Magic Weapon Abilities - Shattermantle
A shattermantle weapon damages an opponent's spell resistance. Each time the weapon strikes a foe with spell resistance, the value of that spell resistance is reduced by 2 for 1 round. The penalties for multiple hits during the same round stack. For example, if the wielder succeeds on three attacks in the same round against the same foe with spell resistance, that foe's spell resistance is reduced by 6 until the beginning of the wielder's next turn. This weapon property does not grant the bearer the ability to determine how much spell resistance (if any) a target might have.
