The character must declare that she is using this attack on her first turn of the round, and she can take no other attack actions, though she can use move actions. The character takes a -5 penalty on her attack roll but if she hits she multiplies her unarmed damage dice (excluding damage modifiers) by her number of attack actions per round. Example: A character with four attack actions per round takes a -5 penalty to her attack roll but deals 4d6 damage, plus any bonuses from feats or Strength.
Prerequisite: Combat Martial Arts
Special: Flurry of Blows can only be used with unarmed strikes.
