The Mask of Stone is a slayer mask obtainable from the Shattered Worlds reward shop for 2.5 million anima. It provides several bonuses for players looking to train their Slayer skill, listed below. When the double drops, damage, and xp boosts have expired (after killing 300 Cockatrices), the mask will become the Helm of Petrification which has similar benefits, but does not provide double drops, extra damage or an XP boost.

It has a requirement of level 20 Defence to be worn. It also counts as a mirror shield equipped, granting the use of two-handed or dual wield weapons.

Benefits

The teleport

Force Slayer task	When the mask or helm variant is worn: One task per day at: Mazchna/Achtryn. Attempting to force a task with the mask or helm at a Slayer Master that does not assign the creature, will instead be directed to a Slayer Master that can assign them. The mask or helm warns players if the creature is on their block list before accepting. The activation chance of the Slayer master cape perk if triggered, takes priority over the mask or helm, preserving their ability to force a slayer task. The mask or helm will not work if the Slayer Master is in the process of setting up a Co-op Slayer assignment. The cool down period of this ability may be checked via the "Check Kills" option on the item's right click menu.
Daily teleports	Two free daily teleports to: Inside Fremennik Slayer Dungeon next to the cockatrices.
Slayer task stat boost	Until helm is unlocked and mask is worn: grants the player 12.5% damage and accuracy if the player is on the Slayer assignment for the corresponding monster. It will override the damage and accuracy granted by the slayer helmet that is placed on the slayer helmet stand, even if the one on the helmet stand is better.
Additional Slayer XP	Until helm is unlocked and mask is worn: Grants additional Slayer XP equivalent to the Slayer level required to fight them. This is given regardless of the current assignment the player has and in addition to assignment and/or contract xp. The XP awarded by the mask can be boosted by items.
Enhanced drops	Until helm is unlocked and mask is worn: Grants double drops in accordance with the base amount received for every 10th kill, including charm drops. This does not double effigy or clue scroll drops.
Kill count	When mask or helm is worn: Tallies every creature killed. Each mask has a set amount of kills assigned to it that, once reached, the mask turns into its helm variant, ending the additional Slayer XP and double drops effects. The kill count continues to be tracked beyond this point, up to 1,048,575 on the item's tooltip. However, only up to 999,999 can be displayed to others with the "check kills" option.
Check kills	A right-click option outputs total kills of that creature. 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, the player is free to switch between it and the mask version - this change is a cosmetic effect – this does not restore the additional Slayer XP and double drop effects to the mask.
Slayer item	When the mask or helm variant is worn: Will act as a mirror shield.
Emote	After the helm version has been unlocked, a right-click option is added to the helm while equipped that activates an emote in which the player is transformed into the corresponding creature for a few seconds.

At any point, the kill count can be reset to 0 by using a Spirit of Battle on a mask or helm. This will restore the Slayer XP and drop modifier effects if the helm was previously unlocked, and disable the ability to emote or swap to the helm cosmetic until the required kill count to unlock them is reached again.
