This shield, including the Vengeful and Merciless versions, have the ability to use the Defence ability, Provoke, while having the shield equipped and right-clicking and casting provoke. However, this does not queue the ability if another ability is being used while trying to cast it. The shield will degrade to a broken state after 60,000 charges of combat (but loses 2 charges per hit, so has a minimum duration of 5 hours of combat). It can be fixed by Repair NPCs such as Bob in Lumbridge, or at an armour stand in a Player-owned house. A full repair, without discounts, costs .
