Sea of Stars Walkthrough: How to Beat the Toughest Bosses and Find Every Secret

Sea of Stars Walkthrough: How to Beat the Toughest Bosses and Find Every Secret

You’re standing on a floating island, the music is swelling with that Chrono Trigger energy, and you realize you have absolutely no idea where the next rainbow conch is hidden. It happens. Sea of Stars is a gorgeous love letter to the 16-bit era, but it’s surprisingly dense. Sabotage Studio didn't just make a pretty game; they made one that demands you actually pay attention to the environment.

Most people looking for a Sea of Stars walkthrough are stuck on one of two things: a specific puzzle in the Solstice Shrines or a boss that keeps wiping their party because they haven't mastered the "locks" mechanic. Let’s get one thing straight right now. This isn't a game where you can just grind levels until you’re overpowered. If you try to brute force the Fleshmancer’s minions without understanding damage types, you’re going to have a bad time.

The game follows Zale and Valere. They’re Solstice Warriors. One does sun stuff, the other does moon stuff. Simple, right? Not really. The nuance lies in how you weave their abilities together with the rest of the crew, like Garl—the best cook in RPG history—and the later party members who bring more technical utility to the table.

Getting Started: The Basics Everyone Ignores

Before we get into the weeds of the level-by-level progression, we need to talk about timing. If you aren't hitting the action button right as your attack connects, you’re leaving about 30% of your potential damage on the table. It’s not just for extra hits, either. Defensively, timing your blocks is the difference between a boss move taking out half your health or just being a minor annoyance.

Live Mana is the other thing. When you hit an enemy with a regular attack, they drop little shiny orbs. You can boost. Boosting adds your magical element to a physical attack. It’s the only way to break certain locks. I’ve seen players go through half the game forgetting they can stack up to three boosts for a massive hit. Don't be that person.


The Early Game: Mooncradle to Elder Mist

The tutorial in Mooncradle is charming but slow. Once you get out into the world, the real challenge begins. Your first major roadblock is likely the Elder Mist.

This boss is a lesson in target prioritization. He has two parts: the sword and the mist itself. If you attack the mist while the sword is up, he counters. Hard. You have to disable the sword first. Use Valere’s Moonerang—which, by the way, is the most broken move in the early game if you can keep the deflection streak going. I’ve seen people hit 20+ bounces, and it absolutely shreds the Elder Mist’s HP.

Finding the Hidden Stuff early on

You’ll see a lot of ledges you can't reach and blue crystals you can't move. Don't freak out. This is a classic "Metroidvania-lite" setup. You won't get the Graplou (the grappling hook) until later in the Moorelands. Once you get it, the game opens up.

  • The Moorelands: Look for the hidden caves behind waterfalls. There’s almost always a chest.
  • Lucent: This town is spooky, sure, but it’s also where you start the "Solstice Shrine" questline.
  • Rainbow Conches: These are the ultimate collectible. You need 60 for the true ending. Yes, 60.

Middle Game Complexity: The Sea of Night and Beyond

Once you get your ship, the Sea of Stars walkthrough really expands. You aren't on rails anymore. You can visit different islands, but the main path takes you toward the Necromancer’s lair. This is where the difficulty spikes.

The Dweller of Woe is a marathon, not a sprint. You’ll need to manage your MP carefully. This is where Garl shines. His "Nourish" ability is cheap and keeps the party's momentum going without burning through your precious food supplies. Speaking of food, always keep a stack of Hearty Stew or Braised Pasta.

Breaking the Locks

The lock system is the core of the combat. When an enemy is charging a big move, a series of icons appears above their head. You need to hit them with those specific damage types (Sun, Moon, Blunt, Sword, Poison, etc.) to weaken or cancel the move.
If you see a lock with four icons and you only have two turns, don't panic. Even breaking two of the four will reduce the damage of the incoming attack.

The Puzzle Solstice Shrines

These are optional, but not really. If you want the best gear and the hidden skills, you have to do them. Most involve manipulating light beams or moving blocks.

  1. Western Island Shrine: This one is all about the sun/moon dial. You have to move the shadows to hit the runes on the floor.
  2. Evermist Island Shrine: Requires the Graplou and some clever platforming.
  3. Jungle Path: This is where things get tricky with the day/night cycle.

Honestly, if you're stuck on a puzzle, just walk away and come back. The solution is usually simpler than you think. Sabotage Studio likes to hide things in plain sight.

End Game: The Path to the True Ending

I won’t spoil the story beats, but reaching the "final" boss isn't actually the end. To see the real conclusion of Zale and Valere's journey, you have to complete a checklist that would make a completionist sweat.

  • Finish all Solstice Shrines.
  • Find all 60 Rainbow Conches.
  • Defeat the secret boss in the Golden Pelican.
  • Free the spirits of the fallen.

It sounds like a lot. It is. But the payoff is one of the most satisfying endings in modern RPG history. The final dungeon, the Fleshmancer’s Castle, is a gauntlet. You need to be at least level 20-22 to feel comfortable here.

Why You Keep Losing to the Fleshmancer’s Minions

They have high resistance to everything except their specific weaknesses. Use Serai’s Disorient move. It pushes the enemy's turn back. It is arguably the most powerful utility move in the game. If a boss is about to wipe you, just kick them further down the timeline. It buys you breathing room to heal up or set up a combo.

Secrets and Easter Eggs

Sabotage Studio put a ton of love into the world-building. Have you talked to Teaks lately? She’s the traveling historian. Every time you find an artifact, take it to her at a campfire. She tells stories that fill in the gaps of the world's lore. It’s not just flavor text; some of it hints at the connection between Sea of Stars and their previous game, The Messenger.

The Crypt: There is a massive crypt in the game filled with names. These are the Kickstarter backers. It’s a cool place to explore, and there are some hidden items tucked away in the corners if you’re patient enough to look.

Fishing: Don't ignore the fishing minigame. Each lake has different species. Catching every type of fish gets you rewards from the master fisherman in Mirth. Plus, it’s a great way to get ingredients for high-level cooking recipes like the Surf and Turf.

Common Misconceptions

People think you need to grind. You don't. The game uses a "bounded" leveling system. If you fight most of the enemies you encounter naturally, you will be exactly the right level for the next boss. Over-leveling is actually quite difficult because the XP requirements scale aggressively.

Another mistake? Ignoring the relics. Relics are the game’s difficulty modifiers. If you’re finding the combat too hard, turn on the "Amulet of Storytelling" for more HP and auto-healing after combat. If it’s too easy, there are relics that make the timing windows tighter. It’s your experience—tailor it.

Actionable Steps for Your Playthrough

To get the most out of your run, follow this loose priority list.

  • Master the Moonerang: Seriously, go to a low-level area and practice the timing until you can hit at least 15 bounces consistently. It’s your primary boss-killer.
  • Talk to everyone in Mirth: As you find building plans, bring them to the settlers in Mirth. This town acts as your hub, providing shops, a spa for stat boosts, and a fishing pond.
  • Use Combos immediately: Don't save your combo points. They reset after every battle. Use "Solstice Strike" to recover MP or "Soonrang" for multi-target damage early and often.
  • Check behind everything: Sabotage loves hiding chests behind pillars, under bridges, and in the "foreground" where the camera perspective hides the path.

The journey from a novice Solstice Warrior to a god-tier hero is long, but it’s never unfair. This game respects your time, provided you respect its mechanics. Keep your eyes open, time your blocks, and never, ever underestimate the power of a good bowl of Garl’s soup.

If you’ve reached the Sky Island and feel underpowered, go back and finish the side quests for your party members. Each character has a specific quest in the late game that unlocks their ultimate weapon and a powerful new skill. These aren't just fluff; they make the final encounter significantly more manageable. Focus on Serai’s quest first—her ultimate weapon provides a massive boost to her delay capabilities, which is crucial for controlling the endgame's chaotic turn orders. Check the map for green exclamation points or talk to your party at the campfire; they'll usually drop hints about where they need to go to settle their pasts.

Keep an eye on the constellations in the sky as well. They aren't just there for decoration; they often point toward the location of the next Solstice Shrine or a hidden treasure island. The world of Sea of Stars is meant to be poked, prodded, and poked again until it gives up its secrets.


Next Strategic Move: Focus on collecting the first 15 Rainbow Conches as soon as you reach Lake Docarri. This will get you the "Eye of Yomara" accessory, which allows you to see enemy HP and their specific weaknesses during combat, making the lock-breaking mechanic much less of a guessing game.
