Improved Knockout Punch

The character is extremely skilled at cold-cocking unprepared opponents.
Prerequisites: Brawl, Knockout Punch, base attack bonus +6.
Benefit: When making the character’s first unarmed attack against a flat-footed opponent, treat a successful attack as a critical hit. This critical hit deals triple damage. The damage is nonlethal damage.
Special: Even if the character has the ability to treat unarmed damage as lethal damage, the damage from a knockout punch is always nonlethal.
