Mystic Armour

The Mystic Armour is the only armour that affords protection in both the Stygian Abyss in Ultima IV and the dungeon Doom in Ultima V.

The Mystic Armour was first found by the Stranger and Companions, after all eight Shrines gave the Stranger partial Avatarhood. Going after several clues, they were able to get their location from Sir Simon. These special robes were found in Empath Abbey, in a secret place in the Oak Grove. With the help of this armour, they managed to withstand the foes that blocked their way in the Abyss.

Thought lost after this, the Avatar found them again in the Underworld in Ultima V, in a lava pool under the Abyss, near the dungeon Hythloth. This armour again proved its worth, protecting against the foes in dungeon Doom.

It is unknown what happened to it after this.

Ultima VI Project
In the The Ultima VI Project, the Mystic Armour could again be found in the basement of the Lycaeum.
