Key Sigils in Genshin Impact are needed for the ritual to open the portal to Enkanomiya. This ritual needs to be done as soon as possible because Enkanomiya starts to corrupt the land of Sangonomiya. If left to continue, the beautiful island will soon turn into a desert, and the sealed monsters within may threaten the surface.
To make this task easier, the game actually provides a marker to show where Genshin Impact players need to go. However, one of these markers is directing people to the middle of the sea, which causes plenty of confusion. Luckily, this is not a bug and is an intended feature. People who have just recently played the prerequisite quest, The Moon Bathed-Deep, would find that this place is trivial to find. But for those who have forgotten, then they can follow the following guide to look for the remaining Key Sigils in Genshin Impact.
How To Look For The Remaining Key Sigils In Genshin Impact
There are two Key Sigils that need to be found to complete this part of the quest. One is located at the "Fin", while the other is at the "Heart". Finding the one on the Fin is an easy task as it's visible to the naked eye, but the other Sigils is a tough task to find if players have forgotten The Moon Bathed-Deep World Quest in Genshin Impact.
The marker on the map gives the impression that the item exists in the water. But in truth, players can find this Key Sigil under the water; In the "Heart" of Watatsumi, to be exact. To find the entrance to this place, players have to go to the marked spot. A decent landmark is a large waterfall that can be seen directly to the right side of the cave.
Upon entering the place, players will come across three Fatui enemies. As they're considered over-world mobs, defeating them should be a simple task. Afterward, simply walk to the Key Sigil in the middle of the altar to retrieve it.
For the second Key Sigil, use the Teleport Waypoint on the island's north side. Then, travel shortly to the designated spot. The needed Genshin item can be found on a cliff between the two circular stone altars. Be aware as there'll be plenty of Ruin Machines in the area, ready to disturb the players.
After retrieving the two Key Sigils, the next step players need to do is activate two altars. Go back to Watatsumi Island and follow the direction. On the map, Travelers will find two blue spots where the altars stand. Then, use the Key Sigils to break the seal. After following the ritual, players will soon gain access to Enkanomiya, a land of ancient Watatsumi civilization.
Genshin Impact is now available on Mobile, PC, PS4, and PS5. A Switch version is in development.
