‘Palace in a Pool‘ is a new domain introduced in Watatsumi Island of Inazuma Region. Watatsumi Island was added to the game in Genshin Impact 2.1 update on 1st September 2021. ‘Palace in a Pool’ is on the northeast side of Watatsumi island as shown in the picture below. This article shows how to unlock the ‘Palace in a pool’ domain in a step-by-step manner.
Palace in a Pool: They say that long ago, seawater had yet to fill this pool. The moonlight was brighter back then, and it filled the pool instead. Flowing freely like quicksilver.
Step 1: Activate the 4 Lightning Strike Probes
At the top of the pool, you will find 4 sealed electro pillars. Right behind each electro pillar, you will find a Lightning strike probe. You need to activate all 4 probes to unseal the electro pillars.
To activate the probes, you have to make the compass of the probe point towards the protruding edge of the probe base. The compass points towards players or enemies charged with electro element. Summon electrogranum from the electrogranum plant in this area to charge your character with electro. Then stand in front of the protruding edge of the probe. This will make the compass point towards the protruding edge and activate the probe. The probe will start glowing and you will know that it is activated.
To complete the Lightning Strike Probe puzzle, you will need to make all four probes glow simultaneously. The electrified probe will lose the charge after some time, so you will have to be fast. Also, the electrogranum will disappear after some time. When that happens, go to the plant and summon the electrogranum again.
Step 2: Activate the Electro Pillars
Once you have activated the four Lightning Strike Probes, the electro pillars will be unsealed. Now activate all the four electro pillars by striking them with electro attacks. When all the four electro pillars are activated, the water inside the pool will lower halfway down.
Step 3: Swim down the tunnel
After the water is lowered halfway, dive down the pool and swim in the opposite direction of the domain entrance. Swim inside the submerged tunnel until you reach a tree going to the upper floor as shown in the picture below. Climb on the tree to go to the upper floor.
Step 4: Open the Door
On this floor, you will find a few slime condensates. Defeat them. The door here is locked. To unlock the door, interact with three buttons on the walls in this room as shown below.
Step 5: Turn on the Final Switch
After unlocking the door, enter the next room and climb up the wall on the right side to reach the upper floor. On this floor interact with the switch on the corner as shown below to unflood the pool and reveal the door of the domain. Now you can simply go to the domain entrance and interact with it to unlock the domain.
