The Thermonuclear smoke devil is a boss variant of the normal Smoke devil, requiring 93 Slayer to kill. As it is also in the Stronghold Slayer Cave, they can only be killed when given a smoke devil task. It is not as popular as the Kraken, as its common drops are less valuable, but it is still killed for those seeking the Smoke battlestaff or pet smoke devil.
How to get thereEdit
Follow the path to the Fire giant area. There will be a crevice in the first fire giant room to the side, which leads to the smoke devils. Upon entering, toggle the smoke off (to see clearer) and run northwest from the smoke devil chamber to find another crevice leading to the boss' chamber.
The Thermonuclear smoke devil only attacks with magical ranged, so bringing ranged armour such as Karil's will help reduce the accuracy of the boss' hits. Despite the fact that the Thermonuclear smoke devil has a max hit of 8, which is very low for its level, it makes up for this with an attack speed of 8 (1.2 seconds inbetween attacks), and is very accurate, even with good range armour on.
Like their dust cousins, a Face mask or equivalent (slayer helmet) is required, as failure to do so will result in the Thermonuclear smoke devil dealing rapid damage and draining the player's stats, and the smoke environment will damage the player.
The Thermonuclear smoke devil is weak to melee attacks, specifically slash. While it is relatively weak to all forms of melee, its lowest defence is in slash (+4 slash, +9 crush, +11 stab); however, it does have a high defence level of 360. Magic can also be used, despite its magic defence of +800, as an NPCs actual magic defence rolls on its magic level, not its defence level (and any magic bonuses). Ranging is not recommended due to its high defence and ranged defence bonus (+900 ranged defence).
The normal setup is used to fight the Thermonuclear smoke devil at a reasonable kill rate with minimum input put into supplies.
Since the Thermonuclear smoke devil is incapable of dealing hits over 9 damage, another way to kill the boss for a longer trip (but at a higher supply cost) involves the Redemption prayer, which will heal you when you fall below 10% of your maximum hitpoints. Since the boss has a max hit of 8, you will need at least 90+ Hitpoints, or you risk the possibility of getting killed rather then having Redemption activate instead.
- Saradomin godsword (use a dragon or crystal halberd if you cannot afford it)
- 1 Super strength and attack potion
- Emergency teleport (to escape)
- Rest of inventory spaces to be filled with prayer potions (you may want to leave 2-3 slots empty for picking up items)
Magic is another way to fight the Thermonuclear smoke devil. Despite its magic defence of +800, its Magic level of 1 means that much like Karil the Tainted and the Crazy archaeologist, its magic defence is very poor. Since magic robes can result in a lot of damage due to its magical ranged attack, farcasting is recommended to reduce the amount of damage you will take fighting the boss.
