Sea of Stars True Ending and 100% Completion Guide

To unlock the true ending in Sea of Stars, you must beat the final boss, watch the initial credits, reload your cleared save file, and complete every companion side quest. After reloading, travel to the Moorlands to inspect the stone carvings, which serve as physical trackers for each unfinished companion storyline. Once all carvings are lit, activate the central mechanism to unlock the path to the true final confrontation.

Reaching full 100% completion requires additional endgame tasks: turning in all 60 Rainbow Conches, defeating every Wheels champion, clearing all 23 fishing ponds, beating the Quiz Master's trivia packs, and collecting four hidden Flimsy Hammers.

Unlocking the True Ending Sequence

The quest flags for the true ending only activate after you complete the main story once and reload your cleared game. Head to the Moorlands to check which companion objectives still need attention. You must complete five primary side quests:

• Duke Aventry and the Flooded Graveyard: Travel to the Flooded Graveyard, recover Duke Aventry's medallion, and defeat Romaya to free him from his torment.
• The Golden Pelican Feast: Collect the required recipe ingredients across your travels to secure reservations at the elite dining establishment in Brisk, bringing Garl's culinary legacy to a close.
• The Solstice Shrines and Elder Mist: Solve the puzzle trials inside every Solstice Shrine across the map, then return to the Elder Mist for an upgraded rematch.
• The Queen That Was: Assist Serai by tracking down and destroying the ancient mechanical construct located on the Lost Island of Cleave.
• The Sunken Ruins: Guide B'st through the submerged facility beneath the sea floor to unlock his full combat potential and acquire his ultimate weapon.

When all regional carvings in the Moorlands are illuminated, trigger the central device to open the portal leading directly to the true final boss.

Finding and Redeeming All 60 Rainbow Conches

Rainbow Conches are hidden across the world inside chests, breakable pots, and as rewards for local favors. Bring them to Lake Docarri and turn them in to the merchant Mirna, who gives milestone rewards at specific conch thresholds.

The most critical tool for full collection is the Falcon-eyed Parrot relic, which unlocks early in Mirna's reward path. When toggled on in the Relics menu, this parrot provides callouts whenever you view an island from the world map or sea map, telling you if any chests, Rainbow Conches, Wheels champions, or fishing ponds were missed in that sector.

Do not waste time scouring every zone on foot early in the campaign. Wait until late in the story when you unlock full flight. Once you have aerial travel and the Falcon-eyed Parrot enabled, systematically clear every island until all 60 conches are secured. Submitting the full set of 60 rewards the final crafting recipe needed to complete your gear catalog.

Defeating Every Wheels Champion

To complete the Wheels checklist, defeat the local tavern champion in every settlement across both worlds. Winning matches upgrades your wheel tier and unlocks advanced figurine pairings.

Each victory promotes your wheel from Copper to Bronze, Silver, Gold, and Diamond, adding more roll slots and upgraded dice faces. Defeating all regional players unlocks the final match against the Clockwork Watchmaker in the Clockwork Castle.

During high-tier matches, prioritize matching orange energy tiles over standard attack icons. Leveling up your active figurines quickly triggers class promotions on the board, dealing heavy unblockable damage to the opponent's Crown before defensive walls can mitigate the hits.

Conquering the Artful Gambit Challenge

While accessibility relics like the Truestrike Pendant can be used without penalty, the Artful Gambit relic is tied to a specific combat achievement that requires defeating 10 distinct boss encounters with the relic toggled on.

• Relic Penalties: Artful Gambit reduces your party's maximum health by 95% and grants enemies absolute damage immunity while they are casting spells unless you break every lock on their timer.
• Defense Mechanism: When timed blocks are performed correctly, incoming damage drops to exactly one hit point. A single mistimed block will wipe the party.
• Safe Completion: You can toggle this relic on during late-game optional fights, such as Solstice Shrine rematches and arena tiers, or carry it into a New Game Plus playthrough where early story bosses have simpler lock patterns.

Final Clean-Up Checklists

Before finishing your file, complete the three remaining discovery checklists:

1. Clear All 23 Fishing Ponds: Catch every unique fish species across all 23 fishing holes on the world map. A cleared pond displays a checked icon on your map. Once all species are logged, visit the Master Fisher in Mirth to claim your completion rewards.
2. Quiz Master Trivia: Locate the Quiz Master in the town of Lucent to play tabletop trivia rounds. Answers test your knowledge of Teaks' campsite stories, which unlock as you bring her lost artifacts. You must clear both Casual and Expert tiers across all question packs.
3. Collect the Four Flimsy Hammers: Obtain the four secret Flimsy Hammers by finishing the ultimate trivia tier, clearing all Coliseum arena ranks, beating the Clockwork Watchmaker at Wheels, and defeating the true final boss. Take these hammers to the hidden developer room behind the breakable wall in the crypts to conclude all endgame secrets.
