Vecna skull

The Vecna skull is an unequippable item that can be obtained from the Nomad shop at the Soul Wars minigame for 40 zeal. This item is also a rare loot from the Corporeal Beast. This shop can be found on the minigames teleport spell's second page under "Soul Wars". It can be activated an infinite number of times to gain a temporary +6 boost to your Magic level. This boost will not work while your magic level is already boosted by any other effect. It can only be activated every seven minutes per player, regardless of how many Vecna skulls are owned, with the exception of the Duel Arena - where, when you win or lose, the timer resets. A notice will appear once seven minutes has passed.

When you click on the "Draw power" from the Vecna skull, a text appears in your game box saying "The skull feeds off the life around you, boosting your magical ability."
