different about the Darkside in comparison to the user is that the shadow is completely black with the exception of its red eyes; also wisps of darkness constantly scatter from its form. The shadow can even move and fight like them also, with the similar amount of strength as its wielder; due to the user's magical power giving it extra strength. When this is done, the shadow is linked to the user's mind. Once an exploitable opening presents itself, it can and often will lead to lengthy and unbelievably high-damage combos. The user of Black Dragon Slayer Magic can use the Darkside as a pressure and confusing tool, forcing the opponent to switch between dodging and blocking until they make an unfortunate mistake. When Shadow Drive – Phantom Pain is active, the user impossible to counter or predict without the use of clairvoyance, as the shadow does nothing, remaining in a hunched position, until commanded, meant to be as close as possible to the opponent. Many of the user and their shadow's attacks chain together; capable of dealing tremendous damage to the foe via numerous heavy blows; dodging many attacks as well as faking out the opponent, disorientating them even more. The user can also summon and recall their Darkside; however, the shadow is also automatically summoned through many of Black Dragon Slayer Magic's more powerful spells. The main purpose of the shadow is to add damage to the user's combos and to force disorientation on the opponent if they block. However, the main weakness of Shadow Drive – Phantom Pain is that when utilizing this, for stronger attacks, the user cannot use or move their body and has to have someone guard them so that they won't be harmed.

Shade Forge Spells

 * Shade Forge: Discalibur (, Shēdo Fōji: Disukyaribā lit. Pseudo-Darkness Molding Magic: The Jet-Black Sword of the Vile King): Shade Forge: Discalibur is perhaps the most basic Shade Forge creation of the Static Shade Forge line; it enables the caster to shape a sword from darkness that can be used for close-to-mid ranged combat. When performing Shade Forge: Discalibur, the caster activates Shade Forge by going to the extremes of the 'magic = feelings' concept— by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them, before they utilize their imagination in order to mold the darkness and shadows created through Shade Forge into the form of a single-edged sword composed completely from shadow, meaning that it does not possess a solid form. The Discalibur is mainly in blacks with lighter shades of grey in various places, possessing a spear-like handle that has a red diamond to serve as a pommel, and a curled and elongated hilt fashioned in the shape of a dragon's head with red eyes. The sword's blade is double-sided and shaped like a stylized 'Z'. The design of the Discalibur was made to take down enemies in a single swing, but due to its unwieldy size and a weight decidedly greater than any other sword, it is said that no one has even been able to brandish this unusual blade to its full capacity. The sword is highly sharp and durable, capable of slicing through magical barriers, and its slashes are capable of trailing large amounts of darkness in its wake, which can damage the opponent. Shade Forge: Discalibur is so deadly precisely because it's capable of being utilized in countless ways- it's almost mesmerizing that somebody can get so much mileage out of a simple sword of darkness. Shade Forge: Discalibur take the form of any type of sword formed from shadow, such as a regular sword and alter its properties to transform it into another version, such as a rapier or katana. The moment that the weapon makes contact with the foe via impaling them, the composition of the weapon is altered to cause additional, smaller blades to protrude from the blade inside of the foe's body, drastically increasing the number of wounds dealt to the foe. The weapon itself can endure even the strongest of attacks, making it quite effective in blocking and deflecting incoming attacks; and it can withstand getting crushed by force. The armament is strong and sharp enough to cut clean through pure metal weapons as well; the power of Shade Forge: Discalibur is capable of inflicting a deep cut into the opponent's body, even if they had erected a magical defense beforehand, severely damaging them- it can defeat an Etherious compared to a Guild Ace in power in a single strike.
 * Extension: Rumbling Discalibur (, Ekusutenshon: Ranburuingu Disukyaribā lit. Additional Attack: The Jet-Black Sword of the Vile King: Fervent Dancing Dragon Clawed Shadow Stitching): Extension: Rumbling Discalibur is an extension of the regular Shade Forge: Discalibur spell which involves the caster physically throwing the Discalibur at the opponent, which can pierce them and pin them to the ground afterwards. When performing Extension: Rumbling Discalibur, the user uses their Black Dragon Slayer Magic to create a sword made of darkness and shadows for melee combat; but instead of being harnessed for close-range battle, it is capable of simply being thrown, with the user launching the weapon like a high-speed projectile at the opponent, impaling them if it makes contact- the Extension: Rumbling Discalibur spell is launched forward in a similar manner to that of a rocket. These swords of darkness aim to impale the opponent with incredible speed and force. Extension: Rumbling Discalibur, when in motion, is able to cancel any type of other dark-element attack while continuing to hit the opponent; it always contains the properties of targeting and propulsion, always condensing the magical particles that compose it, before spreading them out to the tip, coating the outer surface of the swords, enhancing its penetrative qualities. Upon contact with the foe, the Extension: Rumbling Discalibur releases all of the darkness and magical particles that compose it—the foe's own magical pressure serves to contain and amplify the destructive power of the blade of darkness, piercing through anything in its path. If it, by any chance, misses, the Extension: Rumbling Discalibur expands shadows into the enemy's shadow and transforming the energies into those of the darkness of Black Dragon Slayer Magic themselves, giving Extension: Rumbling Discalibur a "stopping" effect which pins the opponent down by turning the shadowy blade into a pivot which has caught their shadow, rendering the opponent unable to move as the shadow cannot separate from the body, and in such a case only the user can remove the enemy from their bindings- it is "stitching" the opponent to the ground through Black Dragon Slayer Magic. It should be taken into consideration that in mid-flight, the blades veer off wildly in different directions, homing in on different targets in order to attempt to take out multiple opponents at once —these lock on to the target, tracking their heat signature; it is a spell that is effective for quick, widespread, and massive amounts of damage. This attack has several other versions, such as a midair version, and a variant that shoots a trio of shadowy blades at once. Something native to this spell is that even when the user is not holding the weapon, it will not vanish- multiple swords launched can be directed telekinetically. Even so, the user has a limit to how much Extension: Rumbling Discalibur shots that they can use; even if the user runs out of magical power, they can still fire a single shot; however, it loses its rapid-fire capability and it will not fire up or downwards as it did when they had magical energy, instead it will fire only straight across.
 * Extension: Discalibur – Absolute Domination (, Ekusutenshon: Disukyaribā – Abusoryūto Dominashēon lit. Additional Attack: The Jet-Black Sword of the Vile King: Open Devil God King Sword of the Raining Darkness bringing Pure Ruination): The second and final extension of Shade Forge: Discalibur, Extension: Discalibur – Absolute Domination is a serial of seventeen slashing attacks that end with the complete eradication of the opponent, though it can be extended to grant an additional hit. In any case, when performing Extension: Discalibur – Absolute Domination, the caster activates Shade Forge by going to the extremes of the 'magic = feelings' concept— by fuelling this magic with negative feelings, the user of Black Dragon Slayer Magic is capable of initiating the usual fusion of eternano and magical power, but only manifesting their magical powers in a dark and malefic nature while drawing any source of darkness towards them, before they utilize their imagination in order to mold the darkness and shadows created through Shade Forge into the form of two single-edged swords; shadows scatter off of both weapons in this state. Once both Discaliburs have been formed, the caster surges their magical energy upwards to unleash a jet-burst thrice the potency of when they move normally, resulting in a rocket boost that blasts the user towards the opponent in the blink of an eye; transcending such concepts as 'evasion', 'defense', and 'countering'. Catching the foe off-guard, the user begins their assault by slashing the enemy from all directions as the speed of their slashes gradually increases, becoming quicker and more furious with each strike; each blow results in darkness erupting from the corresponding blade to cause extra damage, also having the side-effect of causing a dark sphere that blackens the area for the briefest of moments- the flurry of strikes pierce the enemy's Magic Pathways, thus resulting in the enemy having no actual way to defend against the final strike. After several slashes, the user dashes through the enemy with a single, two-handed powerful strike that is near-impossible to react to, attacking with enough force to split the earth, pierce the skies, and part the seas- it's much less a "final attack" as it is a force of nature being brought down upon their bodies, dealing overwhelming damage and blasting the opponent away. There are seventeen strikes in this deadly combo, with sixteen being the flurry of steel and the final serving as the coup de grace. Extension: Discalibur – Absolute Domination also has an extension- while unnamed, after the final strike of the initial combo, the user leaps into the air, aiming down at the opponent before slashing with both swords in an overhead swing, unleashing two blast spells at once which raze the ground near the opponent while exposing the enemy to the sheer intensity of the darkness released by the projectile upon impact which is capable of wiping out almost anything it its path.

Advanced Spells
Dragon Slayer's Secret Art (滅竜奥義, Metsu Ryū Ōgi): The strongest techniques of a Dragon Slayer.
 * Black Lotus: Slashing Shadow Array (黒蓮・斬影陣, Kokuren: Zan'eijin): TBA
 * Jörmungandr: Eternal Requiem (, Yorumungando: Etānaru Rekuiemu lit. Serpent's Maw Divine Return: Thousand Souls Dark Branding): Jörmungandr: Eternal Requiem is one of Níðhöggr's two Dragon Slayer's Secret Arts, the strongest techniques of a Dragon Slayer; in the case of this spell, Jörmungandr: Eternal Requiem creates a pulsing crimson wave of shadow that cancels out all power-ups currently activated while dealing serious damage. When performing Jörmungandr: Eternal Requiem, Níðhöggr gathers and compresses magical energy from the vicinity upon one of his claws before he takes the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, Níðhöggr induces the usual fusion of eternano and magical power, but only manifesting his magical powers in a dark and malefic nature while drawing any source of darkness towards him while focusing it around his hand, compressing it completely to the point that it can be visually described as specks of crimson and black molting off of his large claw like they were feathers; however, from here, the Black Dragon thins out the energy focused on his claw in order to result in not an overwhelming amount, but not a miniscule amount either; essentially, it is just the right amount; at least to oppose the foe's offending spell—it calls upon the theory of Mao-Dun in order to function. The Mao-Dun theory concerns a blacksmith who makes both shields and spears. He first pitches a customer the spears, claiming that they are so sharp, no shield can block them. He then pitches the shields, saying they are so hard, no spear can pierce them. The customer then asks what would happen if he threw one of the blacksmith's spears at one of his shields...and received no answer. This is the source of the Chinese word for paradox (矛盾, máodùn lit. spear-shield). The darkness collection in the Black Dragon's hand is concentrated to a single point; and with a single throwing motion, Níðhöggr launches the collection of darkness forward in the form of a spiralling pulsing horizontal shockwave of crimson darkness that barrels through the opposing collection of supernatural particles that composes the offending supernatural powers, causing everything else to be shoved aside into fragments of shadow, essentially breaking it into pieces, nullifying the enemy's supernatural abilities and negating their supernatural powers at the point of contact while producing enough force to blow the opponent away.
 * Jörmungandr: Damned Charging Lance (, Yorumungando: Damudo Chājingu Ransu lit. Serpent's Maw Divine Return: The Tyrannical Soul-Sucking Spear of Absolute Darkness Bombardment): Jörmungandr: Damned Charging Lance is the name of Níðhöggr's only Dragon Slayer's Secret Art and his absolute strongest attack. However, the end result of the attack is unknown, as Ashur was capable of stopping it and countering with her own Secret Art, Ultimate Ascension Wave. As the name and the rest of Black Dragon Slayer Magic's power would suggest, it could destroy everyone nearby. It was said that this was the move that was used to defeat Ashur the first time. However, in Daybreak S2, Damned Charging Lance is finally utilized – more than living up to its potency. When activating Damned Charging Lance, Níðhöggr activates his Black Dragon Slayer Magic by taking the 'magic = feelings' concept to the fullest—by fuelling this magic with negative feelings, Níðhöggr  is capable of initiating the usual fusion of eternano and magical power, but only manifesting his magical powers in a dark and malefic nature while drawing any source of darkness towards him, gathering and condensing darkness around his body momentarily as it flows out and around his large frame, obscuring everything and anything as day turns into night with blood red fog while darkness pulsates throughout the atmosphere, followed by Níðhöggr's words, "Let me show you fear and despair..." (恐怖と絶望を味わってみよ… Kyoufu to zetsubou wo ajiwattemiyo...). The blood red fog and darkness shrouding the vicinity intensifies as vicious winds are stirred up, signifying the absolute hell that is about to be unleashed on earth. With the crimson skies glowing above, Níðhöggr lets out a mighty roar - this gesture acts as a conduit which focuses and dictates the flow of magical energy, tapping into the magical energies that already exist within the earth and matter; representing the cyclical flow of eternano and turns that power to manipulable ends; allowing the Black Dragon to mold and initiate the fusion of magical energy- however, as per the usual aspects of Black Dragon Slayer Magic, the magical energies brought into this plane of existence are a darker shade of energy that is an embodiment of sheer, unrelenting hatred that manifests a serial of dark red and black ethereal spears from thin air using the above mentioned process- the lances possess long and hollow concave edges, with a cross-shaped "handle" and a diamond-shaped gap in the center. The "handle" is connected to a guard that has two spikes on either side of sorts that is an extension of the sides of the blade. Floating around Níðhöggr in a circular formation at high speeds, the Black Dragon then mentally commands the lances to shoot towards his opponent; causing the spears to expand while surging forth in the blink of an eye, tainted a pulsating raven as bleeding scarlet discharges of electricity arc around the spears. All these volley of spears dart through the air, they create a gravitational field around themselves which possesses immense attraction force, drawing in everything in the vicinity including ambient supernatural energies that are suspended within the atmosphere, gradually getting larger, as well as growing stronger and stronger and faster- the almost magnetic pull never ceases, only becoming more and more powerful as moments pass. Not only this, as pure shadows influenced by Black Dragon Slayer Magic, it possesses an immense corroding influence, as anything that that any Damned Charging Lance passes by is instantly disintegrated into nothingness, eradicating anything upon contact by busting it into numerous black cubes of shadow. The Damned Charging Lance effect is not only a relentless attack, but Níðhöggr possesses pinpoint control over the spell, and his unerring aim allows the lances of destruction to travel in straight lines or bend, twist or curve around corners; upon impact, and everything inside the Damned Charging Lance's blast radius is devastated, while nothing outside of it is even touched; tsunamis, shockwaves, and ring clouds form for every living second that the spell is in motion. Upon contact with the attack's target, the lances induce nuclear fission through sheer evil upon the masses of particles in the vicinity, breaking the particles apart with the process of a nucleus of eternano splitting into smaller nuclei in the blink of an eye, releasing a quantity of energy unheard of in any day and age in the form of an enormous explosion that echoes outwards for several thousand kilometers or more, the impact of the powerful surge causes a large mushroom cloud of darkness to quickly rise upwards at the point of casting the spell.

Trivia

 * Just like how Níðhöggr is meant to be the Sun Trilogy version of, Black Dragon Slayer Magic is partially based off of Acnologia's form of , or rather, what's known about it so far.
