Transmute Liquids

You dip your hand into a volume of non-magical liquid up to 10 gallons, such as ale, water, blood, oil, wine, or even acid. The liquid is transformed into another common, non-magical liquid of your choice worth 10 gp or less. If used against a creature composed of liquid, ooze, or slime, make a melee spell attack. A hit deals 3d10 force damage.
