Panther Parry
Your vicious strikes impair your foe’s ability to attack you when you move.
Prerequisite: Wis 15, Combat Reflexes, Improved Unarmed Strike, Panther Claw, Panther Style.
Benefit: While using Panther Style, your retaliatory unarmed strikes are resolved before the triggering attacks. If your retaliatory unarmed strike deals damage to an opponent, that opponent takes a –2 penalty on attack and damage rolls with the triggering attack of opportunity.
