A Slayer helmet is a piece of headgear made by combining a nose peg, facemask, earmuffs, spiny helmet, enchanted gem, and a black mask together. The helmet has the same defensive bonuses as a rune full helm. The helmet can be created by players with level 55 Crafting (boosts work) and who have unlocked the "Professional Slayer" ability for 350 Slayer reward points. Additionally, while worn, the helmet provides the special effects of all of the Slayer equipment from which it was made.
When worn on a Slayer assignment, the helmet provides the Melee boost of 16.67% against monsters assigned as the player's Slayer task. The helmet can upgraded with a Hexcrest and Focus sight to create a Full slayer helmet provide a 15% boost to Ranged and Magic as well.
Players can own more than one Slayer helmet at a time.
