Sunder Armor

Str 13, Power Attack

You can use a melee attack with a slashing or bludgeoning weapon to strike a piece of armor that your opponent is wearing. Doing so does not provoke an attack of opportunity from your opponent. If you score a critical hit against your opponent while targeting his armor, roll damage normally and make a Strength check (DC 15 + the targeted armor's armor bonus). If your damage surpasses the armor's hardness and your Strength check succeeds, the armor you have targeted is reduced by 1 point of armor bonus until repaired. You cannot damage magic armor that has an enhancement bonus unless your own weapon has an enhancement bonus equal to or greater than the armor's.

Targeting an opponent's armor provokes an attack of opportunity.

A fighter may select Sunder Armor as one of his fighter bonus feats.

You can strike blows that damage and destroy armor.
