List of Quest items

Among the many items in the are those that help advance the plot or exist purely to fulfill various side-quests. These quest-related items come in many shapes and sizes, and some even have practical uses besides just getting farther into the game.

It should be noted that some quest items can be sold or dropped, while others must remain in the party's inventory until removed by the events they trigger. The items that can be sold, however, are often Artifacts and can therefore be repurchased.

Quest items in multiple games
Hermes' Water: This vial of water first appeared in the original Golden Sun, during which it behaved the same way as a Potion. After being used, it reverts to an Empty Bottle, which can be refilled at Mercury Lighthouse. Isaac's group use the water to heal Tret and proceed to eastern Angara. In Dark Dawn, Hermes' Water is given to Matthew by Briggs, who in turn got it from Piers. This time it is used to cure the Dream Tree, which eventually leads to an audience with Tret. It can be sold and repurchased in Golden Sun, but cannot be sold or dropped in Dark Dawn.

Disposable
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. Bones can be dropped lest they unnecessarily take up inventory space.

Persistent
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. Shaman's Rod: Obtained after defeating the thieves in Vault in Golden Sun, and appears in Felix's inventory when he joins in The Lost Age. 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 games in which it appears. 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 of the first two games, being utilized as a sort of bargaining chip multiple times. Black Orb/Crystal: "Controls the ancient ship": A device used to control Lemurian boats. The Black Orb found in Golden Sun is tied to Babi's ship and is used (unsuccessfully) to try and move another, similar ship. In The Lost Age, Felix aids Piers in recovering his Black Crystal from Kibombo, which they later use to set sail across the Great Eastern Sea. Blue Key: "The Blue door key from Crossbone Isle": In Golden Sun four of these keys are 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 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".

Sellable
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. 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.

Non-Sellable
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 two 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. 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".

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

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.

Watchtower Key: This key, given to Matthew by Ikan the storyteller after saving his son from Harun Channel, unlocks the entrance to the central Warrior's Hill watchtower, allowing Matthew to acquire the ruins' treasure. Third Eye: The main treasure of Warrior's Hill. Said to "guide the way;" it bestows the Search Psynergy upon Himi, waking her up from her psynergetic-slumber in the process. While the Third Eye bestows Utility Psynergy, it's actually a Quest item until this event is triggered, at which point it disappears from the inventory entirely and merges with Himi's forehead (altering her appearance).

Umbra Map: A relic of Morgal kept safe by its former governor, Lord Kuan, and later, by his son, Ryu Kou, the Umbra Map is an ancient map of Weyard that shows the locations of where the various pieces of the Umbra Gear have been hidden. Ryu Kou gives it to Matthew as thanks for rescuing him and his sister from their ice wreck within the bounds of the Grave Eclipse.

Umbra Goggles: A piece of the Umbra Gear specifically designed for equipping by Beastmen like Sveta, these special, light-absorbing goggles are found within an ice cave in the snowy mountains northwest of Imil Village and Mercury Lighthouse and not far from Kalt Island.

Old Rag: If Matthew and his companions return to Passaj during the Grave Eclipse, they find the town protected by the fortress-like walls formed by the reactivation of the Alchemy Forge; however, the people are running dangerously low on food, and two young men sought to escape the mountain to greener pastures. One died protecting his friend, leaving the young man crawling back into the town with only this rag memento and a rattled brain. When Matthew arrives, the girlfriend of the deceased man is bitter and upset, and may be brought this rag to trigger a chain of events that provides access to the Venus Djinni, Ivy. Cave-Door Key: Kept by Briggs in his sleeping chamber in the Champa caves, this key is used to unlock the Pirate's treasure hidden in a small cave beneath the bridge in and out of the city, including a rare and forgeable Orihalcon.
