Armor (shield), common
You gain the benefit of a shield while you hold it. It weighs 2 pounds instead of 6, and it is strapped rather than gripped, so the hand behind it can hold a line, a lamp, or a rail — but not a weapon.
It floats and cannot be submerged. A creature holding it cannot sink below the surface of water and can keep a further 200 pounds afloat with it, sea gear counted in.
