In-Game Description
Primal pyromancy taught by Quelana of Izalith.'Erect fire pillars in vicinity.'The storm of flame is indiscriminate,and incinerates all nearby life. ==Availability==*Sold by Quelana of Izalith in Blighttown for 30,000 souls.

General Information
Firestorm has twenty "uses" per slot. A full cast of Firestorm will expend 17 of these "uses"; attempting to cast Firestorm again will result in a much weaker spell. Using Firestorm causes many (17 in a full cast) pillars of fire to erupt from the ground in a large area around the player. The spell has deals very high damage and most enemies that get hit by it will be knocked back, possibly into another flame pillar.

Firestorm has a very long windup time that can be shortened through improving the Dexterity stat. It may be canceled or interrupted if the caster is hit, in which case not all 17 casts will be used.

Despite its description, Firestorm will not deal damage to allies. It will, however, damage neutral characters such as merchants.

Overview
Firestorm is popular for its dramatic effect and its high damage. It is a high-risk, high-reward pyromancy to use in PvP due to its very high damage but its lethargic cast time.
