Sea of Stars Rainbow Conch Guide | All Locations and Uses

Last Update: September 1, 2023 9:30 AM


Talking to Mirna, the Rainbow Conch trader

Our Sea of Stars Rainbow Conch Guide will show you where to find each of these collectables, along with what they are used for.

Rainbow Conches are a collectable found in unique chests (blue with a shell on the front) or via short sidequests. While they don't offer any direct benefits on their own, they do have a purpose once you make your way further through the game.

What are Rainbow Conches Used For in Sea of Stars

Rainbow Conches can be traded into Mirna, a small fishman residing in the village at Lake Docarria. This area is found midway through Sea of Stars, and can be revisited freely. Mirna will give you rewards based on the total number of Rainbow Conches you have found, though they'll always remain in the key items section of the inventory to help you keep track.

How many Rainbow Conches Are There?

There are 60 Rainbow Conches in Sea of Stars, spread across every area of the game. None are missable, and they can still be collected even if you defeat the final boss.

All Sea of Stars Rainbow Conch Rewards

  • 4 - Inn Plans
  • 11 - Cornucopia accessory
  • 19 - Shop Plans
  • 22 - Fishing Hut Plans
  • 27 - Falcon-eyed Parrot Relic
  • 35 - Poutine cooking recipe
  • 39 - Spa Plans
  • 47 - Pudding Chomeur cooking recipe
  • 60 - Rainbow Star

The plans are all used to create buildings in Mirth, an area made available before reaching Lake Docarria. The Falcon-eyed Parrot Relic is another useful reward, telling you if you've missed any conches, treasure, or other collectables when selecting an area on the map.

After handing in all 60 Rainbow Conches, you'll get the Rainbow Star. The Rainbow Star is one of the requirements that must be met to unlock the True Ending of Sea of Stars.
