Tainted

Survive the Disease: Corruption to the Third Stage, and beat the DC.

Tainted individuals have managed to survive the corruption process and not only beaten out the sickness, but gained tremendous strength from it, as well as an inherited weakness. Your blood has turned black, and your tendency to lean toward negative emotions has increased, generally anger or depression. But it isn't unresistable by any means, for further roleplay details and lore see the Taint article. Can only be removed via a Wish spell. Must be taken as a feat.
