Improved Unarmed Strike (PH) , Stunning Fist (PH) , WIS 15,

You must declare that you are using this feat before you make your attack roll (thus, a failed attack roll ruins the attempt). By expending one Stunning Fist use for the day, you can project your ki to strike an opponent that is 5 feet beyond your normal unarmed reach. If the blow hits, it deals normal unarmed damage. This feat can be used only once per round.

Monks can use special monk weapons when using this feat, dealing damage according to the weapon.
