The Mask of the Abyss is a reward from the Treasure Hunter minigame. It was previously available on the Squeal of Fortune minigame before its removal on 4th February 2014.

This mask provides several bonuses for players looking to train their Slayer skill against abyssal demons. After the player has killed 900 demons while wearing the mask, it will transform into the Helm of Warping which has similar benefits, but does not provide extra drops or damage, or the XP boost.

If the mask is lost, it can be retrieved from Diango or Ianto for a fee.

Benefits while worn
Guaranteed task Once per day (midnight GMT reset), while wearing the relevant mask, the player can guarantee their next assignment will be for abyssal demons. Players will still need to go to a slayer master that normally assigns these creatures (Sumona, Duradel/Lapalok, Kuradal) – if not, they will be told which slayer master does assign them. This does not work for players in the process of setting up a co-op slayer assignment.
Slayer damage boost The mask confers the same damage boost against abyssal demons (but only while on assignment) as the slayer helmet.
Slayer XP Killing a abyssal demon while wearing the mask grants an additional 85 Slayer XP - the number equivalent to the Slayer level required to fight it. This is given regardless of current assignment, and in addition to assignment and/or contract XP. The XP awarded by the mask can be boosted by items.
Extra drops Killing abyssal demons while wearing the mask will grant additional drops for every 10th kill. This grants a second roll on the creature's drop table including: the 100% drop, the main drop, and the charm drop (and any other tertiary drops.)
Kill count Every abyssal demon killed is tallied, while the mask is worn. The mask has 900 kills assigned to it that, once reached, ‘uses up’ the Slayer XP and double drops effects, and turns the mask into a helm. A Spirit of Battle can be used to reset the mask's kill count to 0, enabling these benefits once more. The kill count can be tracked up to 999,999.
Trophy drops The odds of receiving an abyssal head are doubled.
Slayer item The mask acts as a face mask.
Right-click benefits
Daily teleports The mask can, up to twice per day, teleport its owner directly to a choice of locations where abyssal demons can be found. Players will need access to Morytania, an assignment from Kuradal, discovered the Fairy Ring to the Abyss, and have level-85 Slayer to use these teleports.
Check kills The mask can put a message into chat that shows the owner's total number of abyssal demon kills. If the helm has yet to be unlocked, there’s also a message to say how many more kills are needed to do so.
Change look After the helm version has been unlocked, players are free to switch between the helm and mask versions, as a cosmetic preference only – this does not restore the Slayer XP and double drop effects to the mask, only a Spirit of Battle can do that.
