A player battles against the Thermonuclear smoke devil.

The thermonuclear smoke devil is a boss variant of the regular smoke devils, requiring 93 Slayer to kill. Similarly to Kraken, despite its high requirements, the boss fight is mechanically simple and kills are quite quick, reaching 60–100 kills per hour depending on gear and strategies used.

Requirements[edit | edit source]

  • Level Slayer 93 to deal damage against the thermonuclear smoke devil.

Recommendations[edit | edit source]

  • High combat stats. Although not required, see the skill levels below for an indication of the advised stats:
    • If using Melee:
      • Level Attack 90 or higher
      • Level Strength 90 or higher
      • Level Defence 90 or higher
      • Level Hitpoints 90 or higher, required to utilise the Redemption prayer method
      • Level Prayer 70 or higher for the Piety prayer
    • If using Magic:
      • Level Magic 75 or higher to equip the correct staves
      • Level Hitpoints 90 or higher, required to utilise the Redemption prayer method
      • Level Prayer 49 or higher for the Redemption prayer

Getting there[edit | edit source]

Smoke Devil Dungeon map.png

The thermonuclear smoke devil is located in a separated section of the Smoke Devil Dungeon, as seen on the image. The quickest way to get to this dungeon is via fairy rings:

  • Use the code BKP, then run north east to the dungeon entrance.

If fairy rings are not unlocked, teleport to Castle Wars and run southwest of the building, where the entrance to the Smoke Devil Dungeon is.

Run northwest after entering the Smoke Devil Dungeon to find a crevice leading to the section with the thermonuclear smoke devil.

Mechanics[edit | edit source]

Attack styles[edit | edit source]

The thermonuclear smoke devil only attacks with a typeless magical ranged attack:

  • 'Typeless' means that protection prayers will not have any effect.
  • 'Magical ranged' means that the attack accuracy is decided by the ranged attack bonuses of the thermonuclear smoke devil and the magic defence bonuses of the player.
  • The max hit of this attack is 8.
  • The attack is very accurate and has an attack speed of 2 ticks (1.2 seconds).
  • The attack range is eight tiles.

Smoke[edit | edit source]

The thermonuclear smoke devil is located in a smoky environment. Therefore players must equip either a facemask or slayer helmet. If none of these items are equipped, the thermonuclear smoke devil will quickly drain the player's hitpoints and stats.

Tips[edit | edit source]

Safespotting[edit | edit source]

The player's magic spells have a longer attack range than the thermonuclear smoke devil. This difference may be utilised by freezing the thermonuclear smoke devil and then moving out of its attack range, so that the player can still attack the thermonuclear smoke devil, while the thermonuclear is not able to reach the player. Powered staves require the use of the longrange attack style for this method.

The thermonuclear smoke devil can be frozen by using the ice spells of the Ancient Magicks spellbook.

Redemption method[edit | edit source]

Players with a Prayer level of 49 or higher are able to make use of the Redemption prayer. The Redemption prayer can be used at the thermonuclear smoke devil as a way of restoring hitpoints. When the player's hitpoints are reduced below 10% of their maximum hitpoints while the Redemption prayer is active, the Redemption prayer will use the player's remaining prayer points to heal the player. The number of hitpoints healed is equal to 25% of their Prayer level (rounded down).

After the Redemption effect is triggered, the player will have to quickly restore their prayer points by drinking a dose of a prayer potion or super restore and reactivate the Redemption prayer.

Players with a Prayer level of 96 or higher are able to restore 24 hitpoints with the Redemption prayer. Since a prayer restore potion has four doses, each potion could potentially heal 96 hitpoints, which is significantly higher than the best healing regular food (which restores 22 hitpoints).

Since the maximum hit of the thermonuclear smoke devil is 8, the player should have always stay at at least 9 hitpoints while utilising the Redemption prayer method, to reliably survive all of the thermonuclear smoke devil's attacks. Therefore it is highly recommended to have a Hitpoints level of 90 or higher, to make sure the Redemption prayer always gets activated when the player gets damaged below 9 hitpoints.

Walk-under method[edit | edit source]

The player's attack speed is slower than that of the thermonuclear smoke devil. For every attack of the player performs, the thermonuclear smoke devil performs 2 to 2.5 attacks. When walking under the thermonuclear smoke devil immediately after performing an attack, the player is able to hide from the thermonuclear smoke devil's attacks until they step out to perform another attack. When utilising this method correctly, the thermonuclear smoke devil will only perform 1 attack for every attack the player performs; therefore reducing the damage taken by 50 to 60 percent.

A more advanced version of the walk-under method utilises the fact that NPCs do not move when the player they are targeting is underneath them if the player clicks on an item on the ground or an interactive object (producing a red 'X' when clicked). If an item, such as the ashes that the boss drops every kill, is under it or on the opposite side of the boss from the player, it is relatively easy to walk under the boss and attack on a constant rhythm. This works even with the left-click attack option on. This is easy to do if the item is under the boss' hitbox and not under its clickbox, or if the item is on the opposite side from where you are attacking; simply kill the first one as normal with the walk-under method, then drop the ashes in the south-west corner of the boss' hitbox where it normally spawns. If done correctly, after the next kill, more ashes will be dropped in the exact same tile and you do not have to drop more.

Notes[edit | edit source]

  • If not using a scythe of vitur, the recoil damage from a charged ring of suffering (i) ends up dealing more damage than a berserker ring would help achieve.
  • The strength bonus from Bandos chestplate is only worth the extra damage taken if using a scythe; otherwise, armour with high magic defence is recommended for longer trips.
  • Bandos tassets usually do not help achieve a damage boost and thus are not worth for most of the kills, although they are recommended to bring for dragon claws' special attack.
  • An imbued heart is recommended to increase Magic level, which subsequently increases magic defence.
