List of unacquirable Psynergy

There are some Psynergies that the player may never have access to while playing the games normally. Some are Psynergies that are exclusively used by certain special enemies, and what differentiates these from enemy abilities is that the enemy can be blocked from using them for several turns by being afflicted with a Psynergy Seal. Besides this, it is possible to tell the difference in-game because the battle text says that enemies "use" or "unleash" Enemy Abilities and "cast" Psynergy.

There is also, however, a large amount of Psynergies locked away in the code of both Golden Sun and Golden Sun: The Lost Age that can never be seen during normal play. Such content in video games in general is referred to as "dummied content". When using hacking devices such as Code Breaker Advance, however, these can be acquired and used. Several of them work, but others do not have their effects fully programmed.

Rising Dragon
Rising Dragon is a powerful single-target Psynergy that is only used by Agatio in The Lost Age. It has no in-game description since the player is unable to acquire it without using a hacking device. It uses 37 PP. It materializes as a flaming dragon that erupts from beneath the target's feet, seizes him or her in its jaws, and ascends toward the sky and explodes, sending the adept careening back to the ground. It has a base Mars power of 250.

There are three chances during the story of Golden Sun: The Lost Age for the player to witness Rising Dragon. The first is shown in a battle cut-scene at Jupiter Lighthouse where Agatio uses it to knock out Isaac; the second when he may also use it in the following boss battle where the player fights both him and Karst. The final time the battle against the Flame Dragons in Mars Lighthouse, as these dragons are Agatio and Karst; though, Rising Dragon is only used by the dragon on the left side of the screen. Although there are no more chances to see Rising Dragon in the main story, players may encounter Agatio or his Flame Dragon form in Battle mode.

Meteor Blow
A Mars Psynergy used by Agatio in The Lost Age. It appears as a meteor which quickly enters the atmosphere before smashing into your characters from above. To some extent, it resembles the Meteor summon in appearance, but with a different angle of view and explosion effect. It only appears while battling Agatio. It costs 21 PP to use, does damage equivalent to 35% of the target's HP in addition to having a base Mars power of 120, and has a range of all targets.

Earnest Ply
Earnest Ply costs 12 PP and restores one ally's HP by 1000. It can only target the Star Magician or (if he is not an ally of the caster) on the caster themself. Other than that, It is completely identical to the Pure Ply Psynergy, with the obvious exception of their names. It is used by the Refresh Ball summoned by the Star Magician in The Lost Age. It could also be a mistranslation, and "Earnest Ply" is the Japanese name for "Pure Ply".

Arrow
A?? (commonly referred to as Arrow) is a utility Psynergy hidden only in the game code of The Lost Age. It can be hacked into a character's Psynergy collection with a code like CBA's 82000AA8 009D, which hacks it into Felix's first slot. It is called "Arrow" by players because, as an almost fully coded and animated Utility Psynergy, it resembles and functions as an arrow being magically summoned and shot. When used in the field, an orange and red bow-and-arrow materializes spinning in front of Felix, the bow string is pulled back, and the arrow is shot across the screen a short distance, letting loose purple magic, and it and the bow disappate when the arrow has traveled one inch across the screen. This psynergy, when cast, resembles the actions of both the statues atop Jupiter Lighthouse; whether or not the arrow affects the plug atop the aerie (like the statues did) has been left untested. Although no actual uses for the spell have been discovered in game it can be used to light a torch, and annoy Kraden in one of the game's Debug Rooms. It is possible that The Lost Age was going to feature either some puzzles or minigames involving using the Arrow Psynergy to hit targets. It costs two Psynergy Points, is of the Jupiter element, can be used in Towns, and its description is ???.

Aurora Field
Aurora Field is a battle-only healing Psynergy hidden only in the game code of The Lost Age. It can be hacked into a character's Psynergy collection with a code like CodeBreaker Advance's 82000AA8 012A, which hacks it into Felix's first slot. When checked in the overworld, the Psynergy does not have a unique icon like any normal Psynergy, instead using a red X, and its description consists of one single "?". When it is used in battle, no visual effect occurs; its gameplay effect occurs right away, and it is a rather good one. It completely restores the HP meters of all four current battling Adepts, including those who have fallen in battle; its effect is comparable to the healing effect of the Iris summon, but only for the first four adepts. Some believe it was included in the game cart by the development team to help them test battles with enemies. It costs zero Psynergy Points, is of no element, and its target range is registered as "all".

Charm
Charm is a battle Psynergy hidden in the code of both games. It can be hacked into a character's Psynergy collection with a code like CBA's 82000AA8 0076, which hacks it into Felix's first slot. When checked in the overworld, the Psynergy has no icon, and its description consists of one single "?". When it is used in battle, no visual occurs at all, and the game will immediately report whether the effect has failed or "[Enemy]'s heart has been stolen!". No such status condition as "charmed" exists in the game carts, though, and there seems to be no actual game effect - the charmed enemy will not do anything different. After a few turns, however, the game will report that "[Enemy] regains consciousness!". The spell is of the Jupiter element, costs 9 PP, and has a range of 1.

Confuse
Confuse is a battle Psynergy hidden in the code of both games. It can be hacked into a character's Psynergy collection with a code like CBA's 82000AA8 0075, which hacks it into Felix's first slot. When checked in the overworld, the Psynergy has no icon, and its description consists of one single "?". When it is used in battle, the visual it produces is exactly identical to that of the Delude Psynergy. For each enemy, the game has a chance to report that it has been "confused", but no such status condition exists in the game cart; no "confused" visual appears to indicate a status condition, and the enemy will do nothing differently at all. The spell is of the Jupiter element, costs 6 PP, and has a range of 3.

Magnet
Ma???? (commonly referred to as Magnet) is a utility Psynergy hidden only in the games code of The Lost Age. It can be hacked into a character's Psynergy collection with a code like CBA's 82000AA8 009B, which hacks it into Felix's first slot. It is called "Magnet" by players because, as an almost fully coded and animated Utility Psynergy, its icon resembles a horseshoe magnet, very similar to the one used for Catch. When used in the field, glitter draws a relatively fancy-looking glowing circle around Felix, and remains surrounding Felix for about ten full seconds with visible static bolts emanating off of the circle. Although no actual uses for the spell have been discovered in game there is a rope similar to the ones Lash is used on in one of the Debug Rooms that seems to react to it. It is possible that The Lost Age was going to feature some puzzles involving using the Magnet Psynergy to influence nearby objects that would not have been influenced otherwise. It costs one Psynergy Point, is of the Venus element, can be used in Towns, and its description is ???.

Paralyze
Paralyze is a battle Psynergy hidden in the code of both games. It can be hacked into a character's Psynergy collection with a code like CBA's 82000AA8 0077, which hacks it into Felix's first slot. When checked in the overworld, the Psynergy has no icon, and its description consists of one single "?". When it is used in battle, however, a unique visual effect resembling a yellow cloud laced with crackling electricity appears at a targeted enemy's position. The enemy may be afflicted with the Stun status condition. The spell is of the Jupiter element, costs 7 PP, and has a range of 1.

Reflect
Reflect is a battle Psynergy hidden in the code of both games. It can be hacked into a character's Psynergy collection with a code like CBA's 82000AA8 0081, which hacks it into Felix's first slot. When checked in the overworld, the Psynergy has a unique icon, unlike most in-game battle effects not meant to be used as Psynergy, and its description consists of one single "?". When it is used in battle, a visual effect does occur, resembling the Wish Psynergy as it applies to one single Adept. Its battle effect is not known, however; the battle text below will display "Felix feels the effects of Reflect!" But said effects are not known; it does not appear to influence the action. It costs five Psynergy Points, is of the Mercury element, can be used in battles, and its target range is registered as one Adept.

Regenerate
Regenerate is a battle Psynergy hidden in the code of both games. It can be hacked into a character's Psynergy collection with a code like CBA's 32000BF4 0280, which hacks it into Jenna's first slot. When used in battle the visual effect resembles the Wish Psynergy as it applies to only one Adept. Its battle icon is a simple red "X", with a description of a single "?". When used in battle it will actually give you around 50 damage, and after every turn for four turns will heal you by an amount equal to 60% of your maximum HP meter - a very powerful healing effect, and the game will report "[Character] stopped recovering HP!" when the turns are over. It costs six Psynergy Points, is of the Mercury element, can be used in battles, and its target range is registered as one Adept.

Taint Psynergy series
Taint and Poison are battle Psynergy hidden in the code of both games.

When it is used in battle, a unique visual effect occurs where vaporous green gas gathers into a targeted enemy horizontally. Taint costs 4 PP and may inflict the target with Poison, while Poison costs 6PP and may inflict the target with Deadly Poison. Both spells are of the Venus element and have a range of 1.
