Darkwave is a spell that creates a stream of black waves that cause significant damage to the target. Though primarily used by the Blood Spiral, a number of the Organization's Suits have been taught the spell. According to the Suit Handbook, Darkwave is dangerous to use while chasing a target as one's feet would not be firmly planted.
