The Thermonuclear smoke devil is a Slayer boss in the Smoke Devil Dungeon. It requires 93 Slayer to attack and drops the occult necklace and smoke battlestaff.
Getting there
Equip a facemask or Slayer helmet before entering the dungeon. Keep it equipped throughout the trip.
Choose Therm. smoke devil in Sarim Hub, then enter the nearby dungeon. Head northwest to the boss crevice and choose Use. Confirm the warning to enter the public room.
Bring a melee setup, food and any combat supplies you need. Its ranged and Magic defences are high, so melee is a straightforward choice.
Fight
- Check that your facemask or Slayer helmet is equipped.
- Attack the boss and keep your hitpoints high. It attacks quickly.
- Collect your loot and continue only while you have enough supplies.
With smoke protection, its normal attacks hit up to 8 every two ticks. Protection prayers do not block these attacks. Use offensive prayers if you want the damage boost, and bring food rather than relying on a protection prayer.
Without smoke protection, the dungeon damages you and the boss uses a stronger smoke attack. If you lose or remove your helmet, leave and replace it before continuing.
Use the crevice to leave the boss room when you need to resupply.
Drops
The boss always drops ashes. The following rates are per kill in the normal world, without reward bonuses or extra rolls.

Pet
