One of your attack forms that normally deals ability damage, ability drain, or energy drain can also deal corruption or depravity.
Prerequisite: Natural attack that deals ability damage (including poison), ability drain, or energy drain.
Benefit: Choose one of your natural attacks that deals ability damage or ability drain or bestows negative levels. That attack now increases the target's corruption or depravity score by 1 point along with the ability damage or drain it deals. If your attack deals ability damage or drain to a physical ability score (Strength, Dexterity, or Constitution), it now also increases the target's corruption score. If the attack deals ability damage or drain to a mental ability score (Intelligence, Wisdom, or Charisma), it now also increases the target's depravity score. If the attack bestows negative levels, you can choose whether it increases a specific target's corruption or depravity score.
If the attack you choose bestows more than one negative level, it now increases the target's taint score by 2 points. You can choose to have it increase a target's corruption by 2 points, increase a target's depravity by 2 points, or increase each score by 1 point.
