Gadderanks invented this hammer to combat shades, which he feared and despised. During In Aid of the Myreque, players must fight and kill Gadderanks, and he will drop his hammer, which can then be used as a weapon. It deals more damage and is more accurate against shades, which makes it useful for the Shades of Mort'ton minigame. If lost, the Gadderhammer can be bought by talking to Aurel in the Burgh de Rott general store for 3,000 coins.
