Firestorm

Required	Fire Sphere 5
Range	Rank x 50 yards
Area	Rank x 5 yards radius
Duration	Full Round Concentration + 1 round
Casting	Verbal, Somatic
Cast Action	Full Round
Mana Cost	4 Mana
Effect	The caster summons a swirling vortex of fire in the targeted area which limits visibility to 2 yards and deals Intelligence + Magecraft + Sphere fire damage every round to everything in the area. To maintain the spell the caster must spend their Full Round action concentrating on the spell. If they move, or cast another spell, Firestorm will persist for 1 additional round before ending. Gale force winds twirl, laced with significant amounts of magical fire. Natural cloth and papers are incinerated, wood bursts into flame, unprotected stone and metal begin to slag, and water boils rapidly. Any flying creatures are affected as if by any other storm, and physical projectile attacks lose an additional attack die for every 2 yards of travel through the storm, in addition to any sight-based penalties. Breathing becomes difficult as air is consumed by the fire, and creatures which require air to breathe that are within the storm take an additional 1 non-lethal from the suffocation in the 2nd and subsequent rounds.
