You can make exceptionally powerful attacks.

Prerequisites: BAB +1, Strength 13

Benefit: On your action, before making attack rolls for a round, you may choose to subtract a number from all attack rolls and add the same number as heavy damage to all damage rolls. This number may not exceed your base attack bonus. The penalty on attacks and bonus on damage apply until your next turn.

Special: The bonus and malus only applies to melee attacks or throwing weapon attacks.
