Your attacks are truly devastating.
Prerequisite(s): Power Attack.
Benefit: When you use Power Attack, you gain a +3 bonus on melee damage rolls instead of +2. When your base attack bonus reaches +4 and every 4 points thereafter, the amount of bonus damage increases by +3 instead of +2.
In addition, the bonus damage from this feat is doubled on a critical hit, before it’s multiplied by the weapon’s critical multiplier.
