Quench is often used to put out forest fires and other conflagrations. It extinguishes all non-magical fires in its area. The spell also dispels any fire spells in its area, though you must succeed on a dispel check (1d20 +1 per caster level, maximum +15) against each spell to dispel it. The DC to dispel such spells is 11 + the caster level of the fire spell.
Each elemental (fire) creature within the area of a quench spell takes 1d6 points of damage per caster level (maximum 15d6, no save allowed).
Alternatively, you can target the spell on a single magic item that creates or controls flame, such as a wand of fireball or a flaming burst sword. The item loses all its fire-based magical abilities for 1d4 hours unless it succeeds on a Will save. (Artifacts are immune to this effect.)
