Strike a Weapon
Strike a Weapon
You can use a melee attack with a slashing or bludgeoning weapon to strike a weapon or shield that your opponent is holding.
The attacking weapon must be no more than one size category smaller than the weapon attacked. (Treat a buckler as Small, a small shield as Medium-size, a large shield as Large, and a tower shield as Huge.)
Doing so provokes an attack of opportunity from the opponent because you are diverting your attention from him to his armaments.
Then you and the defender make opposed attack rolls. If you win, you have landed a good blow against the defender’s weapon or shield. Roll damage and deal it to the weapon or shield (see Strike an Object, above).
Magic Weapons and Shields: The attacker cannot damage a magic weapon or shield that has an enhancement bonus unless his own weapon has at least as high an enhancement bonus as the weapon or shield struck. Each +1 of enhancement bonus also adds 1 to the weapon’s or shield’s hardness and hit points. If your shield has a +2 enhancement bonus, you add 2 to its hardness and to its hit points.
