Adamant spinyhelm

The Adamant spiny helmet 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, an Adamant Spiny helm provides 20% to Attack, Strength and Defence bonus only if they are fighting wall beasts. It requires level 45 Defence and level 50 slayer to equip. It can be bought from any Slayer Master for 150000 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.
