The Slayer helmet, as its name implies, is a powerful helmet whilst training Slayer. The helmet is player-made during the quest Smoking Kills, by combining Earmuffs, a face mask, a nose peg, a spiny helmet, and an uncharged black mask. Once constructed, this slayer helmet will provide the bonuses of all of the counterparts that make up the helm.
A hexcrest and a focus sight can be added to the slayer helmet to make a Full slayer helmet which provides all the bonuses of the slayer helmet as well as ranged and magic bonuses. The colour of the "Slayer helmet" can also be changed to either red, yellow, green or blue by Xuan for 4000 loyalty points.
