Fellstar's Flame Fog
(Evocation)

Range:  10 yards
Components:  V, S, M
Duration:  1 round per level
Casting Time:  7
Area of Effect:  40-foot wide, 20-foot high, 20-foot deep cloud
Saving Throw:  1/2

This spell creates a fog resembling that produced by a cloudkill; the cloud may be created up to 10 yards away, and moves 10 feet per round as directed by the caster. Strong winds will move the cloud in another direction, but will not disperse it, nor will they move the cloud back towards the caster. Thick vegetation will break up the cloud in 3 rounds. The fog itself is not harmful, and has no other effect besides obscuring vision. During any round after the spell is cast, the caster may ignite the fog with a single word. When this is done, the entire fog cloud becomes a roaring sheet of flames inflicting 5d10 points of damage, plus 1 point per level of the caster (up to a maximum of 5d10+20) to those caught inside. A successful saving throw versus spell reduces the damage by half. Those victims who fail their saving throws must roll for all their possessions versus magical fire; those items that fail their saving throws are destroyed.
If any type of fire comes into contact with the fog cloud, it ignites immediately; if a fireball or similar spell is cast into the cloud, the damage inflicted is cumulative, and a saving throw for each effect must be made separately. The material components for this spell are several strands of hair from a cloud giant, and the scales of a red dragon; all components are consumed when the spell is cast.
