Mystic Weapons

The Mystic weapons are the only weapons that work in The Abyss in Ultima IV and in dungeon Doom in Ultima V.

The Mystic Weapons were first found by the Stranger and the Companions, after all eight Shrines gave the Stranger partial Avatarhood. Going after several clues, these special swords were found in Serpent's Hold, in a secret place under the training hall. With the help of these weapons, they managed to finish off 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. These weapons again proved their worth, taking down the foes in dungeon Doom.

It is unknown, what happened to them after this.
