Sword of the Sea, developed and published by Giant Squid, is an atmospheric adventure where you are an awoken Wraith with the task of restoring the sea. As you do so, you will encounter many collectibles, all of which contribute to its lore, the progression of the game, and ultimately the coveted platinum trophy!
These collectibles include: All water sources needed to cleanse the chapter, all secret shells, all Stele messages, whales to ride, and frogs to meet! Also, keep in mind that there are two more collectibles tied to trophies, tiles, and treasure chests; however, you only need to collect 10 of each across any playthroughs. They are numerous enough and will easily be obtained through normal play; therefore, it is not included in this collectibles guide.
