Demonic skull

The demonic skull can be purchased from the Mage of Zamorak in either south-west Varrock or the Wilderness for 550,000 coins. While wearing it, Runecrafting experience from the Abyss will increase from 2.5 times the normal amount to 3.5 times the normal amount. An icon is shown above players' heads when wearing the skull, and if you are killed with it in your possession, 500,000 coins will drop in its place.
