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 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. It works fairly well against armored enemies too because of the shock element, but the incendiary novas created on impact are ineffective against armor.
The damage dealt by the Thunderfire has significant discrepancy from the value listed on the weapon card. The actual shock laser-bolt deals about 111% of the listed damage value, while the incendiary nova 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, and the fire damage will hit enemies in an area of effect the size of a small grenade, further stacking the overall damage output of each shot.
