Pox

This spell attempts to afflict the target with a powerful, wasting disease that devours them from the inside. Each half-hour the target will take damage, and there is a chance the disease will spread to other people near to them. As the disease spreads, the duration will be lessened on each new victim. This disease will deal a penalty to the victim's strength, and one so afflicted has a chance to have commands he inputs be cancelled, his body refusing to respond due to the pain of the disease. This spell cannot afflict the undead.
