You and your allies work together to shake off mental effects.

Prerequisites: Drow or Hobgoblin

Benefit: You can deal damage to an ally in order to help them break an ongoing mind-affecting effect that allows a saving throw. You must cause at least 5 points of damage to your ally with an attack, spell, or other ability. The ally then rerolls their saving throw against the mind-affecting effect, with a +1 bonus for every 5 additional points of damage your attack caused. If their save is successful, the mind-affecting effect ends. Only damage actually dealt counts for purposes of this feat; nonlethal damage and damage reduced or eliminated by damage reduction, resistances, and so on does not qualify.
