You extinguish all fires in a 30 foot cube centred on a point you choose within range. Any nonmagical fire is put out automatically, as are magical flames created by a spell of 3^rd level or lower. For each spell of 4^th level or higher which is creating flame within this area, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a successful check, the spell that created the fire ends.

Fire created by a magical item is also doused, and the item becomes unable to produce fire for 1d4 hours. Artifacts are immune to this effect.

Fire-based creatures in the spell's area, such as fire elementals, must make a Constitution saving throw, taking 8d6 cold damage on a failed save or half as much on a success.
