The slayer helmet (e) was a single item worn in the headslot that combined multiple pieces of protective and beneficial slayer gear. It could be assembled after a player spent 400 Slayer reward points to learn how to craft one, additionally requiring level 55 Crafting. The Slayer level requirement for the slayer helmet was 35, which was also needed to complete the pre-requisite quest Smoking Kills. When worn, the helmet provided the special effects of all of the Slayer equipment which it was made from. Masked earmuffs did not work when crafting the Slayer Helm, it had to be be disassembled first.
One way to decrease the time it takes to getting 400 points is by doing 9 low-level tasks, and on the 10th completing a harder slayer master's task.
After unlocking the ability to make the helmet, a message appears in the chat window stating: The secret is yours. You can now combine a black mask, face mask, spiny helm, nosepeg and earmuffs into one useful item.
The items used to make the slayer helmet are:
An uncharged Black Mask, which gives a 12.5% Melee damage boost and 12.5% Melee accuracy bonus against the player's current slayer assignment.
A pair of earmuffs, which deafens the screams of banshees
A face mask, which allows the player to breathe in smoky dungeons
A nose peg, which blocks the aberrant spectres' stench
A spiny helmet, which protects the player from wall beasts when traversing the Lumbridge Swamp Caves
All of the aforementioned items are required to craft the helmet, as well as a Crafting level of 55 (can not be assisted). The helmet retains the abilities of all the items used to make it. It still gives the effect that the black mask does, but with better defence and bonuses, making it one of the best helms for slayer assignments.
For a player to construct the helmet, they must use one item on another if all the necessary items are in the player's inventory. The quest Smoking Kills is required to make the slayer helmet, and therefore must be completed before the Slayer helmet can be crafted, and worn. After being made, the slayer helmet may be disassembled and reassembled at any time (unless it has been enchanted to hold summoning scrolls).
The assist system cannot be used to make the slayer helmet although boosts may be used.
The slayer helmet costs 1,945,615 coins assuming all the components are bought from the Grand Exchange.
As of 27 January2009, it could be enchanted to hold summoning scrolls by Pikkupstix (with a summoning level of 20). When it was charged with at least one Scroll it took on a lighter colour. If the slayer helmet was charged to hold summoning scrolls, it also required level 20 Summoning in order to be worn.
It should be noted that enchanted helms of any kind could only be charged if the player had no other charged helms in their possession. Attempting to add scrolls to an enchanted Slayer Helmet while in possession of an already charged helm of any kind would result in the message, "You already have some charged headgear". Should this have happened, the player simply had to remove the scrolls from the helm that was already charged. The player would then be able to successfully add scrolls to their enchanted Slayer Helmet.
