Motion Spirit

Motion Spirit (動迫, Dōhaku; Idiomatically meaning "Exciting the Soul") is an advanced Seith Magic spell.

Description
Motion Spirit is an advanced Seith Magic spell that involves a considerable amount of magical power to procure properly. Users of this spell actually place a portion of their own soul into an inanimate object. The exact process of this isn't described, but it likely involves utilizing their magical power as a bridge between one's soul and the physical realm, intertwining the two in a single plane of existence momentarily in order to - quite literally - animate the said object. The animation of the object generally involves the caster manipulating their shape, length and the like and allowing it to move on their behest. This allows potentially useless items, such as a mask, to be forged into a full-blown suit of armor, giving the user an extreme advantage. However, the constant surge of magic makes it difficult to use for an extended period of time.
