Taint

The Taint is a debuff that blocks all healing. While it lasts, health cannot be restored by any method, and heal spells, potions and scrolls do nothing for it. It can come from contact with a lime green, oily residue, and it runs on a five-minute timer. Its description compares it to having the giggles, except that the afflicted is balanced on the edge of death. On its own it is not a serious threat and simply has to be waited out.
