What you need before entering

Smoke devil or boss task. A diary kill has a task exception; 93 Slayer is still required.

This guide is an orientation for the stated method. Confirm current requirements and practise mechanics before risking valuable equipment.

Thermonuclear smoke devil weaknesses and hazards

Wear a slayer helmet or other valid smoke protection.

Recommended fight plan

  1. Wear a slayer helmet or other valid smoke protection.
  2. Protection prayers do not block the boss’s typeless attack. Budget food accordingly.
  3. Use short, repeatable trips while learning; offensive prayers speed kills but consume supplies.

Exact 28-slot starting inventory

Direct melee · food-based trips. Read this as a conservative starting bag, not a guaranteed trip length.

Wear valid smoke protection. This is a conventional food layout, not a Redemption or freeze strategy. Protection prayers do not prevent the typeless damage.

Equipment and budget

The interactive armoury recommends a curated, boss-appropriate equipment progression within the bankroll you enter. It also shows worn slots, item statistics, live quoted values and the inventory cost separately. It is not a maximum-DPS simulator, and it cannot verify your levels, quests, charges or unlocked travel routes.
