The design was submitted by a solarium tier pre-order backer, who was granted the perk of designing a weapon to be included in the game.
The weapon's long description reads as follows: "According to legend, this flaming blade was forged by fallen angels."
The primary ability is a simple melee slash with a fire time of 1 second and a tier-adjusted base DPS of 30, producing a base hit power of 30. The attack also has a knockback power of 30 (strong knockback).
The secondary ability, Flamethrower (Sword), is a modified version of the Rocket Spear ability possessed by some generated Spears. Like Rocket Spear, Flamethrower (Sword) consumes 45 energy per second to fire flame projectiles using a fire time of 0.065 seconds (approx. 15.4 shots per second) and has a 0.5-second cooldown when the ability ends. Unlike Rocket Spear, Flamethrower (Sword) does not have a propulsion component to it, making it useless as a mobility aid. This ability has a tier-adjusted base DPS of 27. It has an extremely short range under water.
The sword is a reward for defeating the final challenger in the arena side quest Arena of Fire. After turning in the quest the sword will be rewarded.
When upgraded at a Weapon Upgrade Anvil to tier 6, the primary ability's base DPS increases to 35, producing a new hit power of 35; also, the alt ability's base DPS increases to 31.5. Additionally, the appearance of Firestorm's Fury changes to the one shown below.
Apart from the addition of a gold star to the name, no other changes occur as a result of the upgrade.
