Cleansing of the Flesh
Vampires must drink the blood of mortals in order to survive and, accompanying this bane is the risk of becoming addicted to mortal vices: illegal narcotics and alcohol. In some cases, Kindred lead their unlives as hosts to a number of sexually transmitted diseases, such as AIDS. The Warlock casting this ritual must spend one full night in a bathtub filled with purified water. Throughout the night, the thaumaturge must expunge all but the smallest drop of his blood from his body, a little at a time over the course of one night. As the blood is released from the body, all addictions and diseases the vampire formerly housed will no longer burden him.
System: The caster lies in a vessel of purified water and bleeds out all but one of his blood points, roughly two points an hour. All addictions to drugs and all diseases that are not supernatural in nature will no longer hinder the thaumaturge beginning at night's end, though he will likely be quite ravenous after performing the ritual. This ritual may be performed on another, who must open his own veins, with the Warlock chanting beside the tub.
