Final Fantasy Wiki

The Adamant Isle Grotto, also known as Adamant Grotto and Adamant, is a location in Final Fantasy IV and Final Fantasy IV: The After Years. In Final Fantasy IV, a family of small people live there, and the father collects tails.

The father will award Cecil with the Adamantite ore if brought a Rat Tail. This can then be taken to Kokkol's house with the Mythgraven Blade and refined into the Excalibur. After bringing him the Pink Tail dropped from rare enemies known as Flan Princesses, he will give the Adamant Armor.

In the 3D versions, powerful enemies such as the Red Dragon have a slim chance of dropping additional tails, which may be brought to the man at the Grotto for additional Onion equipment:

In Final Fantasy IV: The After Years, the cave appears connected by land to Mythril, and is the first dungeon of the game.


Final Fantasy IV: The After Years[]

17 years after the events of Final Fantasy IV, the cave appears connected by land to Mythril and is much larger, no longer being home to the tail collectors. Biggs and Wedge accompany Ceodore here, and Ceodore must brave the trials of the cave alone to claim his proof of knighthood.
