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, with the exception of one kill for the Western Provinces Diary (provided that the player has 93 Slayer without boosting).

It is the only monster to drop the Smoke battlestaff and the pet smoke devil. Their non-boss variants also has a chance to drop the occult necklace, but at a lower drop chance.

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).

Trivia

• The thermonuclear smoke devil was graphically updated on 27 September 2018 as part of a update. Prior to the update, it was simply a larger version of the smoke devils scattered across the dungeon.
• The thermonuclear smoke devil, along with the Kraken, are the only slayer bosses that can be fought with another player.
