List of Rare items

A list of all key items classified as Rare items. Also see the list of Important items. The three Class-changing items, Mysterious Card, Trainer's Whip, and Tomegathericon are all also categorized by the game as Rare items. The primary difference between a Rare item and an Important item is that rare items can be sold, and the more important rare items in general are counted as Artifacts that mean they can be bought back at a later date.

Rare items in Golden Sun
Empty Bottle: "Extracts water from a magic spring": Found in a chest in Imil. When used at the well at the entrance of Mercury Lighthouse, it will be filled with Hermes' Water. It empties if an Adept uses the Hermes' Water.

Hermes' Water: "Replenishes all HP": Has the exact same effect as a Potion. When used it empties itself, and can be refilled at the fountain in Mercury Lighthouse. Thus, it can be refilled unlimited times.

Cell Key: "The key to the cells in Lunpa Fortress": An item that causes any cell door in Lunpa Fortress to open up, except for the cell door in which Dodonpa is confined in after the completion of the Lunpa Fortress side quest.

Rare items in The Lost Age
All the key items in the first game return either officially or, more commonly, inaccessible but coded for the sake of preventing glitches.

Large Bread: "Nourishing bread that fights hunger": Findable in a small storage room in the sailing ship while it is docked at Alhafra. Give it to a hungry kid in town and the boy's father, guarding the northwestern entrance to Alhafran Cave, will allow you to explore it.

Laughing Fungus: "A rare and suspicious mushroom": Findable in Gondowan Cliffs. It does not have any ultimate use other than to sell for 525 coins.

Healing Fungus: "A rare and delicious mushroom": Findable in Gondowan Cliffs. Give this to an old couple in Madra to get a Mars Djinni in return.
