Demon

Demons are a race of monstrous, immortal, supernatural, ancient and malevolent beings. Most commonly user retains their general form but with some additions; horns, claws, fangs, and tail are common, as are wings, more fit body and color change but there are several kinds of demons who are far less humanoid, varying from strange, surreal or even absolutely horrific. Their behavior is described as being wild and uncontrollable, with a sense of free spirit and enjoyment of all things fun. Most of the time, the pranks were harmless fun, but some could be upsetting and harmful, such as switching babies or leading travelers astray in places with which they were not familiar. They are often willing to bind themselves to magic-users as familiars, serving as spies and informants using their ability to take animal forms. They have some abilities relating to fire and are hard to kill, possibly to the point of being immortal.

Abilities

 * Curse Inducement: Demons can place a curse on whatever they wish. The exact effects can be nearly anything the user desires, ranging from minor annoyances to tortuously extended death. Among the most common effects are bad luck, various sicknesses, infertility, or physical defects when affecting people, breaking or working wrong or causing problems when used on objects and tendency to draw various disasters for places. Traditional magical curses include transforming the victim fully or partially into an animal/monster that fits the offense, blood-lust, insanity, unstoppable rages, unhealing wounds, misshapen/inhuman offspring, and a whole host of other effects.
 * Contract Bestowal: Demons have the ability to give a person a power or change an event through an agreement. With this in mind users of contract bestowal often are quite manipulative with their choice of words, as due to the nature of the power extreme caution is often used in order to not slip up and leave a gap in ones own words to accidentally give the user of contract bestowal a chance to warp the what the receiving party has asked for. For example if one was to agree to a contract entailing extreme strength or power the user of the power could transform the recipient into an uncontrollable beast or a destructive force of nature.
 * Corruption Inducement: Demons can use the ability to corrupt a person into doing anything. It does not control the victim, but it prevents them from realizing what they would, otherwise, not do as the user suggests. Therefore, they become much more malleable. The user needs a small amount of proximity and contact to corrupt someone. This proximity or contact is needed occasionally to prolong the effect.
 * Enslavement Branding: Most demons can manipulate the mind of target by branding the body with a symbol, effectively making the victim a slave to the user's will, binding them into mindless servitude.
 * Hellfire: Demons can generate and manipulate the cursed flames of Hell, which can completely destroy anything. The color of the flames varies, but may be black, blue, white, or the normal shades of fire, although probably in some way noticeably unusual. Sometimes, the flames are not generated, but instead summoned from the depths of Hell itself.
 * Regeneration: Demons have a strong regenerative ability more than any living being or human, able to heal any sort of injury caused by a conventional mean in mere seconds. That includes regrowing limbs and organs.
 * Illusion Manipulation: Most demons can create, shape and manipulate illusions/hallucinations, causing targets to see, hear, touch, smell and/or taste things which do not actually exist or cause them to perceive things differently from what they truly are. Some users can create complex and detailed worlds, while others may be able to only alter the way they or the target are perceived. As such, illusions can exist either solely in the physical or mental perceptions of the target or as external projections in the material world, like holograms and mirages. Additionally, these illusions can even be made powerful enough to become real enough to become tangible and physically interact with the target and their environment.
 * Inhuman Physical Capabilities: Demons possess inhuman strength, speed and endurance.
 * Shapeshifting (Flesh Manipulation): All demons, no matter how strong, possess the ability to shapeshift through the manipulation of their flesh. This ability can either be automatic or be influenced by the demon itself. The shapeshifting capabilities of low-level demons include: growing horns, possessing multiple hands or having sharp fangs.
 * Size Manipulation: Demons can manipulate their size, from tiny to absolutely gigantic while retaining their physical proportions, some may be able to alter targets density. Usually, strength and durability are proportional to the size assumed, but the target may gain increased abilities when growing or keep their normal ones when shrinking.
