List of Important items

A list of all key items classified as Important items. Also see the list of Rare items. The primary difference between an Important item and a Rare item is that important items cannot be sold or dropped, and only enter and leave the party's inventory in response to storyline events.

Key items in Golden Sun
Mythril Bag: "A fine bag made of mythril": You get four of these at Vale when Kraden decides to accompany you to the Sol Sanctum dungeon. Each one is "replaced" by the Elemental Stars below in Sol Sanctum in response to storyline events. Mythril Bags containing the Stars also appear in The Lost Age.

Small Jewel: "A beautiful eye-shaped jewel": A dungeon-specific item which you get two of in Sol Sanctum. Both Small Jewels are used for puzzle-solving.

Venus Star: "Earth Elemental-requires Mythril Bag": The Elemental Star of Earth. It is in your party very briefly in the Elemental Star Chamber.

Mercury Star: "Water Elemental-requires Mythril Bag": The Elemental Star of Water. It is in your party very briefly in the Elemental Star Chamber.

Jupiter Star: "Wind Elemental-requires Mythril Bag": The Elemental Star of Wind. It is in your party so briefly in the Elemental Star Chamber it might as well never be collected at all, for as soon as you get it a cutscene occurs where you lose it and the above three stars. It is "present" in Felix's party in The Lost Age for much of that game, hidden within one Mythril Bag.

Mars Star: "Fire Elemental-requires Mythril Bag": The Elemental Star of Fire. Unlike the other three Stars, this one stays in Isaac's party for the entire game, and close to the end of The Lost Age it returns to the party's inventory.

Dragon's Eye: "A shining red jewel with flames inside": Similar to the Small Jewel, a Dragon's Eye is used within a specific dungeon, Fuchin Falls Cave, for puzzle-solving. After it is found in a treasure chest, it is inserted into a dragon statue that then spits fire to light up the room, revealing an invisible pathway by revealing its shadow.

Bone: "A bone from the girl at the inn": Obtained from the inn at Vault. Give it to the dog at the elevated south portion of the town and it will move up a bit, and mind-reading it tells you that using the Reveal Psynergy here will reveal something special, which is the path to the Vault Cave dungeon. Another bone appears in The Lost Age when dug up out of Lemuria.

Boat Ticket: "A ticket needed to cross Karagol Sea":

Anchor Charm: "A trinket in the shape of an anchor":

Mystic Draught: "A strangely colored mysterious potion": In The Lost Age its description coded into the game is "A strangely colored potion".

Black Orb: "Controls the ancient ship": Known in The Lost Age as the Black Crystal.

Blue Key: "The Blue door key from Crossbone Isle": In Golden Sun four of this key is collected and used for puzzle-solving in the third floor of Crossbone Isle. In The Lost Age one of this item is used in Jupiter Lighthouse, and its desctiption in that game is "Key to blue door in Jupiter Lighthouse".

Red Key: "The Red door key from Crossbone Isle": In Golden Sun one of this key is collected and used for puzzle-solving in the third floor of Crossbone Isle. In The Lost Age another one of this item is used in Jupiter Lighthouse, and its description in that game is "Key to red door in Jupiter Lighthouse".

Key items in Golden Sun: 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.

Aquarius Stone: "The stone that leads the chosen one": Found in a chest within Aqua Rock's interior dungeon. When placed on the plinth in the center of Aqua Rock it parts the waterfall blocking the door to the chamber containing the Parch Psynergy tablet. Once placed on the plinth the stone cannot be picked up again.

Center Prong: "The center piece of a trident": Found in Tundaria Tower encased in ice. To remove the ice surrounding it you must first get the Burst Brooch from the top of the tower. Burst breaks the ice and the Center Prong is added to your inventory. Take it to Obaba in Champa along with the other two peices to forge the Trident of Ankohl. Often the second piece found as you need Parch and Burst to obtain it.

Left Prong: "The left tine of a trident": Found at the top of the Ankohl Ruins after completing the puzzles below. Take it to Obaba with the other two peices to forge the Trident of Ankhol. Often the last piece found as the ruins are close to Champa.

Right Prong: "The right tine of a trident": Found at the top of the Shrine of the Sea God after completing the puzzles below. Take it to Obaba with the other two peices to forge the Trident of Ankhol. Often the first piece of the Trident found as the Shrine is close to the Lemurian Ship.

Key Items in the Series
Shaman's Rod: While technically a weapon, the Shaman's Rod essentially becomes an unusable key item after the player progresses as far as the second or third town in both Golden Sun games. This is due to its low Attack stat increase (+10) and lack of an unleash. It cannot be dropped or sold, like all other key items. It plays an important role in the overall plot, being utilized as a sort of bargaining chip several times.
