About Black mask

The black mask is an inert-seeming cave horror mask, an uncharged version of the powerful black mask. It is obtained from cave horrors on Mos Le'Harmless and must be charged before it provides its powerful Slayer bonuses. When charged, the black mask boosts the wearer's damage and accuracy against the player's current Slayer task by a significant amount, making it one of the best Slayer helmets in the game. Because the charged mask is so important for Slayer, the inert version has lower value until charged. The inert black mask is an uncharged cave horror mask and a valuable Slayer item once charged.
