Teyvat isn’t short of one-time Domains, which you can enter once to claim all the rewards and use as a makeshift Teleport Waypoint. In the Suigetsu Pool of Watatsumi Island, players can find one such Domain called the Palace in a Pool. One problem: it’s underwater.
Part One: Lightning Strike Probe Puzzles
Start by heading to Suigetsu Pool, which you can reach either by Waverider or by swimming from the outskirts of Sangonimiya Shrine. Head straight to the Domain marker, where you’ll find a clearing with Lightning Strike Probes (the Electro arrow puzzles) circling a pool of water.
Your goal is todrain the waterto access the Domainby solving the puzzle. It’s a little tricky, so be careful about your movement.

First,pick up an Electrogranafrom the nearby Thunder Sakura Bough. The Lightning Strike Probe will react to the Electrograna andface whatever direction it’s in.
Standingbetween the Probe and Electro Monumentwill force the arrow to face the Monument, completing one part of the puzzle. you may confirm this from thepurple glowthat will appear on the Probe (circled on the image above).
Here’s the problem:As long as you have an Electrograna on you, the Lightning Strike Probe will continue to react to it. So if you move, the Probe will move as well, breaking the puzzle.
Solve this issue by finessing your waybehind the Electro Monumenttoward the edge of the pool toblock the Lightning Strike Probe’sviewbefore moving on to the next puzzle. Alternatively, you can traverse through theThunder Sphereat the center of the pool to help you flit from one puzzle to another.
If one Thunder Sphere isn’t enough for you,interact with the nearby Watatsumi Statueto summon some more.
After completing all four Lightning Strike Probe puzzles, the Electro Monuments will unlock.Hit them with an Electro Elemental Skillto drain the water halfway through.
Part Two: Activate Mechanisms
Jump into the water, and you’ll see the roof of the Domain. Swim toward the tiny peephole in front of it and keep going straight until you see part of a tree. Climb it, and you’ll find yourself on a small clearing with a locked gate.
There arethree mechanismson the wall. Interact with them to unlock the gate. Enter the now-open door and you’ll find a stairway leading to the water.
Look above you.You’ll find a peephole in the ceiling—large enough for you to enter. Climb the wall and head to the platform above.
There, you’ll find a mechanism, which you need tointeractwith to drain the rest of the water. After, head back to the Domain and interact with it to unlock!
