Mindcrawler
The vampire employing this ritual creates a magical force in a victim's head which causes the victim to slowly lose his mind. The effects are dreadful and extremely effective. The Thaumaturgist simply places her hand on the victim's head for this ritual to take effect. The victim will feel only a minor burning sensation.
Over a period of one week, the victim begins losing his Mental Attributes. The first day the victim loses one point of Perception, the second day one point of Intelligence, the third day one point of Wits. The cycle repeats on the fourth day, with the victim losing another point of Perception, and so on for each day, following the same sequence until the victim's Mental Attributes are all reduced to one. The Mindcrawler then ceases.
The victim may rebuild his Mental Attributes at a rate of one point per week, applied to whatever Mental Attribute the victim decides to work on rebuilding. The material component for this ritual is a small tick dyed red and painted with a mystical symbol. The tick is then crushed and applied to the head of the victim.
