Mithril spinyhelm

The Mithril spinyhelm is a helmet designed to protect the player from the attacks of a Wall Beast located in the Lumbridge Swamp Caves. Unlike a normal spiny helm, a Mithril spiny helm provides +17% to Attack, Strength and Defence bonus only if they are fighting wall beasts. It requires level 39 Defence and level 40 slayer to equip. It can be bought from any Slayer Master for 80000 coins. Unlike a normal spiny helm this can't be used to construct a Slayer helmet. It also requires the completion of the Tears of Guthix.
