No material components. No gestures. Just a complicated guttural verbal component. Many wizards have tried to reduce this spell to a cantrip. However, it doesn't seem to be possible to reduce the verbal component enough to do this. Perhaps adding a small somatic gesture?
Each casting halves the volume and effectively doubles the percent alcohol in the liquid it is cast upon. The catch is that the water goes first. Thus, if beer containing 10% alcohol is placed in the pot, then it will lose half its volume, but will now contain 20% alcohol. When all the water is gone, some other liquid (juice, etc.) has to go next (DM's choice).
Effects are similar to Darkblood's travel size distillery (see the Net Alcohol Guide for more information on this item). In fact, this is one of the spells Darkblood used in creating his distillery.
This spell has no effect on any living being, except (perhaps) water elementals. This is up to the DM. For example, the water elemental must save versus spell or lose half its remaining hit points when struck by this spell. A successful saving throw indicates half damage or loss of fourth of the remaining hit points. This is clearly a very powerful spell against water elementals, but how many times does one see water elementals? If this is a problem than simply rule it doesn't affect water elementals either, or lower the damage it causes.
