— In-game description

Flamethrower is an action unlocked by questing at level 70. It is available for Machinist.

Notes

• This action hits for a total of eleven times – once initially, and once every second thereafter. The total potency of this action is 1320, assuming it has been channelled in its entirety.
• This action, similar to all damage over time effects, will be snapshotted by raid buffs, excluding debuff-based raid buffs like Dokumori and Chain Stratagem.
• Because this action does not generate heat, machinists may consider the following scenarios when optimizing damage:

• Flamethrower should never be prioritized over Hypercharge, Chain Saw and Excavator, or Drill or Bioblaster.

• An exception for Hypercharge is if a group of enemies are about to be defeated before another group (i.e. trash mobs in a dungeon). In this case, Flamethrower is preferable on two or more targets.
• If Hypercharge is not available, Flamethrower is preferable on two or more targets over Scattergun and the Heated Clean Shot combo.

• Flamethrower is preferable to Air Anchor if there are six or more targets. This is because of the battery Air Anchor generates.
• Flamethrower is thus a gain on two or more targets over the Heated Clean Shot combo when all multi-tools are on cooldown. To maximize the time spent while executing Flamethrower, it is best to channel it as soon as possible after all multi-tool actions have been executed. Machinists should still be weary of mechanics or incoming AoEs, as Flamethrower will be cancelled upon any movement or actions, as it is a channeled action.
