Knightmare Magic

Knightmare Magic (ナイトメア魔法, Naitomea Mahō) is a Caster,HolderandLost Magicthat incorporates various uses of one's deepest and greatest fear, but is considered forbidden among mages, even though not many are aware of its existence. Due to its nature, it is often mistaken for a Magic of the Black Arts, though it has been confirmed to not be connected to them.

Description
Knightmare Magic has three methods for the user to manipulate their greatest fear for their own advantage, which with enough trainning, all three can be used, but not at the same time, as there is only a singular fear to be used, which is what the user fears the most.

However, simply using this magic requires the user to be able of overcoming and/or facing their fears to be capable of using it, otherwise it becomes completely useless. Once the magic is used, the user's fear become a sentient being existing within it, no matter what said fear may be, it will have a mind of its own, but isn't neccesarily evil, depending on what the fear is, otherwise, it's only purpose would be to frighten the user so that it would be unable to use the magic and manipulate it.

Armor
The basic manipulation of the user's fear, is to "wear" it as a "Fear Armor" (恐怖の鎧, Kyōfu no Yoroi), though despite its name, it isn't neccesarily a suit of armor, rather, it can take several forms, such as gloves, a mask or simply a shirt, though it entirely depends on the fear, as the Fear Armor represents the fear, and if the fear is something, such as a creature or person, then the Fear Armor may mimic its attire or form.

When the Fear Armor is worn, the user is capable of using abilities related to said fear, most commonly having the user's physical abilities enhanced, but may also gain a unique ability that represents the fear. The user may also reveal said fear to others, causing them to experience it as well, though it requires physical contact. A Fear Armor has a negative effect on ordinary humans, as its aura makes them see their own fears and experience them as if they were real, while in reality nothing is happening, while Mages are capable of resisting it with their magic energy.

Wearing the Fear Armor is a basic method for the fear to try and control the user, as it may not wish to be used, and would control the armor itself, thus also controlling the user's movement depending on what the armor's form is, though with enough trainning one can resist this.
