Lord British's Crown

Lord British's crown is located in Lord Blackthorn's castle. It is one of Lord British's Crown Jewels.

In original Ultima V you need to "use" the Crown to wear it, and it doesn't replace any pieces of your characters' armor. While it is worn, all magic cast by anyone near the party other than the party members themselves is completely negated.

In Ultima V: Lazarus the Crown has to be worn by one of the party members as a head piece of armor. It provides 2 defense points and negates all magic cast by anyone but the wearer. The Shadowlords are not affected by the Crown's negation effect.
