Exotic Armour

The Exotic Armours, found in Ultima III, are the only armours 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 Armours could protect from their attacks. Having received several hints, they found the armours buried on one of the small islands of Sosaria. 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 Armours are the same as the Mystic Armour found in Ultima IV.
