This article is about the boss. For the Slayer monster, see Smoke devil.
Not to be confused with Nuclear smoke devil.
The Thermonuclear smoke devil, often referred to as Thermy, is the boss version of the Smoke devil, found in the Smoke Devil Dungeon. These require a minimum of 93 Slayer to kill. Located at the Smoke Devil Dungeon south of Castle Wars, the thermonuclear smoke devil can only be attacked on a smoke devil task.
This monster is the only monster to drop the Smoke battlestaff and the pet smoke devil. Their non-boss variants, however, also drop the Occult necklace.
A dwarf multicannon cannot be used inside the boss room. If attempted, the cannon will be destroyed (similar to areas like at KBD or KQ).
