You just finished the first game. You transferred your data. Now you’re standing on a beach in Indra, playing as Felix, and everything feels... different. It’s huge. Honestly, the scale of the Great Eastern Sea is enough to make anyone drop the GBA and go for a walk. But that’s the thing about a Golden Sun Lost Age walkthrough—it’s not just a map. It’s a massive exercise in sequence breaking, Djinn hunting, and praying you didn’t forget the Force Orb in the first game.
Most people play this game wrong. They rush to Air’s Rock, get frustrated by the sheer size of it, and quit. Or they miss the optional stuff and hit a brick wall when the final boss starts acting like a god. Let’s talk about how to actually navigate Weyard without losing your mind.
The Indra Problem and the "Open World" Trap
Early on, the game feels linear. You hit Daila, you go to Kandorean Temple, you get Lash. Simple. But once you get that boat—well, it’s not a boat yet, it’s a floating piece of wood—the world opens up in a way that’s frankly terrifying for a handheld game from 2002.
The biggest mistake? Heading straight for the plot.
If you don't take the time to explore the tiny islands scattered across the Sea of Time, you’re going to be under-leveled and under-geared. Camelot (the developers) loved hiding the best stuff in places you have zero reason to visit. For example, Yallam. You need to get there. You need the Sunshine smithing. Without it, your weapons are basically wet noodles.
Why Air’s Rock is the Great Filter
Every Golden Sun Lost Age walkthrough has to address the elephant in the room: Air’s Rock. It is objectively too big. It’s a dungeon that feels like three dungeons stapled together. You’ll spend two hours pushing pillars and blowing wind at purple statues.
Here’s the truth: You don't have to do it immediately, but if you skip it, you miss Reveal. And if you miss Reveal, the rest of the game is essentially impossible.
- Pacing yourself: Don't try to "speedrun" the Rock.
- The Psynergy Trick: Keep your party’s PP high by swapping characters in and out of the front row.
- Don't ignore the exterior: There are Djinn out there that most people walk right past because they’re too focused on getting inside.
The Data Transfer Reality Check
Did you use the Gold Code? If you didn't, your Golden Sun Lost Age walkthrough experience is going to be objectively worse. I’m serious. The Gold Code carries over your stats, your items, and most importantly, your Djinn from the first game.
If you don't have all 28 Djinn from the original Golden Sun, you cannot unlock the hardest dungeon in the game, Anemos Inner Sanctum. This isn't just some "bonus room." It’s where Iris lives. Iris is the most powerful summon in the franchise. Without the transfer, you're locked out of the true "ending" content. It sucks, but that's how they designed it back then.
Missable Djinn You’ll Regret Ignoring
Let's look at the ones people always forget.
Breath in Apojii Islands.
Ether in the Tundaria Tower.
Serac in the Islet Cave.
Seriously, the Islet Cave one is a nightmare because it requires the Turtle Li'l Frog sidequest which starts all the way back in the Sea of Time. You have to give a bird a cracker. Then a cow gets some milk. It’s a trade sequence that spans the entire globe. Most players think it's flavor text. It isn't. It's the key to a top-tier summon.
Breaking the Combat System with Class Changes
Most players keep Felix as a Squire and Jenna as a Flame User. That’s fine. It’s safe. It’s also boring.

If you want to actually dominate the late-game bosses like the Sentinel or Valukar, you need to start mixing Djinn. Put some Mercury Djinn on Felix. Suddenly, he’s a Ninja. He’s faster, he hits harder, and he has multi-target Psynergy that actually matters. The "class" system in The Lost Age is where the depth is, but the game is terrible at explaining it.
Basically, the more you diversify, the stronger your base stats become. However, there’s a trade-off. If you use your Djinn to summon, you lose those stat bonuses until the Djinn recover. It’s a risk-reward loop. Against the Doom Dragon, if you summon everything on turn one, your HP will drop by 30%, and he will wipe you out with a single Cruel Ruin.
The Lemuria Disappointment
We spent the whole first game talking about Lemuria. Babi wanted the Draught. Kraden wanted the knowledge. Then you get there and... it’s a retirement home.
The real value of Lemuria isn't the story; it's the Grindstone. This gives you the "Grind" Psynergy, which lets you enter the Western Sea. This is where the game doubles in size. You go from the "tutorial" islands to the massive continents of Hesperia and Atteka.
- Pro Tip: While in Lemuria, make sure you win the lucky medal game. The Spirit Gloves are incredibly helpful for your healers.
- The King's Prize: Talk to Hydros, but pay more attention to the map in his palace. It literally shows you where to go next.
Managing the Reunion
Midway through the game, Isaac’s party joins Felix’s party. This is the "Avengers Assemble" moment of the GBA era. You suddenly have eight characters.
Managing an eight-person party is a logistical headache. You have two front rows, essentially. Put your tanks (Felix, Isaac, Garet) in the front, and keep your utility players (Ivan, Sheba, Jenna) ready to swap in when you need a specific Psynergy or a massive heal.
Wait. Don't forget Jenna’s unique role. Because she has high Agility and decent Attack, she’s actually a better "spell-blade" than Isaac in certain setups. If you give her the right forgeable weapons from Yallam—like the Tisiphone Edge—she becomes a multi-hit monster.
The Final Stretch: Mars Lighthouse
Mars Lighthouse is the peak of the series. It’s cold, it’s brutal, and the puzzles involve manipulating literal fire in a land of ice.
The boss here, the Doom Dragon, is a three-headed nightmare. He has multiple turns per round. He can drain your PP. He can reset your Djinn to "Standby" mode, which is the most annoying mechanic in the history of RPGs.
To beat him, you need the Flash Djinn (from the first game) and the Granite Djinn. These "shield" Djinn reduce damage by 90%. You need to cycle them. Turn 1: Use Flash. Turn 2: Use Granite. Turn 3: Use Flash again. It’s the only way to survive the "Djinn Blast" attacks.
How to Handle the Post-Game
Once the credits roll, you aren't done. If you did the data transfer and collected every single Djinn (72 in total), you can head to the Anemos Inner Sanctum in Contampa.
This is where Dullahan lives.
Dullahan is harder than the final boss. He’s harder than any boss in the first game. He heals himself. He summons Charon to instant-kill your party. He uses "Formless Force" to ignore your defense.
Beating him isn't about luck. It's about "Summon Rushing." You start the battle with all your Djinn on Standby and unload everything—Iris, Daedalus, Catastrophe—on the first two turns. If he’s still standing after that, you’re probably dead. But that’s the thrill of The Lost Age. It’s a game that respects your time by giving you incredibly broken tools and then daring you to use them against even more broken enemies.
Practical Steps for Your Playthrough
- Check your Djinn count every time you enter a new town. If you're missing one, don't leave. Use a guide map specifically for Djinn locations; missing one now means 20 hours of backtracking later.
- Forge everything. Don't sell your Tear Stones or Mythril Silver. Take them to Sunshine in Yallam. Keep reloading your save until he makes the specific item you want (like the Excalibur or Xylion Armor).
- Abuse the "L" and "R" buttons. Assign Move and Mind Read to your shortcuts. You will use them thousands of times.
- Mind Read everyone. Seriously. The best lore and the hints for the hidden "Trial Road" or "Treasure Isle" are hidden in the NPCs' thoughts, not their dialogue.
- Don't ignore the status effects. Sleep and Seal actually work on many mid-game bosses. It saves you a ton of HP.
The world of Weyard is huge, and The Lost Age is a massive, sprawling epic that doesn't hold your hand. It’s okay to get lost. It’s okay to spend three hours in a forest because you can’t find a lizard. That’s the point. Just make sure that when you finally reach the top of that last lighthouse, you’ve got your Djinn ready and your best gear equipped. You’re going to need it.
