There are a total of 48 trophies to unlock in Sword of the Sea, covering a bunch of activities and challenges. Here is our guide to help you unlock the Cleanse the Forbidden Valley and Forbidden Valley Shell Collector.
Check out our Sword of the Sea Review to get our full thoughts on the game.

The third zone in Sword of the Sea is a unique one. Normally, you get to maneuver around the world as the Wraith, but this time, you take control of the Great Dolphin with just a jump and the Interact buttons available to you. This zone, Forbidden Valley, is mostly a linear level with only a total of 12 Water sources and 1 Secret Shell, making it a very straightforward guide. Some of the water sources could still be missed if you aren't curious to wander, but it would be quite difficult to as the game has taught us to be adventurous during the last two chapters.
