Nystul's Expeditious Fire Extinguisher

This more powerful version of the 1st-level wizard spell 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 immediately (50 x 50 feet at 5th, 60 x 60 feet at 6th) to a maximum of 100 x 100 feet. The spell is useful for combating 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 30 feet by 30 feet can be snuffed out.

The spell has no effect on a fire-based creature or on flames emanating from a creature's body, such as a fire elemental, a fire grue, or a balor.

The material components for the spell are a pinch of cold ash mixed with salt.
