Prerequisites: level 5, Power Attack

Benefit: When you perform a single attack as a full-round action or refrain from taking a move action and perform a single attack as a standard action, you receive a +2 to DC of the corresponding attack. Your heavy multiplier increases by 1 when performing such attacks.

You may use improved two weapon fighting to make two attacks in that case the bonus decreases to 0.5.
