Final Fantasy I Walkthrough

8. Exploring with the Mystic Key

Now, the next stop is Mt. Duergar, but there are many unopened treasure chests around the world that you can now get to with the Mystic Key.

We’ll start in Elven Castle, where you can find a Mythril Hammer, Bronze Gloves, and 730 gil in four chests behind the castle.

In Cornelia Castle, you can find a Crosier, Saber, Mythril Knife, Steel Plate, Iron Shield, and Nitro Powder. Getting this now will save you some time back at Mt. Duergar.

In the Temple of Chaos, you can find a Rune Blade, Werebane, and a Gold Needle.

Back on the Elfheim continent, you can find the Falchion, Power Staff, and Steel Gloves at the Western Keep.

Finally, in the Marsh Cave, you can find 1020 gil, a Mythril Knife, and a Silver Armlet.
