Honestly, playing Camelot’s 2003 masterpiece today feels different. You’ve probably noticed that most modern RPGs hold your hand until it hurts, but back when we were all squinting at non-backlit Game Boy Advance screens, Weyard didn't care if you got lost. This Golden Sun The Lost Age walkthrough isn't just a map of where to go; it's a sanity check for when the Great Western Sea feels a little too big.
It’s huge.
Most people get stuck because they treat Felix’s journey like Isaac’s journey from the first game. It isn't. While the first game was a linear chase, The Lost Age is an open-world maritime odyssey that predates most of the "open" games we see now. If you don't have a plan, you're going to spend three hours sailing in circles near Indra.
The Early Game Grind and Why You Need Lash Immediately
Starting as Felix is a jarring shift. You’re the "villain" now, or at least that’s what the first game told you. You start at the Kandorean Temple. This place is basically a tutorial, but it’s easy to mess up. You need to get the Lash Psynergy. Without it, your progress stops dead.
The boss here, Chesterman, isn't the problem. The problem is the rope puzzles.
You’ve got to use Move to shift pillars so you can Lash your way across gaps. A lot of players forget that Psynergy in this game is a tool for the environment, not just a way to blast enemies. After you clear the temple, you head to Daila. It's a soggy, miserable town after a tidal wave, but it sets the tone. You aren't just saving the world; you’re cleaning up the mess the first party left behind.
Once you get Jenna, Sheba, and Kraden through the Dehkan Plateau, the game opens up. Sorta. You’re stuck on the continent of Indra for a bit. Don't rush to the ship. Seriously. Spend time in the caves. There are Djinn hiding everywhere.
Decoding the Golden Sun The Lost Age Walkthrough: The Ship Problem
Everyone wants the ship. The Lemurian Ship is the holy grail of the first half of the game. But getting it isn't just about finding it; it's about fixing it. You need the Black Crystal.
This sends you to the Sea of Time.
The Sea of Time is a nightmare. It’s a literal whirlpool maze. If you don't watch the movement of the water, you’ll get spat back out to the world map. Here is the secret: watch the birds. The seagulls in the Sea of Time aren't just flavor text or background art. They follow the safe currents. Follow the birds, find the volcano, beat the Star Magician (eventually, maybe not yet, he's a jerk), and get your ship.

Exploring the Eastern Sea
Once you have the ship, the game becomes a different beast. You have the Eastern Sea at your fingertips. You can go to Izumo. You can go to Champa. You can go to Alhafra.
Most people go to Alhafra first to try and fix the mast on the broken ship there. You can’t. Not yet. You need the Pound Psynergy from the Mikasalla region. It’s frustrating. You’ll spend an hour trying to Move a rock that specifically requires Pound.
- Pro Tip: Go to Izumo. Do the Serpent quest.
- Pro Tip: Use the "Sand" Psynergy to get into places you think are walled off.
- Pro Tip: Don't ignore the penguins. Seriously.
The Serpent in Izumo is the first "real" wall for many. It’s a massive boss that heals itself. You have to use the sunlight pillars around the mountain to weaken it. If you try to brute force the Serpent without the pillars, you’re going to have a bad time. Even at level 25, it can wipe your party if you’re unprepared.
The Mid-Game Slump: Finding Lemuria
Lemuria is the goal. It’s the mythical city in the center of the ocean. To get there, you need three pieces of a trident. This is where a Golden Sun The Lost Age walkthrough usually gets complicated because the game doesn't tell you where the pieces are.
One is in Tundaria (the ice place).
One is in the Ankohl Ruins.
One is in the Shrine of the Sea God.
The Ankohl Ruins are the hardest. The puzzles involve giant stone faces that spit sand. It’s very Indiana Jones. You need to use the "Reveal" Psynergy constantly. If a room looks empty, it isn't. If a wall looks solid, it might not be. Reveal is the most important button on your GBA (or your emulator/Switch).
Once you have the Trident, you can face Poseidon. He’s the gatekeeper to Lemuria. Without the Trident, he is literally invincible. You cannot damage him. Break the shield with the Trident, then hit him with everything you’ve got. Felix should be your primary physical damage dealer here, while Jenna focuses on healing and Sheba handles the elemental buffs.
Lemuria and the Truth About Weyard
When you finally reach Lemuria, the game's pace slows down. It’s a beautiful, melancholic city. Talk to everyone. This is where you learn that the world is actually dying. The "villains" from the first game—Saturos and Menardi—were actually trying to save the world by lighting the beacons.
Wait.

Yeah. Everything you did in the first game was technically making things worse. It’s a great plot twist. While in Lemuria, you get the Grind Psynergy. This lets you sink large rocks in the water, opening up the Western Sea.
The Western Sea and the Reunion
The second half of the game is basically a "Greatest Hits" tour. You finally make it to the Western Sea. This is where you eventually meet up with Isaac and his party from the first game.
This is the most important part of any Golden Sun The Lost Age walkthrough. If you transferred your data from the first game using a Gold Code (a massive, 260-character string of text that was the bane of every kid’s existence in 2003), Isaac’s party will have all their old gear and levels. If you didn't, they come with base stats.
Trust me, you wanted the Gold Code.
When the two parties join, you have eight characters. You can swap them in and out during battle. This is where the game gets "broken" in a fun way. You can create combos that the developers probably didn't fully intend.
Best Party Combinations
- The Tank Build: Felix and Isaac in the front row. Both have high HP and Defense.
- The Mage Build: Ivan and Sheba. They’re fragile, but their multi-target Psynergy clears mobs in one turn.
- The Balanced Build: Felix, Isaac, Jenna, and Mia. You have two heavy hitters and two dedicated healers. This is the "safe" way to play.
Jupiter Lighthouse: The Peak of Level Design
Jupiter Lighthouse is widely considered the best dungeon in the series. It’s also incredibly long. It uses the "Hover" Psynergy heavily. You’ll be floating over gaps, timing your jumps, and dealing with blue electrical puzzles that require precision.
The boss fight at the top—Agatio and Karst—is brutal. They are fast, and they hit hard. They use a move called "Rising Dragon" that can one-shot your weaker mages.
- Strategy: Use Djinn to summon. Specifically, summon Ulysses or Haures early to drop their stats.
- Healing: Have Mia on constant "Wish" duty.
- Felix: Keep him in his base class or a Ninja class for high speed.
Mars Lighthouse and the Final Push
The end of the game takes you to the frozen north of Prox. This is where the Mars Lighthouse sits. It’s a fire-themed dungeon in a world of ice. The puzzles here involve melting ice blocks and navigating slippery floors.
It feels final. The music changes. The stakes are clear.

The final boss, the Doom Dragon, is a three-headed beast that has three distinct phases. Each time you "kill" it, a head falls off and it gets a new set of attacks. It has a move called "Cruel Ruin" that is devastating. It hits the entire party for massive damage and can inflict status effects.
You need to cycle your parties. When your first four characters get low on HP or PP, swap the other four in. This is the only way to survive the war of attrition that is the Doom Dragon.
Why Some Players Get Frustrated
A lot of people complain that the Djinn system is too complex. It kind of is. If you set all your Djinn to "Standby" to use a big summon, your stats drop. You lose HP, Defense, and Speed. If you time it wrong, the boss will act before you and wipe your weakened party.
The trick is staggering. Never put all your Djinn on standby at once. Use one or two, summon a mid-tier spirit, and keep your stats stable.
Also, the "Points of No Return" are real. Once you enter the final stretch of Mars Lighthouse, you can't go back and finish the optional dungeons like Anemos Inner Sanctum. If you want the ultimate summon, Iris, you need to collect every single Djinn in both games before you finish Mars.
Actionable Steps for Your Playthrough
If you’re sitting down to play right now, do these three things immediately to save yourself a headache:
- Map the R-Button: In your emulator or console settings, map the R-button to "Mind Read" or "Reveal." You will use these thousands of times. It saves you from menu-diving.
- Collect Every Djinn: Don't skip them. A party at level 40 with all Djinn is twice as strong as a party at level 50 with no Djinn. The stats and class changes they provide are the core of the game’s math.
- Talk to Kraden Often: If you’re genuinely lost and don't want to look at a map, talk to Kraden. The old man actually gives decent hints about where the party should head next.
The world of Weyard is dense. It’s full of secrets like the Turtle Islet or the hidden island of Otka. Take your time. The Lost Age isn't a game you rush; it’s a world you inhabit. Whether you're playing on original hardware or a modern screen, the pixel art and the Sakuraba soundtrack still hold up as some of the best in the genre.
Go light those beacons.
To make the most of your journey through Weyard, prioritize visiting the optional Yampi Desert Cave as soon as you get the Sand Psynergy; it contains the Trainer's Whip, which allows you to start the side quest for the ultimate class items. Additionally, ensure you have saved a "Gold Level" password from the original Golden Sun if you intend to unlock the Anemos Inner Sanctum, as it is impossible to access the game's final summon without data transfer from the first title. Focus on leveling your characters to at least Level 38 before attempting the Jupiter Lighthouse to avoid the common "level wall" encountered at the Agatio and Karst boss fight.
