Medusa’s Wrath
You can take advantage of your opponent’s confusion, delivering multiple blows.
Prerequisite: Improved Unarmed Strike, Gorgon’s Fist, Scorpion Style, base attack bonus +11.
Benefit: Whenever you use the full-attack action and make at least one unarmed strike, you can make two additional unarmed strikes at your highest base attack bonus. These bonus attacks must be made against a dazed, flat-footed, paralyzed, staggered, stunned, or unconscious foe.
