About Thermonuclear Smoke Devil

The Thermonuclear Smoke Devil, affectionately known as 'Thermy,' is the level 93 Slayer boss found in the smoke-filled depths of the Smoke Devil Dungeon. While the boss itself isn't mechanically complex compared to raids, it has high defensive stats and can deal significant damage if not handled correctly.

The main reason players farm Thermy is for the Smoke Battlestaff, a key item for certain Magic training methods, and the prestigious Pet Smoke Devil. It is also one of the best sources of Occult Necklaces for Ironman accounts. Because of the high Slayer requirement, it represents a significant milestone in account progression.

Expos.GG provides an elite farming service for Thermy. Our boosters utilize the most efficient methods, including the latest Magic and Melee metas, to ensure your task is completed as quickly as possible. We maximize your kills per hour, giving you the best chance at that pet or a valuable unique drop without the repetitive clicking.
