This magical device can pour forth various liquids upon command. The quantity of each liquid is dependent upon the liquid itself. The jug can pour only one kind of liquid on any given day. The jug can be used up to 4 times per day, subject to the maximum quantity of the liquid per day. For example, the attuned user could pour 20 gallons of salt water per day. He can do it all at once, making the jug useless until the following day, or he could pour out the 20 gallons over the course of the day until the total poured was equal to no more than 20 gallons - for example, 4 gallons, 4 times during the day. The maximum pour rate is one gallon per round.
There are power words written on the outside of the jug that only the attuned user can see. Each power word is used to pour forth a different liquid.
