Description
You can take a Magic action and name one liquid from the Alchemy Jug Liquids table to cause the jug to produce the chosen liquid. Afterward, you can uncork the jug as a Utilize action and pour that liquid out, up to 2 gallons per minute. The maximum amount of liquid the jug can produce depends on the liquid you named.
Once the jug starts producing a liquid, it can't produce a different one, or more of one that has reached its maximum, until the next dawn.
