The Smoke Devil Dungeon is a dungeon located south of Castle Wars, housing smoke devils that can only be killed while on a slayer task.

Players may enter without a slayer assignment, but upon attacking any monster inside the dungeon, Breive will stop them from doing so, claiming that they are not assigned to kill them.

Attempting to enter the dungeon without a face mask (or slayer helm) will result in Breive warning the player that they should get some protection first before entering. Without one, the player will take periodic damage from the smoke (shown as "cough"; "wheeze" if the smoke damages you to 1 hitpoint). The smoke cannot kill the player, but a face mask or slayer helm is still needed to fight the smoke devils.

The smoke overlay effect within the cave can be toggled on and off by right-clicking the cave's entrance and selecting the Smoke option.
