Final Fantasy III (Nintendo DS)

The lost third game in the Final Fantasy series finally comes to America and Europe! Unfortunately, it was given an awful new difficulty curve and flat, uninteresting characters, both of which were an improvement.

Desch's Sword
Used by Desch while he is in your party. Cannot be equipped by any class (including the Onion Knight), but can be thrown. Its description reads "Desch's personal sword."

Adaman Sword
It's spelled that way in the code. Completely unused. Can be thrown. Has an Attack of 138, placing it in the endgame. Cannot be equipped by any class, judging by this and its attack value, was it meant to be an Ultimate Weapon for a prototype class?

Shadowflare
Normally used with the Geomancer's Terrain command. Level 8. Cannot be used by any class (probably for the best, as this would break the game if it could be used at will). Uses the bell icon in the item menu and the "dead" status icon in the magic menu (for some reason), and has a description: "Deals non-elemental damage."
