A Rocky Helmet is a held item that causes a Pokémon that makes contact with the holder to take ⅙ of its maximum HP in damage. It can be obtained as a tier 3 special drop. It is a possible drop from uncommon and rare boss Pokémon, or from certain wild Pokémon.
Before Reforged, this item had the following recipe. It was removed due to many held items being far too easy to make.
