Thermonuclear Smoke Devil Best in Slot Gear & Strategy Guide

The Best in Slot setup for Thermonuclear Smoke Devil depends on your combat style and budget. The gear grid above shows the top-ranked items for each equipment slot — sorted by the stats that matter most for this fight (accuracy vs. max hit vs. defence). For most players, near-BiS gear (one tier below the absolute top) clears thermonuclear smoke devil comfortably without needing a max-stake bank.

Look at the inventory recommendation below the gear list for prayer potions, food, and any boss-specific items you should bring.

Check the "Requirements" line at the top of this guide — it lists the recommended combat stats and quest prerequisites. As a general rule, you can engage thermonuclear smoke devil at the listed minimums, but expect slower kills and more food consumption. Higher combat stats (especially Strength, Ranged Strength, or Magic Damage % depending on the style) translate directly to faster, safer kills.

If your stats are below the recommended minimums, consider training at easier slayer tasks first — efficiency goes up dramatically once you can actually use BiS gear effectively.

No. Full BiS makes kills faster but is rarely required. Most players clear thermonuclear smoke devil with mid-to-high tier gear — the difference between a Bandos chest and Torva, or a Trident and Shadow, is typically 5-15% DPS. That matters at endgame raid speeds; it doesn't matter for slayer or casual PvM.

Use the BiS gear above as your aspirational target, but start with what you have. The boss tells you what works through your kill speed and food usage.

Travel to Thermonuclear Smoke Devil varies by boss. Check the OSRS Wiki for the exact teleport or walking path — most bosses have a fairy ring code, a slayer master teleport, or a quest reward teleport that works. Bring a way back to the bank between trips: skull-tricks, Achievement Diary teleports, or a House teleport are common.

If you're fighting Thermonuclear Smoke Devil on a slayer task, your slayer master's teleport will usually drop you right at the lair entrance.

The "Notable Drops" section above lists the top items from Thermonuclear Smoke Devil — the ones most players are actually grinding for. Most boss tables include a unique (the most valuable rare drop), a handful of mid-tier uniques, and a steady stream of GP-value drops like alchables, runes, and crafting materials.

Drop rates and exact loot tables come from the OSRS game data; specific roll mechanics (1/X, scales with kill count, etc.) vary boss-to-boss — check the OSRS Wiki for full drop tables and rate-of-return calculations.

Most BiS items for thermonuclear smoke devil come from raids (Tombs of Amascut, Theatre of Blood, Chambers of Xeric) or specific bosses you'd need to grind separately. The Grand Exchange shortcuts the grind for tradeable items: BiS gear costs anywhere from a few million to a few billion GP per piece.

For non-Ironman accounts almost everything is tradeable, so the fastest route is usually to farm GP at a profitable boss, then buy the tradeable upgrades off the GE rather than grinding each drop directly.
