A good Kn: Religion check will tell you some things. Ashlyn, Tessa, and Marot can determine the following if so inclined:
- When first exposed, restorative magic (restoration, etc.) can lessen taint. This must be done soon to remove the taint, and can prevent spilling over into the next level of taint. However, if it settles in (a day), only a miracle or wish lessen this level.
- Other spells (atonement, remove curse, etc.) can reduce taint. It cannot remove taint below its currently level (its too ingrained).
- There are rituals of certain faith that can reduce taint. Mental depravity can be reduced with week long rituals, while time in a sacred spring can reduce corruption.
- There are certain sacred substances that can help protect from taint; but they only last for so long. Some might be found in the caravan... or perhaps in the ruined Barovian church.
