STUNNING FIST [Combat, Martial]
You know how to strike opponents in vulnerable areas.
Prerequisites: Improved Unarmed Strike, Dex 13+, Wis 13+, BAB +8
Benefit: Declare that you are using the feat before you make your attack roll (thus, a missed attack roll ruins the attempt). It forces a foe damaged by your unarmed attack to make a Fortitude saving throw (DC 10 + one-half your level + your Wis modifier), in addition to dealing damage normally. If the defender fails his saving throw, he is stunned for 1 round (until just before your next action). A stunned character can’t act and loses any Dexterity bonus to Armor Class. Attackers get a +2 bonus on attack rolls against a stunned opponent. You may attempt a stunning attack once per day for every four levels you have attained, and no more than once per round.
