Prereq: BAB +6

Whenever you make a standard action attack or a charge, you now deal an additional amount of damage equal to the weapon dice plus strength. (or DEX if Agile Fighter or other ability) If you are using a weapon in two hands, you instead deal STR and a half.

If you are using an unwieldy weapon you instead deal double the damage of a normal attack (Ex. 3d6+10 → 6d6+20)
