Description: By performing a precise strike just below an opponent's ear, you can inflict temporary deafness

Prerequisites: Base Attack Bonus +2, Improved Unarmed Strike, Void Use

You may perform a special unarmed attack against an opponent forcing him to make a Fortitude save (DC 15 + your Dexterity modifier + 1/2 your inkyo level, if applicable)/ If this save fails, the target is deafened for 24 hours. If the target possesses the Cleansing Spirit feat they may heal the damage to their hearing as a standard action.
