This more powerful version
of the affect normal fires spell enables the caster to quickly
extinguish a large fire. When the spell is cast, anti-energy
from the quasi-plane of ash is momentarily drawn down
upon the fire. An area of non-magical fire up to 10 feet by
10 feet per level of the caster can be put out in just one segment,
so the spell is ideal for combatting forest and brush
fires. The spell is less effective against magical fire. The
chance of extinguishing a magical fire is only 60%, and a
maximum area of 10 yards by 10 yards, regardless of the
level of the spellcaster, can be snuffed. The spell has no
effect on a fire-based creature or flames emanating from a
creature’s body, such as fire elementals, fire grue, or the
type VI demon.

MC: A pinch of cold ash mixed with salt.
