Exotic Armour

The Exotic Armour, found in Ultima III, is the only armour that can adequately protect the party in the Castle of Fire.

During the quest through Sosaria, the Stranger's party had learned that the monsters in Exodus' castle were so horrible, only the Exotic Armour could protect from their attacks. Having received several hints, they found the armour buried on the west side of a small island to the east of Grey. Equipped with them, the party managed to advance through all resistance, finding Exodus in the end.

Trivia

 * It is not entirely clear if the Exotic Armour are the same as the Mystic Armour found in Ultima IV.
