The Rune 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 spinyhelm, a Rune spinyhelm provides +25% to Attack, Strength and Defence bonus only if they are fighting wall beasts. It requires level 57 Defence and level 60 Slayer to equip. It can be bought from any Slayer Master for 300,000 coins. Unlike a normal spinyhelm this can't be used to construct a Slayer helmet. It also requires the completion of the Tears of Guthix.
