Key that opens magically sealed doors.


The Mystic Key (しんぴのかぎ / 神秘の鍵, Shinpi no Kagi?) is a key item in the original Final Fantasy that opens various doors in the early portions of the game. It is given to the Warriors of Light by the Elven Prince of Elfheim after he is awakened from the spell of Astos.

The party uses the Mystic Key it to recover explosives from Castle Cornelia to give to the dwarves so that they may gain access to Melmond. Other rooms opened by this key generally contain treasure chests with powerful weapons or armor for that point in the game, or large amounts of gil.

Rooms opened by the Mystic Key can be found in Castle Cornelia, the Chaos Shrine, the Western Keep, the Marsh Cave, the Elven Castle, and Mount Duergar.
