Sea of Stars: All Treasure and Collectibles Checklist

Here is a list of all treasure chest in Sea of Stars. This is NOT a walkthrough!


NOTE: Missables!

Before you continue reading, there are 2 missables I think you should be aware of ASAP:

  • As soon as you gain the ability to fly, talk to SeraÏ  while camping to get Joce’s Belt Buckle. You can miss this if you defeat the boss in the Throne of The Queen That Was before acquiring it. I’m still investigating the exact point it becomes missable.
  • Also around the same time, but not as missable per se, you can get the Artful Gambit relic in the same boss area as the point above. If you want to reduce the bosses you have to fight in NG+ for the What a technique! achievement, then it’s good to get this relic as early as possible (as soon as you can fly). I still think it’s less of a hassle to just do all 10 bosses in NG+ though.

Some parts are spoiler-tagged because they’re points related to the middle/end of the game.
