Overview

Hellfire is a Submachine Gun that focuses on dealing Incendiary Damage. Compared to other similar Weapons, Hellfire's Incendiary status is significantly stronger.

If you're playing a status-based build, Hellfire is a great asset for dealing with red health bar enemies.

Farm Method:

  • Defeat Skyspanner Kratch inside the Lambent Mine.

Synergies & Best Builds

As a purely Incendiary damage gun, the Hellfire works great against enemies with Flesh (red) health bars, doing up to 75% extra damage

Elemental damage modifiers such as Harlowe's Elementary and Periodic Table Flip will increase this guns' damage.

Vex benefits from Incendiary specifically, being able to attune to it and also skill into Burnt Offering which grants more elemental damage than most other modifiers, albeit only for Incendiary.
