Stunning Fist

Prerequisites Dex 13, Wis 13, Improved Unarmed Strike, base attack bonus +8.

Benefits

You must declare that you are using this feat before you make your attack roll (thus, a failed attack roll ruins the attempt). Stunning Fist forces a foe damaged by your unarmed attack to make a Fortitude saving throw (DC 10 + 1/2 your character level + your Wis modifier), in addition to dealing damage normally. A defender who fails this saving throw is stunned for 1 round (until just before your next turn). A stunned character drops everything held, can't take actions,

Special

A monk receives Stunning Fist as a bonus feat at 1st level, even if he does not meet the prerequisites. A monk may attempt a stunning attack a number of times per day equal to his monk level, plus one more time per day for every four levels he has in classes other than monk.
