Delicate

A character with the Delicate flaw suffers 1 point of stun damage whenever he makes a successful Unarmed Attack against an opponent. If the character suffers enough stun damage to leave him with less than half of his stun points, he can’t attempt an Unarmed Attack—he must regain a number of stun points sufficient to bring him back to the halfway mark (at least) before he can use the skill again.
