Just going through first level cleric and magic user spells to convert for our steampunk session and i came across this (emphasis mine):

By means of this spell, the magic-user changes a volume of water to a volatile, flammable substance similar to alcohol and likewise lighter than water. If this substance is exposed to flame, fire, or even a spark, it will burst into flames and burn with a hot fire. Each creature subject to firewater flame will suffer 2-12 hit points of damage. The firewater created will evaporate and be useless within 1 round, even if it is securely contained and sealed, so it must be utilized (ignited) within 10 segments of its creation. The material components of this spell are a few grains of sugar and a raisin.

Yeesh.
