Black mask

There is an imbued version of this item here.

The Black mask is a helmet worn in the head slot. The mask has the same stats as a black med helm. It gives a player 15% Attack and Strength boosts against all monsters on the player's current Slayer task. You need 20 Strength, 10 Defence and 40 Combat to wear it.

The black mask is a rare drop from Cave Horrors, which many people camp as black masks are high in demand. However, killing them requires 58 Slayer and the completion of Cabin Fever, which deters many players from killing them.

When dropped by Cave Horrors, the mask has 10 charges that will be discharged to monsters at random. These charges reduces the opponent's Defence by 3-10 levels. Once the mask has been drained of all 10 charges, there is no way to recharge it; however, the Attack and Strength boosts still remain.

For 1,250,000 Nightmare Zone points, you can upgrade your black mask to a Black mask (i). A Black mask with charges (1-10) may also be imbued.

Players can craft a black mask and other Slayer items into a Slayer helmet, provided they had acquired the ability to make the helmets. Slayer helmets are valued because of their effects and the fact that they are not tradeable.
