Dark Regulus

 (暗いレグルス, Kurai Regurusu) is a type of Caster Magic and subspecies magic ability of Darkness Magic and Fire Magic, as well as a much darker variation of the original it originates from, with the exception being that it replaces the natural Light Magic it emits with the use of darkness, effectively producing dark flames with the ability to consume other forms of Fire Magic.

Description
Although a somewhat unique variation of said Fire Magic, it has the unique advantage of adopting the qualities of both elements in order to produce devastating attacks, enabling the user to imbue parts of their own body with the Magic itself for melee combat, however in this case the Magic manifests itself as dark flames that encompass whatever region of their person they desire, quickly igniting into a dark burst of fire. Either up close or from a distance, Dark Regulus has a tremendous ability for ranged combat that renders it a viable weapon for long-distance battles as well as close-quarter combat, commonly doing so by firing or unleashing dark flames from the surface of their palms or outreaches of the user's body in order to close the distance between themselves and those that are located at a sizable distance from her. Moreover, what truly makes Dark Regulus a rather unique fusion between fire and darkness is the special way in which it incorporates the properties of both elements when producing dark flames, effectively giving birth to an intense, burning flame with the power to snuff out light thanks to the dark properties it has as an element of darkness. An advantage of using both of these elements in tandem with one another is their capacity to absorb "light" from a variety of sources in different forms, such as the light emitted by other types of fire magic, the brilliance produced by light-based abilities, either artificially or magically, all in order to nullify a foe's attacks while using the absorbed Magic for themselves, enabling the caster to intensify their flames at a much higher degree than they could achieve on their own.

This is commonly achieved due to the special properties the dark flames have — with the fire aspect, in which it can spread around a targeted source in order to continue burning, and darkness, the lack of visible light or power to reduce it light, they generate a flame capable of consuming light, effectively adding fuel to the flame the more light is added to the equation. Additionally, whilst Dark Regulus appears to be unlimited in the amount of flames the user can absorb, there actually is a limit to the amount of light and fire one can take in with their dark flames, eventually reaching their limit the moment the caster takes in too much. The exact amount of light-based energy they can take from their surroundings is commonly based on the level of skill one has with it and the general amount of magic one can hold inside their body, allowing wizards known for having a high capacity for magic storage being able to contain or withhold greater amounts of light inside their own bodies in comparison to ordinary mages. Whenever they do reach their maximum capacity, the wizard in question can expend the accumulated energy taken in from their flame and expel it outward in the form of additional flames, or simply extinguishing it in order to increase the volume in which the fire can they can produce grows. However the more light that there is to absorb, the longer the flame lasts and the stronger it becomes, being a direct result of the dark element aspect of the flame siphoning and absorbing the original source of the light, effectively nullifying it after direct contact.

In terms of practical use, as a style of magic with the dualistic nature of fire and darkness, Dark Regulus is naturally compatible with spells belonging to both elements in their respective styles, such as Molding Magic in order to alter the form or shape of the flame, making it rather versatile to the numerous different types of Fire Magic spells of techniques that exist, be it physical in nature of a simple ranged attack. When summoned, the texture or overall heat produced by these dark flames are many times greater than most traditional forms of fire created through magic, while at the same time having an extraordinary increase in power power thanks to incorporating the destructive Dark Magic, making it much easier for the user to use it's physical form for destroying objects or obstacles in their path. It should be noted however that since it is classified as a type of Fire Magic, it can unfortunately be consumed through the use of fire-based Slayer Magic, quite easily making it susceptible toward nourishing the opposing wizard. On the other hand, these very flames are capable of absorbing the flames produced by these types of wizards, adding the slayer's magic flame unto their own for greater strength, making it somewhat of a power struggle-esque dilemma between due to both the user and the slayer being able to consume each other's fire for a quick charge. It should be taken into account that the notable difference between Dark Regulus and all other forms of fire-related magic is the fact that the process of producing these dark flames is much less taxing on the caster, with the traditional limitations of producing fire being elevated much further by a large margin in comparison to its various counterparts.

In normal instances, the act of producing a flame requires a combination of stamina and magic energy, making it a finite resource they can call upon, especially during an extended period of time in battle. As long as the user himself has a steady stream of fire or light for them to draw fuel from, they have lesser dependency in maintaining or producing their own flames, commonly using the magic energy belonging to others rather than use their own during the entire process.
