In combat the current attacker can announce they are going to target a worn or carried item of a foe. By doing so the item is harder to hit. The items AC becomes the targeted avatars AC plus their tier level plus the roll of their tier die. If the item in question also has its own AC this is also added. If the item is hit It is deactivated (unattuned). If the hit item is a held item, it cannot be used again until it has been through a ritual attunement of at least 10 minutes.
