- “A stone slab inscribed with peculiar characters. Once it conferred wisdom on many.”

The Rosetta Stone (ロゼッタいし, Rozetta Ishi?) is a recurring item in the Final Fantasy series. Appearing as an important Key Item in the first original Final Fantasy, it is related to learning new abilities.
- “A tablet inscribed with ancient writing.”
The Rosetta Stone, also known as the Slab, is a key item that is found in the Sunken Shrine. Bringing it to Dr. Unne in Melmond will enable him to teach the Warriors of Light Lefeinish, thus, allowing contact with the ancient Lufenian civilization, holder of the Wind Crystal.
The Rosetta Stone is a GF ability item that can teach a Guardian Force the "Ability x4" ability allowing a character junctioning the GF equip four support abilities at once. Rosetta Stones are rare and only a few can be found in the game. It is a very rare reward for playing a prisoner at Triple Triad in D-District Prison. The one who charges 200 gil has a chance of giving out a Rosetta Stone. One can be obtained by repeatedly accessing Cheryl's Shop in Esthar City; the shop is closed, but eventually gives out a Rosetta Stone if the player attempts to access the shop.
Finally, there is one Rosetta Stone in Ultimecia Castle: the player must open the gate right from the fountain area by pressing all the keys of the organ simultaneously to rid of the bars barring the entry to enter the sewers. To drain the sewers of water, the player needs to find the Floodgate key by using the elevator found in the castle. The player must place a lighter party to the left side of the elevator and switch to the other, heavier, party, which is moved on the right side of the elevator.
Switching party at this point allows the party to access a secret room with a Curaga Draw Point and the Floodgate Key. Lighter party is achieved by having a party with at least two females in, as long as the lone male isn't Irvine. The Floodgate Key is used in the lever in the prison, right next to the door that leads to Red Giant's chamber.
Rosetta Stones can be obtained in the shop, as storyline bonuses, and in the Blackjack course of Duel Colosseum. They can also be traded for one each of a Wind Stone, Water Stone and Life Stone. They can be exchanged for a Command Mode AI boost skill or accessory slots in the shop.
- “A stone necessary for warrior to strengthen themselves. Try asking at the shop.”
It is named after the famous slab containing Egyptian hieroglyphic, demotic, and Greek text, that was discovered in Egypt in 1799 and deciphered by Jean-François Champollion. Like the Rosetta Stone of the original Final Fantasy, the Stone was instrumental to deciphering the lost language of Egyptian hieroglyphics.
