This spell creates a zone where magical fire effects twist and lash out against those who create the effects. A zone of foul flames looks unremarkable to the casual observer, but a Perception check (DC = 20 + the caster’s level) reveals a faint rippling effect in the area, as if of heat distortions in the air.
Whenever a creature casts a spell with the fire descriptor or activates a magical fire effect (as from a magic item or a special attack) while that creature is located in a zone of foul flames, that creature takes full fire damage from the effect. If the effect allows a saving throw to reduce the damage, the victim may attempt the same saving throw to reduce the damage. All creatures in a zone of foul flames gain a +4 circumstance bonus on all saving throws against fire effects, except for those made by a creature attempting to save against fire damage from his own magic. Nonmagical fire in a zone of foul flames burns half as brightly but is otherwise not affected.
