Thunderfire is a legendary laser manufactured by Maliwan and is exclusive to The Claptastic Voyage DLC for Borderlands: The Pre-Sequel. It is obtained randomly from any suitable loot source but has an increased chance to drop from Despair and Self-Loathing located in Subconscious.

Special Weapon Effects

Light 'em up. – Always shock. Increased continuous damage bonus. Laser bolts create an incendiary nova upon collision with a solid object or an enemy. Reduced fire rate. Consumes two ammo per shot.

Usage & Description

The Thunderfire is an excellent weapon against flesh enemies with shields because they quickly start to suffer both elemental effects; the shock damage quickly depletes their shields while the incendiary novas ignite them. Moreover, because of its shock properties, shooting an oxygen generator will turn it on, allowing the fire novas to ignite enemies inside it for additional damage if there wasn't an atmosphere already. The Thunderfire is only effective against armored enemies as a shock weapon as the incendiary nova will be resisted.


  • Due to the elements used, Athena can easily gain Maelstrom stacks at twice the rate, even more if the nova hits multiple enemies.
  • The damage dealt by the Thunderfire has a significant discrepancy from the value listed on the weapon card. The shock attack deals 111% of the listed damage value, while the incendiary attack deals 85% of the listed value.
    • When accounting for elemental multipliers in Ultimate Vault Hunter Mode, a direct hit will deal 312% of the listed damage to shielded targets, 260% against flesh, and 145% against armor.
  • The Thunderfire can spawn with any sight, stock, grip, or Lunehsine bonus, but the prefix does not appear in the weapon's name.
  • As both Despair and Self-Loathing have an increased chance to drop it, it is possible, though rare, for two Thunderfires to be dropped in a single encounter.


  • Thunderfire is one of the few weapons that utilizes multiple elements simultaneously but only lists one of them.
