Gas mask

The Gas mask is a quest item made by Edmond's wife during the Plague City quest so that the player can enter West Ardougne without being affected by the "plague" there. They are also dropped by the mourner who drops the garb for Mourning's Ends Part I. It also protects the player from damage in the Smokey Well and Desert Slayer Dungeon in Desert Treasure and beyond, however they don't protect from Dust Devils' attacks.
