Updated on September 30, 2025, by Nahda Nabiilah: The Taishan Mansion is one of the many locked domains that is protected behind a puzzle in Genshin Impact. Travelers who wish to challenge the enemies inside and earn the available rewards need to figure out how to solve the water puzzle around the domain first. You will immediately find something is wrong as the Taishan Mansion is submerged underwater.
How To Solve The Jueyun Karst Water Puzzle In Genshin Impact
Jueyun Karst is a lake located north and a little east of Tianqiu Valley. The lake is rather large, so it might take a while to figure out the puzzle that allows players to drain the water and get into the mansion. But there are two pillars located around the lake, and once the players interact with both, the Mansion will open its hidden door.
Jueyun Karst Water Puzzle Pillar #1
First head to the northeastern-most part of the lake, and there will be a pillar there. Defeat the three rounds of enemies, making sure to use the proper Genshin Impact elemental counters to get rid of them quickly. Once all the enemies are dead, grab the treasure chest before jumping up onto the pillar and interacting with the glowing, orange button on top of it. A cutscene will play showing the lake being drained of about half of its water, and that will reveal the second pillar.
Jueyun Karst Water Puzzle Pillar #2
The cutscene will show a pillar in the newly-drained lake that is encircled with glowing, orange runes and a rock on it. Around it are several tiny pagoda-looking statues. Each one needs to be filled with an orange, shining rock. These luminous rocks can be found scattered around the lake; they look a bit like giant black flowers with glowing, orange bits inside of them. Travelers just need to attack the rocks until they break
After the rock is in their inventory, return to the statue and it will activate automatically. Find three rocks, then activate all three statues. Then interact with the pillar in the center of the circle to trigger another cutscene and complete the puzzle in Genshin Impact. Don’t forget to grab the treasure chests.
How To Unlock The Taishan Mansion Domain In Genshin Impact
Once the lake is completely drained of water, the cutscene will focus in on the door of the Taishan Mansion Domain, which is now glowing and accessible. There is a precious treasure chest in front of it, so grab that and continue to the doorway. Interact with the door, and it will open, giving players access to the four levels of the Taishan Mansion. Make sure to have a great, top-tier team of Genshin Impact characters to delve into the depths of this dungeon.
