• Prerequisites: Improved Sunder, Power Attack, base attack bonus +6, Strength 13.
• Benefit: You receive a +2 bonus on checks made to sunder an item. This bonus stacks with the bonus granted by Improved Sunder. Whenever you sunder to destroy a weapon, shield, or suit of armor, any excess damage is applied to the item’s wielder. No damage is transferred if you decide to leave the item with 1 hit point.
