Prerequisites
Constitution 15,
Clarity Of Pain,
Improved Iron Will,
Iron Will.
Benefit
When you fail a saving throw to resist possession or a dominate spell, you can deal 4 points of
Constitution damage to yourself and reroll your saving throw as an
Immediate Action. You cannot reduce or negate this damage in any way, and the only way to
Heal the damage is through natural recovery; magical methods don't work. You must take the result of the second roll, even if it is worse. If you succeed at the second saving throw, you also become immune to that spell or ability from that creature for 24 hours. You must be wielding a lethal piercing or slashing weapon, or possess a claw natural attack or some way to draw such a weapon reactively without using your
Immediate Action, to use this ability.
