Demonic Illusion: Dark Charade

This causes the victim, or victims, to hallucinate dark shapes moving in the corner of their sight, which will promptly disappear when focused on. By doing so the practitioner is able to break an opponent's concentration at the task at hand, weakening them at the same time. Furthermore, if this technique is used to a greater degree, and under the right conditions, it can even inspire fear as the target begins to witnesses multiple shadows lucking in their peripheral vision, that never appear to be there.
