Everlasting Goblet

The Everlasting Goblet has the surprising ability to be never empty, meaning that the person possessing it will never again complain of thirst. However... the Goblet is quite small, meaning that someone has to drink from it many times to still the thirst. It is found in Ultima VII Part Two

Description
The Avatar found the Goblet in the ruins of Furnace. If failing the test, Lord Zhelkas demanded the Goblet for passage. Otherwise, it stayed with the Avatar.

Trivia

 * You could use the goblet to feed your party. However, its low feeding value makes this too much of a hassle. Using the spell Create Food together with the Ring of Reagents is more economical.
