Star of Britannia

The Star of Britannia is a magical gem in Ultima IX that increases damage by a random amount during combat.

Description
It can be found south of Trinsic in a cave, as indicated on a map found at the Mathis Mines. The Avatar had to give the star to Bakura in order to learn the final staff-technique.

Trivia

 * The Gem of Death, found in Vasagralem's hut by using the red pentagram on the table, fulfills the same purpose and practically is a replica of the gem.
