Mage hat (class 1) is a piece of magic armour made in the Stealing CreationMinigame. It requires 1 crafting to be made, and 1 magic to wear (Hence not having any actual requirements). It requires one piece of class 1 clay to be created at a creation kiln.
Just like all other stealing creation items, this item can only be created and used within the minigame. It will disappear when a player leaves the game.
