Tail of Watatsumi is part of The Moon-Bathed Deep subquest in Genshin Impact 2.1. There are multiple sub-quests in the Moon-Bathed Deep World Quests. These multiple sub-quests tell about the mythology of Watatsumi island and its people’s origins. This walkthrough demonstrates how to complete the Tail of Watatsumi to collect Spirit Pearl.
To get all the subquest you’ll need to speak with Tsuyoko, the Shrine Maiden of the Sangonomiya Shrine. First, teleport to the Statue of the Seven on Watatsumi Island and head up the hill to the West. You’ll see a ruined building and Tsuyoko standing off to the right. Speak with Tsuyoko to learn that Watatsumi Island is turning into a desert. To save the Watatsumi Island a sacred ritual needs to be done between the Sangonomiya and Enkanomiya.
The first part of this quest is to open the path to Enkanomiya, to do this you need to break the five seals on Watatsumi Island. You will automatically get four quests for the Eye, Fang, Fin, and Tail of Watatsumi after speaking with Tsuyoko. On completing these four quests you will get access to the Heart of Watatsumi sub-quest.
Tail of Watatsumi
The Tail of Watatsumi is part of ‘The Moon-Bathed Deep’ World Quest Series. As you start the subquest ‘Tail of Watatsumi’, your first goal will be to go to the southeastern island in the Watatsumi group of Island. I have marked the location of the island on the map.
Go to the “Tail”
Head to the island as marked on the map to break a seal (out of five) to enter Enkanomiya. Walk up the hill and defeat all the enemies to reach the sealed shrine. Besides the shrine, you’ll find a stone statue with the following message.
“This holy hall contains a divine blessing. Tread lightly and walk slowly, following the lights. Run not, rush never, make no hue or cry, and approach with piety in one heard for our great Omikami’s grace.”
Break the “Tail” Seal
After reading the message, walk down the hill from the shrine to find an Electrogranum tree. Pick up an Electrogranum and head back towards the shrine to ignite every stone pillar on the way up. You will find a total of six such pillars near the shrine.
Defeat the Fatui Ambushers
After each of the six pillars has been ignited the Shrine will get unlock. At the same time, a group of Fatui enemies spawns in the area.
Obtain the Spirit Pearl
Eliminate all the enemies and head back to the sealed shrine of the island to collect Spirit Pearl.
