Firestorm creates a series of blazing explosions over the enemy wave, hitting all foes three times for moderate Fire damage. While less powerful than Bullet Hell, it spreads out the damage evenly.
In EBF3, Firestorm is able to lower the Defence of targets at its final level. This ability is removed in later games in favor of the ability to Burn targets.

Like many other Fire elemental skills, Firestorm can now inflict the newly introduced Burn status effect on targets. Firestorm can no longer inflict a Defence debuff at any level.
