Style Strike

At 5th level, a monk can learn one type of style strike. Whenever he makes a flurry of blows, he can designate one of his unarmed strikes as a style strike. This attack is resolved as normal, but it has an additional effect depending on the type of strike chosen. At 9th level, and every 4 levels thereafter, a monk learns an additional style strike. He must choose which style strike to apply before the attack roll is made. At 15th level, he can designate up to two of his unarmed strikes each round as a style strike, and each one can be a different type.
