While you’re out and about exploring Watatsumi Island, you’ll probably come across a cave with a barrier. In order to open it, we’ll need to complete a world quest that starts in Mouun Shrine. Here’s our Genshin Impact guide to help you with the Moon-Bathed Deep world quest on Watatsumi Island.
Genshin Impact: Moon-Bathed Deep guide – The Watatsumi Island world quest
As mentioned above, all you need to do is head to Mouun Shrine (which is directly west of Sangonomiya Shrine). There, you’ll find a shrine maiden named Tsuyoko. She’ll talk to you about a mysterious place known as Enkanomiya. We won’t even be able to go there yet. At the very least, we can complete the Moon-Bathed Deep world quest in Genshin Impact.
Tsuyoko gives you several objectives. You’ll need to go to four locations on Watatsumi Island (don’t worry because you can mark them on your map). There, you’ll have to complete some mini-puzzles to obtain Spirit Pearls. You can refer to the pages below for the parts that you need help with:
After obtaining all four Spirit Pearls, you’ll unlock a secret cavern. There’s another puzzle there called the Heart of Watatsumi which we discuss in a separate guide.
