Spirit Slayer Magic

Spirit Slayer Magic (滅霊魔法, Metsurei Mahō) is a Caster Magic, Lost Magic, and finally, a subsection of the Slayer Magic line that grants the wielders of its power the ability to transform the physiology of their body into a spirit, an extremely powerful type of legendary creature that's classified non-corporeal substance contrasted with the material body; this includes those brought into the physical realm through the power of other magicians such as Celestial Spirits, Familiar Spirits, Planetary Spirits, Elemenian Spirits, Virago Spirits, and possibly many more, but also encompasses a wide variety of terms, including ghosts and sprites. Spirit Slayer is known to be a rare magic even for Lost Magic standards, perhaps even rarer than Devil Slayer Magic, Demon Slayer Magic, or God Slayer Magic at least on par with Dragon Slayer Magic in terms of elusiveness.

Following the closure of the that was waged between s and Humans, along with the reign of  ending, a select few wielders of Spirit Summoning Magic of all kinds wished to take over the world with their relatively unknown power being reportedly superior to that of others. To this extent, these magicians had begun to conjure spirits themselves using their own magic to do so. Sensing this uneven distribution in supernatural entities, the, along with the ruler of the Familiar Spirits and other spiritual entities began to, in a similar manner to Dragons, teach Humans their ways of combat in order to neutralize this uprising; because of this, Spirit Slayer is one of the "newer" types of Slayer Magic. Just like how users of Dragon Slayer Magic are referred to as s, the wielders of Spirit Slayer Magic, trained to hunt and destroy these otherworldly beings, are referred to as Spirit Slayers (, Supiritto Sureiyā lit. Spirit Destroying Magician).

Description
In order to learn the power of Spirit Slayer Magic in the first place, the beginning stages of obtaining its power takes place in a similar manner to a wielder of First Generation Dragon Slayer Magic; being taught by a spirit itself; of course, it doesn't matter what kind of spirit it is, as long as it can be classified as "an incorporeal body with an existence composed entirely out of energy" as per most forms of spirits. A willing user can learn Spirit Slayer Magic from almost any type of spirit, as long as the spirit in question has the methods in order to teach the magician; though "Spirit Kings"; leaders of a spirit race cannot teach a magician, as if they were to attempt to teach a human their magic, they would be unable to accept the force of their magic. Once a hopeful wielder of this incredible power has decided what spirit to have them teach this magic, the caster must forge a contract with spirits of any type, even ghouls hailed as Summon Spirits which are located within the world of —usually one per town. These beings are part of a set created by the 'higher spirits' for the sole purpose of keeping order within Earth Land. First, the foremost requirement is to locate a spirit. Finding one isn't a walk in the park, that's for sure- the user must be knowledgeable in its habitat, its favorite kind of food, and what it wishes to make out of the contract. From here, the spirit and the caster work out a suitable deal with the target commonly asking for their heart's desire and the user asking for something important to the target in return; but once the deal has been completed, the spirit expels their supernatural energies outwards, engulfing the target in their malefic supernatural powers which seep into the target's body, reaching their soul itself in a ritualistic process. From here, the spirit utilizes their mastery over the arcane and the supernatural particles that are strewn about through this world of whimsy and wonder, engulfing the hopeful wielder with their arcane energies as they seep inside of the target's body, with the spirit reaching inside the humanoid's soul, searching for that otherworldly organ referred to as a Magic Origin and from there, making a few changes here and there as to alter the process of how the Magic Origin functions and its properties, therefore transmogrifying their Magic Origin into a strange hybrid between that of a spirit's Magic Origin and a humanoid Magic Origin, possessing the traits of the former but the arcane storage capacity of the latter, effectively causing their body to be bestowed with the magical powers of a Spirit - otherwise known as Spirit Slayer Magic. Continuing with this process, this magical power acts alongside the energy of the body in order to catalyze a variety of bodily processes, therefore allowing the morphing of their physiology to a point where the individual has adopted some physical traits, a myriad of abilities also shared with their teacher, as well as the element from the said spirit, which can be conjured from the magician's body for countless purposes; upon teaching the magician their form of Spirit Slayer Magic, the spirit enters the caster's soul in a manner not dissimilar to the Dragon Soul Seal and engraves their powers within the wielder, constantly boosting Spirit Slayer Magic to a level akin to Primal Dragon Mode. As one may notice, Spirit Slayer's mechanics are extremely similar to that of any other Slayer Magic; however, there's more than meets the eye.

These changes in their biological traits and structure range from rather unnoticeable things such as enhanced senses, which are a physiological capacity of organisms that provides data for perception, such as olfaction to the point that they can smell blood on a shirt even if it's been through the dry-cleaners or discover a forest fire even from several thousand kilometers away, audioception, which grants them a minor form of extra-sensory perception that allows them to detect movements through a form of clairvoyance, and ophthalmoception, bestowing upon the wielder of Phoenix Slayer Magic the ability to see things with pin-point accuracy even if it's a fair distance away and gain a form of night vision, allowing them to see in low light conditions. While this is all standard for a Slayer Magic, Spirit Slayer Magic also bestows upon its wielder the perpetually available ability of channeling the powers of other spirits, with the caster working as a medium, which is the practice of certain people—known as mediums—to purportedly mediate communication between spirits of the dead and living human beings; this allows them to not only talk to souls which wander around the world in a manner not dissimilar to and gain their strength, but also, by voluntary choice, allow others to do so as well as long as the third party is in direct contact with the wielder of Spirit Slayer Magic. Through their connection with the spirits, they are capable of summoning various spirits to do their bidding, with their etheral beings acting as spirit guides. Despite the boons bestowed upon the user, those traits above can be said to simply be side-effects of having the physiology of a spirit; indeed, the greatest ability of a wielder of Spirit Slayer Magic is also its signature power – calling upon the assets of a spirit 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 spirit instantaneously which is done in conjunction with the activation sequence of their particular element, bestowing upon the user of Spirit Slayer Magic; spiritual lungs and enhanced vocal folds that are capable of spewing elemental energies, a corporal body that's laced with elemental energies as to provide protection against said element, and fierce limbs, whether prehensile or not which are enshrouded with elemental energies, specifically attuned to dealing incredible amounts of damage; though unlike most forms of Slayer Magic, these traits are highly variable depending on the spirit whom taught the wielder, as spirits come in all shapes and sizes.

All of this combined, results in the physiology of a Spirit Slayer transforming their entire existence into that of a make-shift weapon whose ownership is unique to them and them alone, wielding the element harnessed by their spirit and passed down to them alongside the natural physical superiority of a spirit 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 Spirit Slayer Magic usually shines thanks to the overwhelming physical might of a spirit. The form of Elemental Magic that the wielder of Spirit Slayer Magic commands, whether it be one of the classical elements, which are the rudimentary, simplest or essential parts/principles of which nature consists and were proposed to explain the nature and complexity of all matter in terms of simpler substances or something more abstract is theirs to command and at its absolute strongest when harnessed by a Spirit Slayer. Unlike its cousin, Dragon Slayer Magic, Spirit Slayer Magic is not the only known way to slay a spiritual being, though it is, without a doubt, the most effective method as it turns the spirit's advantages on them. Unlike other forms of Slayer Magic, while Spirit Slayer styles are indeed classified as elements, Spirit Slayer Magic has yet another function- certain spirits can teach the user more abstract concepts which naturally accompany the element - ranging from phenomenon such as sound waves to abstract powers such as emotions. This is not solely restricted to elements though, as not only elemental-oriented spirits can teach it; meaning that there are many possibilities for the style, as even unorthodox aspects can be manifested, such as emotions and mimicry. These traits don't encompass full magics by themselves, but rather, they're part and parcel of the powers bestowed upon the Spirit Slayer by their spirit; thanks to a highly variable interpretation of what it is to be a spirit, a wielder of Spirit Slayer Magic is capable of becoming intangible, elemental-wise or not, for brief periods of time, effectively inducing invisibility, which is the state of an object that cannot be seen.

As per its nature as a Slayer Magic, a wielder of Spirit Slayer Magic has absolute dominance over any form of their element, and as such, a wielder can control their respective elements that are not generated from their own Magic Origin, but are already preexisting within the environment; this is achieved through intense mental focus and the mere act of having the element that's brought into existence through their magic wash over the preexisting source, causing the affected area to have its coding modified to obey the will of the caster, thus bolstering their already incredible power to higher and more versatile levels – a good example of this is how a user of an air-inclined Spirit Slayer Magic if geared towards offense like its subspecies, is able to shift the atmospheric air in order to suffocate their opponents. Not only this, any other form of the wielder's specific Elemental Magic, if it isn't from another user of Slayer Magic or a greater magic manipulator than the Spirit Slayer whom would naturally take precaution and add in countermeasures, is immediately put under their thrall, and even if the user simply doesn't absorb it, a Spirit Slayer Magic is able to smother the elemental energies and using their eternano and magical makeup in order to increase the speed, power, and scope of the currently manifested spell. To the extremes, a Spirit Slayer is capable of incorporating the activation sequence of Elemental Body ability of Elemental Magic into their form of Spirit Slayer Magic, integrating their element into their very existence, absorbing their element into their flesh and fusing it with their body as to undergo a full-body transformation into said element; they can change their physiology into their element either partly, or completely. Doing so offers the user of Spirit Slayer Magic something akin to nigh-invulnerability, as they can be damaged in almost any way imaginable such as being shattered, split into numerous pieces or dissipated - but as long as the user of Spirit Slayer Magic is in their elemental form, they are capable of reforming their bodies without injury with physical-based attacks simply passing through their corporal form. A Spirit Slayer's Magic Origin automatically and unconsciously draws in elemental energy of the user's attuned power with every second that it is active, effectively rendering elemental magicians useless; in addition, it also absorbs natural sources of their element, with a Water Spirit Slayer Magic user being capable of absorbing small lakes and a Fire Spirit Slayer can put out fires simply by walking into the source; though, in more extreme cases, a Spirit Slayer is incapable of absorbing too much of their element at a time due to risk of magic overload.

Indeed, as one may have guessed from the name of this Slayer Magic, the purpose of Spirit Slayer Magic is to slay the existence referred to as spirits, and thus, the absolute greatest advantage that Spirit Slayer Magic has over the other Slayer Magics is that, unlike many other Slayer Magics, Spirit Slayer Magic can be utilized to kill all sorts of spirits, whether they be "summon beasts" (召喚獣, Shōkanjū), such as Celestial Spirits, Elemenian Spirits, Virago Spirits, spirits who dwell in the atmosphere, souls of the departed, sprites, and even some demons and countless others as the term "spirit" is known to encompass a wide variety of terms, only loosely categorized as "doesn't fit in other races but definitely isn't human, also ghost as fuck". Thus, the wielder of Spirit Slayer Magic has their attack and defensive power massively boosted against everything that can be considered to belong to the race of spirits - indeed, as the term "spirit" is open to a vast amount of interpretation, in a manner similar to Devil Slayer Magic, Spirit Slayer Magic could be considered a rare gem in that it can be categorized as an extremely rare and powerful type of subcategory of magic known as a Semantic-Type (意味型, Imi-gata), meaning that it is a supernatural power that can be defined solely by the caster's interpretation of what it governs over, all depending on their wording rather than anything logical—because of this, Spirit Slayer Magic can theoretically affect anything that constitutes a "spirit", allowing for a great deal of stretching of what it is capable of. In that manner, Spirit Slayer Magic could be considered a power akin to that of Memory-Make or Arc of Embodiment, in all three heavily rely on the caster's imagination in order to bring out its full potential- while the former two are simply confined to using the power of creation to forge objects and attacks from the magician's thoughts to do battle, Spirit Slayer Magic is only limited by the creativity of the caster, as mentioned before, anything that can be referred to as a "spirit" causes their maneuvers to power up; indeed, this simple concept can be applied to a near countless multitude of unconventional uses as to almost give a Spirit Slayer a distinct advantage in any situation. However, despite all these overwhelming advantages that Spirit Slayer Magic has over the others, it more than makes up for these disadvantages with a rather awkward set-up. By itself, at the start of a battle, Spirit Slayer Magic has little to no offensive pressure and not much in the defense department either; while Spirit Slayer does function in a similar manner to that of a normal Slayer Magic, a fair amount of their moves are situational at best; and they cannot activate their stronger forms and abilities from the get-go. However, with every usage of their magic, the spirit-modified Magic Origin of the user fills up, whether it be from landing a successful hit or from absorbing/negating a foe's attack; once it is completely filled, the wielder of Spirit Slayer Magic is capable of activating Trance; which drastically increases the power of their attacks, slowly regenerate their stamina and magical power, and grants them an enormous boost in power. However, the Magic Origin empties gradually as the user fights, lasting ten minutes; and accessing their full power also decreases the amount of magical power within the Magic Origin as while also emptying naturally; making this a difficult to master magic, but devastating when applied correctly.

Through an ingrained part of Spirit Slayer Magic that's something unlike any other form of Slayer Magic known as Slayer Imitation (, Sureiyā Imitēshon lit. Spirit Property: Slayer Magic Replication) depending on the spirit that taught the wielder of Spirit Slayer Magic their particular magic, a wielder of Slayer Magic is capable of inducing a peculiar style of mimicry, which is a similarity of one species to another that protects one or both in evolutionary biology, with the arcane patterns of the caster's Spirit Slayer Magic evolving to share perceived characteristics with another Slayer Magic by copying the processes and mechanics of another form of Slayer Magic perfectly. However, as one may have guessed, Slayer Imitation only applies to select forms of Spirit Slayer Magic that have an association with particular spirits - for example, the known as Draco, whom represents the same-named constellation in the far northern sky, if teaching a hopeful wielder of the magic their Spirit Slayer Magic, since "Draco" is Latin for "dragon" and thus heavily associated with dragons, a legendary creature that's scaled or fire-spewing; with serpentine, reptilian and avian traits, the Spirit Slayer Magic will contain a single property of Dragon Slayer Magic that depends on the spirit's whims; this sole property will be permanently active and accessible along the numerous other properties of Spirit Slayer Magic, giving this form of Spirit Slayer Magic a little extra oomph when compared to other forms of Spirit Slayer Magic. Another example of this is a theoretical Spirit Summoning Magic that represents the Eastern Zodiac, a classification scheme that assigns an animal to each year in a repeating twelve-year cycle, with its dragon teaching the user the Spirit Slayer Magic. It's said individual properties from all forms of Slayer Magic are capable of being replicated with this trait of Spirit Slayer Magic, leading to countless options. Because of this, it's generally recommended that a hopeful wielder of Spirit Slayer Magic chooses the spirit to learn their magic from wisely as some forms of Spirit Slayer Magic are inherently stronger than others. Going by the interpretations of what Spirit Slayer Magic is known to be able to effect, it's said that as long as it's classified as a "spirit", the caster is capable of learning their magic from it. On a completely unrelated note, a wielder of Spirit Slayer Magic is able to shape their element in a manner akin to Molding Magic by using Shape Transformation on the element manifested as to forge it in the shape of constructs, which can be utilized in various manners, these tools and familiars used for offense and defensive maneuvers to keep the opponent on their feet.

Like all Slayer Magics, the spells of Spirit Slayer Magic follow a specific naming pattern; it is formatted "[Element] [Spirit]'s [Attack Name]" (_霊の, _rei no_). These "normal" spells more often than not have the caster inducing their spirit teacher's power by integrating it into their body in order to bolster their close-combat abilities with some mid-ranged attacks thrown into the mixture, forming a powerful "spear and cannon" combo, granting them notable versatility. Generally, a Spirit Slayer's arsenal of spells varies from user to user, as even though some Spirit Slayers have the same element, their spirit teacher is more often than not a being different than another magician's, resulting in a completely different fighting style; because of this, the variations are known to be almost endless. Once a Spirit Slayer activates the magic-amplification technique known as Trance, it becomes certain that Spirit Slayer is on a completely different level than other Slayer Magics. When the Trance spell is engaged, the user gains access to a fiery aura and more importantly, completely new spells that blow the previous ones out of the water. These spells, while still focused around the Spirit Slayer's element, have been intensified to the point that they cannot be devoured by another Slayer Magician of any kind unless certain, vaguely-defined precautions are taken, and even then, more often than not, consuming the user's element in this state is ill-advised as it tends to explode if others try. The spells that the user is capable of harnessing do not follow the normal Slayer Magic naming pattern; instead, their titles vary from user to user. Of course, like every other Slayer Magic, a Spirit Slayer has access to "finishing moves", the advanced spells of a Spirit Slayer are known as Spirit Slayer's Secret Arts (滅霊奥義, Metsurei Ōgi); which are generally much more powerful than basic techniques. All Spirit Slayer's Secret Arts boast overwhelming power, being dubbed the "ultimate spear" of a Spirit Slayer; however, they usually cost a large amount of magical energy to properly cast. However, in addition to these "finishing moves", when in any powered up state, a Spirit Slayer can harness Oversoul Arts (, Ōbasōru Āto lit. Spirit Slayer's Revised Secret Arts), which are further enhanced to the point that it is said that even the weakest spell can smash through anything unfortunate enough to be in its path.

Indeed, Spirit Slayer Slayer Magic has virtually unlimited customization options in regards to the element formed through simple magical manipulation and reinforced through the power of a spirit – the colour of the element is able to be altered freely, its properties which aren't limited to 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; the type of damage that the element inflicts upon anything that it comes into contact with is able to be changed at will such as a fire-inclined Spirit Slayer Magic changing from inflicting "blunt" damage that feels like being hit with a sledgehammer to a stream that burns anything in its path through inducing a minor form of phase transition as to grant it corporality and switch back. Of course, as the highest form of elemental manipulation around, a wielder of Spirit Slayer Magic is capable of harnessing their magic in any manner that they deem to be suitable, commonly changing between offensive, defensive, evasive, or supplementary potencies in accordance to the situation at hand; but generally, as long as the Spirit Slayer is able to imagine their element being used in a particular manner and it doesn't break the laws of physics or conflict with any established limitations, then the sky is the limit, more or less. As per the nature of Slayer Magic, a wielder of Spirit Slayer Magic is known to be immune to the effects of their own element, and can consume external sources of their element to replenish their strength, both stamina-wise and magic-wise. They are also naturally immune to the effects of their own element that came from both their own person and to those from other sources, but must consume it through their mouths if they are to actually absorb it into their bodies - a Spirit Slayer cannot consume the element that they produce themselves; however, unlike other Slayer Magics, a Spirit Slayer's magic shall absorb any trace of that element in the immediate vicinity, and/or use the correct chemical reactions in order to produce the element continuously. It should be taken into consideration that Spirit Slayer Magic also bestows upon the wielder immunity to effects related to their elements as well. For example, a user of a fire-inclined Spirit Slayer Magic is unaffected by various temperatures as their body heat is constantly regulated thanks to their magic.

Common Spells

 * Trance (, Toransu lit. Mysterious Spirit Ethereal Power Amplification): Trance, formerly referred to as Geist Charge (, Gaisuto Chāji lit. Spiritual Awakening State), is an uncategorized Spirit Slayer Magic spell that's an Magic-amplification technique and equivalent to Dragon Slayer Magic's Drive; Trance brings out the true power of their capabilities as a user of Spirit Slayer Magic, excluding the power boost granted by Spirit Force, yet, at the same time, seemingly enhancing the user's physical prowess to a rather extreme degree. Indeed, as there's only one generation of Spirit Slayer Magic so to speak, unlike its draconic equivalent, Drive, which is exclusive to Third-Generation Dragon Slayers, due to Spirit Slayer Magic being incompatible with Lacrima, the magic crystalline substance found on both and  which can be used to implant various forms of magic, Trance is known to be capable of being harnessed by any user of Spirit Slayer Magic as long as they possess the power necessary to induce its effects and the knowledge of how to do so. When invoking the power of Trance, the caster focuses the energies that are dwelling within them frame intently, as they begin to surge the arcane powers within themselves outwards while inducing the activation sequence of their particular element; from here, after obtaining enough magical power to transform, the wielder of Spirit Slayer Magic focuses their magical power, establishing a connection with their spirit teacher, no matter the distance between the two and the dimensional differences before the magician summons their spirit teacher to the current dimension using their spiritual link. Once this is done, the user utilizes their spiritually-attuned Magic Origin as a medium for their spirit teacher, whom 'overlays' their magical power over their student, combining the two, actualizing the knowledge and memories of an apparition, granting the user an enormous boost in power, more often than not engaging in a physical change. The augments on the Spirit Slayer's body are composed entirely of magical energy and being so, there is no actual matter. While any spirit can be molded into any shape or form the magician desires when their student uses Trance, their attributes depend solely upon the spirit's attributes. Activating Trance increases 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 their element cloaks around them. While in this state, the user demonstrates heightened reflexes and extremely quick information processing, and it amplifies the powers of their Spirit Slayer Magic without exhausting themselves. This state grants the user the ability to perform new spells; as well as making their pre-existing spells far more powerful, though the power boost granted by activating Trance is proportionate the amount of magical energy used to link student and teacher, as well as the magician's level of concentration. Generally speaking, the form granted by Trance can be divided into four categories, which are as following; Attack-Type (, Atakku Taipu lit. Offensive Type), which is the most common of the Trance types- even though they are considered 'generic', they are easily the strongest, albeit not the most flexible; Attack-Types normally take the form of offensive-based weaponry, such as swords, guns, spears, hammers, and many more. The Attack-Type focuses solely on sheer brute force or overwhelming attack power, the Manifesto-Type (, Manifesuto Taipu lit. Ghost Puppet Type), which is slightly rarer, though it is relatively easy to get ahold of; it's a Trance in the form of the user's elemental power that is manifested in a physical form that acts on its own. Because of this, the user does not need to lift a finger to strike; their elemental energy will do it for them. While the Manifesto-Type resembles any sort of summoning magic, it's an extension of the user rather than a separate entity; the Manifesto-Type hovers around the Spirit Slayer in a similar manner to that of a wraith; hovering behind and above the user while usually being invisible to those unaware of them. The Manifesto-Type can attack in tandem with the user, bolstering their strength significantly while working as a medium to cast higher-powered spells. Other forms that Trance are capable of taking upon are Supplement-Type (, Sapurimento Taipu lit. Support Type) is slightly rarer than both Attack-Type and Manifesto-Type, though it is relatively easy to get ahold of. As the name indicates, the Supplement-Type has a Trance in the form of shields and other defensive armaments. The abilities exhibited by Supplement-Types are generally geared around shielding and the like- in addition, they can be used for numerous other tasks. It should be taken into consideration that in terms of special abilities, a Supplement-Type can possess such powers as augmenting magic, healing, firing elemental blasts, manipulating aspects of the mortal plane, and many more. Lastly, the final type is known as the Clad-Type (, Kuraddo Taipu; lit. Full Armour Type), which is the most elusive of the Trances - as the name indicates, the Clad-Type results in the spirit teacher forming a full body armour to encase the wielder's body in; essentially shrouding their form in power. This provides a significant increase in speed, strength, and durability, in addition to the ability to replicate the spirit's personalized abilities to a smaller extent. The Clad-Type, because of this, is regarded as an all-rounder between the Attack-Type and the Supplement-Type. As a side note, the Grimoire Five (, Gurimoa Faibu lit. Five Great Elemental Embodiment Colossus Defenders) are the strongest of their kind, and well, as the designation would indicate, the Grimoire Five are Manifesto-Type Trances whom are an embodiment of the five fundamental elements of nature. They are known to manifest only in exceptionally powerful and determined individuals, with, as their sub-name would indicate, there only being five in existence- once a previous owner dies, their Trance will reincarnate in somebody else. The power of the group is unmatched by any other Trance type and even summon spirit, except for spirit king-class beings. They have the ability to consume their element to further enhance their own power; this can be from any source, such as Lost Magic and Slayer Magic. Strictly speaking in terms of practicality, the classification of the user's Trance isn't a complete indication of its power, meaning that the effectiveness of a Trance form is largely based on the magician's own preferences. Additionally, like other forms of Slayer Magic amplification-type spells, the uprise of magical energy could easily obliterate the user or severely damage their body, if harnessed for too long.

Spirit Force
Spirit Force (, Supiritto Fōsu lit. Spirit's Power) is the most advanced state that an ordinary Spirit Slayer is capable of taking upon - it can be seen as the equivalent to Dragon Slayer Magic's Dragon Force in that both are powered-up forms that amplifies their prowess all across the board by tenfold the amount and essentially transform the wielder of the Slayer Magic into the creature their magic was created to kill in the first place. When a Spirit Slayer enters Spirit Force, they effectively turn into a miniaturized, humanoid form of the spirit that taught them their Spirit Slayer Magic, resulting in the Spirit Slayer undergoing a rather major physiological change, resulting in the caster gaining traits that are associated with the spirit, which means the change is highly variable, but some common alterations include wings of elemental energy growing from numerous portions of their body, which is usually from their back, as well as a variety of runic patterns becoming automatically engraved across their frame. However, as their power grows, a Spirit Slayer in Spirit Force will fully transform into a perfect replica of their spirit, no matter the size.

In this state, all of their physical attributes are bolstered enormously, making them far stronger, more resistant to damage, and faster; the Spirit Slayer now has access to upgrades or even additions to their normal abilities like flying or hovering; spell-wise, a Spirit Slayer in Spirit Force is capable of utilizing more advanced, powerful attacks, and the transformation enhances all of the user's regular spells, greatly increasing their area-of-effect as well as improving their damage significantly. Tapping into this power which is said to be the "true power of a Spirit Slayer" also drastically enhances the user's physical prowess, making them far stronger, more resistant to damage, and faster, to the point that with Spirit Force activated, the caster's strength and speed have increased to the point that they are able to punch an with enough force to shatter their body by just having their fist come into contact with the artificial devil while sending the demon careening across the landscape, knowing them down the road with little effort in doing so. Their strength has been enhanced to the point that with a simple clap of their hands, the caster is capable of manifesting a violent tremor that obliterates the ground it comes into contact with and knock their foes away; in addition, the strikes unleashed both unarmed and with a weapon are positively overwhelming and can be bone-shattering. The sudden boost in strength upon activating the form allows the caster to break free of binding-type spells which would normally restrict their bodies and impair their movements through nothing but sheer force of will. With Spirit Force, the caster can grab a blade with their bare hand without feeling any of the exerted force, though said force could do considerable damage to the surrounding area. In addition, their endurance has been upped significantly; enabling them to receive damage like it was nothing and ignore all senses of pain—though it should be noted that this varies on the factor of how powerful the blow is. Finally, the user's naturally immense swiftness is augmented to the point that they can forgo any need for speed-enhancing techniques, enabling them to outstrip almost anyone in a contest of pure speed. Spirit Force increases the user's moving pace to one high enough where simple melee attacks can have great power, a Spirit Slayer using Spirit Force the ability to move at a rate of acceleration and maximum speed in excess to that of normal optimal human capacity. With their speed, the user has plucked an arrow out of the air from a standing start, and has dodged machine gun fire; and the user has created cyclone-like gusts of wind regardless of their actual element, which are able to knock a hoarde of wyverns off of their feet.

While in this state, a user of Spirit Slayer Magic demonstrates heightened reflexes and extremely quick information processing, and it amplifies the powers of their signature magic without exhausting themselves; activating the skill, however, has a notable amount of startup invincibility by using the boost in magical energy gained by invoking its power as a rippling aura that shrouds their body from all conceivable directions while inducing a similar effect to Nullification Magic as it renders anything and everything that could count as doing damage to the caster null and void by reversing the energy output and freezing the motion of the energies, so if the caster's opponent is attacking them while they are activating the skill, the caster will be capable of counterattacking immediately as to turn the tides instantly. Activating Spirit Force results in a rather considerable amplification of the magical power dwelling within the body of the user, causing the energies and the caster's Magic Origin to effortlessly replicate the magical energies and the Magic Origin of the phantasmal crpytid that taught them everything they know about fighting like a spirit, causing the powers exuded by their body to reach critical levels in both output and potency, thus causing their magical energies to take upon a violent corporeality fashioned into the visage of an actual spirit that, when exuded at its fullest potential, becomes visible and begins to interact with all sorts of particles that are saturated throughout the atmosphere, causing a multitude of chemical reactions in regards to what's compatible with their element - for example, a user of a fire-inclined Spirit Slayer Magic will have their flames superheat the surrounding air; the heating of the air causes the particles to split due to reactions; thus causing a combustion with the atoms of hydrogen to induce a serial of explosions that they can shape in any way that they wish; this also allows the user to let physical and magical attacks pass harmlessly through their body when they're transformed, with their structural makeup transmogrifying into that of their element more or less. As the Spirit Slayer Magic user's entire body turns into their element, after activating Spirit Force they are virtually immune to physical harm; they can allow any attack to simply pass through them or simply absorb the attack. Activating Spirit Force also allows the user to constantly absorb magical energy and ambient eternano suspended within the atmosphere and convert it into their element, further boosting their power- this ability also works on the foe's magical power and element, but only if it is the same type of element in the latter case. For a Spirit Slayer to activate Spirit Force, they must absorb a large amount of magical power attuned to their element; after this is done, they can activate it at will without any drawbacks, though in all forms, Spirit Force consumes a large amount of the user's magical power. Spirit Slayers who have had Eclipsed Spirits for teachers are capable of using an enhanced version of Spirit Force referred to as Eclipse Force (, Ekuripusu Fōsu lit. Spirit's Power: Tainted Spirit Revision).

Common Abilities

 * Dual-Element Spirit Mode (モード二要素霊, Mōdo Niyōrei): Dual-Element Spirit Mode is a Spirit Slayer Magic ability that virtually all wielders of Spirit Slayer Magic are capable of utilizing, and as the name would indicate, it is the Spirit Slayer Magic equivalent to the likes of of Dragon Slayer Magic, Dual-Element Devil Mode of Devil Slayer Magic, and Dual-Element God Mode of God Slayer Magic in that it is a state where a Spirit Slayer consumes the element of another Spirit Slayer Magic and combines both elements into one inside their bodies and use them to increase their abilities through the filtering and domination of the harmful aspects of the consumed element by way of the caster's Magical Aura as to momentarily dilute its hazardous effects to enable the consumption to take place, allowing the Spirit Slayer to integrate this element within their Magic Origin, making it safe before their flare its power up once, thus allowing the wielder of Spirit Slayer Magic to channel and harness both elements inside of their bodies whether it be separately or combined in a manner that's uncannily similar to a Combination Spell, which is, well a combination between two magics, not dissimilar to that of a Unison Raid as to create a power that's not dissimilar to invoking the power of Spirit Force; as well as drastically increasing their own destructive capabilities. As a result of the sheer volume of the magical power granted by this power-up, before even properly utilizing the power to its fullest, the user constantly discharges aftereffects of their element, and their speed and power drastically increase to levels that allow them to fight toe-to-toe with incredulously powerful beings- the power of Dual-Element Spirit Mode can also enable them to shrug off some forms of . When in this form, the user has access to enhanced versions of their normal Spirit Slayer Magic spells. When the power granted by Dual Element Spirit Mode is exerted to its maximum, in a radius expanding meters, the surroundings itself becomes a storm of dual-streamed elemental energy which varies from user to user, and the user becomes cloaked in their element, which takes upon the manifestation of the spirit whom tutored them in this magic, causing a frightening visage. Additionally, depending on the two elements combined, the wielder, while Dual-Element Spirit Mode is invoked, is capable of of merging the effects to produce an entirely new result, such as merging Sand Spirit Slayer Magic with a fire-inclined Spirit Slayer Magic to produce glass, or merging water and earth to create mud. After the Spirit Slayer has obtained it, the Dual-Element Spirit Mode is capable of being invoked at any time that the wielder of Spirit Slayer magic deems to be suitable, with the caster inducing a replication of the activation sequences of the corresponding magics in order to activate these powers. Even though it's momentary, the user is able to call upon it when they are in a state of anger, their emotions influencing how long this boosted form is capable of staying active for. However, this ability places a heavy strain on an untrained body, to the point that even a single use is capable of completely draining the user of all their energy. If the user boosts up their power through the unlocking of their Second Origin, they are able to use this ability more easily with less strain. However, aside from a few cases, the Dual-Element Spirit Mode is extremely difficult to obtain.
