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 SunEdit
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 is replaced by the Hermes' Water item. It returns if an Adept uses the Hermes' Water.
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 Golden Sun: The Lost AgeEdit
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.
Lil' Turtle: "A turtle who's far from home": Received from the dog at West Indra Islet after giving it the Milk. Give it to Lonesome George the turtle at Sea of Time Islet to get the ability to enter and exit the secret Islet Cave dungeon.
Magma Ball: "A glowing, red ball of volcanic rock": Found in the further reaches of Magma Rock. Use on the Cannon in Loho to get the cannon installed onto your ship, and this allows you to cross into the Northern Reaches near the end of the game.
