A dust devil is a monster found in the Smoke Dungeon and the Catacombs of Kourend.
Dust devils will be not assigned as a slayer task until Desert Treasure has been started. They require a slayer level of 65 to kill.
A facemask or slayer helmet should be worn when fighting a dust devil. They use clouds of dust to blind and choke their victims.
Catacombs of Kourend – Level 110 Dust Devils can be found here. They have 130 hitpoints and a higher damage potential.
