This spell instantly snuffs all flames of a nonmagical nature within the area of effect. Burning items are not destroyed and may be relit if another source of fire is applied to them. Burning items within the area of effect are snuffed even if they are in any sort of normal container that would protect them from wind or water. Magical flames of a continuous nature are extinguished for one round and then relight. Flaming breath weapons that enter the area of effect during the same round as the spell is cast have their damage reduced by 1 point per level of the spellcaster. Light, continual light, and other similar spells are unaffected by banish flame.
Notes: Granted by Kossuth, a greater power of the elemental plane of Fire.
