How To Unlock Palace In A Pool Genshin Impact

The first step to unlock the Palace In A Pool domain is solving the water-level puzzle. Firstly, you need to get to the pool and observe it. Then, follow these steps to solve the puzzle.
  • Summon Electroganum from nearby Thunder Sakura Boughs and move to make the arrow rotate and point to the correct direction. Or else, you can use Beidou's elemental skill to get Electro-inflicted.
  • Light up all the Electro Monuments rapidly to clear the puzzle. It's recommended to use the elemental skills or charged arrows of Lisa, Sara, or Fischl.
Use Sara's charged arrows to light up all the Electro Monuments.
  • Drop to the water and enter the Hallways on the wall of the well that faces the Domain's entrance. Swim through the tunnel and enter the inner room. As the tunnel is pretty long, make sure you have full stamina before start swimming.
  • Press three buttons on three walls of the inner room to open the metal gate.
  • Go through the gate and look up to the ceiling and you will find a Relay Stone. Climb to the wall and glide toward the Relay Stone. Then, you activate the Cube mechanism to remove water in the hole.

After draining all the water in the hole, you can interact with the entrance of the domain to unlock it.

How To Solve Relay Stone Puzzle

When you press three buttons on the wall to open the metal gate, there is a downward stair that you haven't explored yet.

  • Follow the Electro Seelie to find and activate Electro Monuments in the right order and unseal the Lightning Probe.

  • Climb up the ceiling and collect two other Relay Stones.
  • Place Relay Stones between Recharged Stones and the Cumulative Stone.
