Tainted Prestige Classes Edit
The two prestige classes presented here use taint as a source of power. Depending on your campaign, certain taint scores (or lack thereof) could be prerequisites for other published prestige classes, such as the alienist or the blood magus.
Behind The Curtain: Taint Edit
Taint can be added to campaigns fairly seamlessly. It's generally best to limit the number of places and items that can impart taint, to reduce the bookkeeping load on players and the DM.
Taint makes evil a physical threat to the well-being of the characters. It can have a lasting impact on characters, even killing those who remain exposed too long.
