Aggy's Everfull Mug of Mead

From Ardrana

Aggy's Everfull Mug of Mead was a magic item carried by Aggy, an aasimar priest of Perasin. No one is quite sure how he got hold of it, though some wished he never had. The item performed exactly as described, filling with mead on command as often as its owner wished. Sadly (or perhaps not), it was never recovered after Aggy's death, so its current whereabouts are unknown.
