transform water

You touch a volume of water up to 1 pint, and it changes into an equal volume of flammable liquid similar to alcohol or poison, or acid. A 1-pint flask of tjis can be splashed, thrown or poured on the ground – and ignited – as though it were a flask of oil for the flammable stuff. It can also be ignited with lightning damage.

When the duration of the spell ends, the liquid – and any fire caused by it – evaporates completely.

The volume of water that can be transmuted increases to 2 pints at the 5th level, 4 pints at the 11th level, and 1 gallon at the 17th level.
