Dark Écriture (MC)

Dark Écriture (闇の Yami no Ekurityūru) is a Caster Magic and a type of Letter Magic and Eye Magic (MC) involving the usage of writing runes for various effects.

Description
It is a form of Letter Magic that allows the caster to write runes, sometimes without a writing tool such as a pen or a quill, for various types of effects. Essentially, the spells used for this Magic work only on what the caster writes with it; in other words, what they write goes as follows, making it a sort of "rule" in using Dark Écriture.

The properties of the Magic is centered on the writing of the runes; however, if rewritten correctly, the effects will change. The runes can be written on an object, person, or even in midair for the effects to take place.

The runes can be written for different purposes, such as traps, and offensively can be cast upon an opponent to inflict either physical  or mental injury. The caster can also conjure an element for usage of this Magic, like poison. Death is also a possible effect. However, simple usage of this Magic that is convenient for the user, such as teleportation or flight, can also be used. Another type of spell is actual transformation, in which the caster is able to transform themselves and be granted a different appearance, even strength.
