Suigetsu Pool Relay Stone Puzzle Solution | Watatsumi Island | Genshin Impact 2.1

There is a relay stone puzzle in Suigetsu Pool of Genshin Impact 2.1 (Watatsumi Island). Solving the relay stone puzzle will grant you access to an Exquisite Chest. This walkthrough will show the location and solution of the relay stone puzzle in Suigetsu Pool (Watatsumi Island).

A relay stone puzzle has 3 components:
DISCHARGE STONE (DS): Shoots a harmless electric current.
CUMULATION STONE (CS): Absorbs the electrical energy from Discharge Stone.
RELAY STONES (RS): Conducts the current released by Discharge Stone.
To solve the puzzle you must complete the circuit: the current from Discharge Stone must reach the Cumulation Stone. You’ll have to use the relay stones to complete the circuit. There will be multiple relay stones in the area which can be picked up and positioned anywhere. To solve the puzzle, you must position the relay stones in such a way that the current released from Discharge Stone reaches the Cumulation Stone. After the circuit is complete, an exquisite chest will appear and its loot will be yours. [NOTE: Electro-Seelie can also act as a relay stone. Your character, if affected by Electro, can also act as a relay stone.]

There are 3 Discharge stones (DS), 1 Cumulation Stone (CS), 3 Relay Stones (RS), and 1 Electro-Seelie in this puzzle. To complete the circuit you must connect the CS to all three DS. Discharge Stone 1 (DS1) is just outside the circular area (where all the pylons and Lightning Strike Probes are present). The ruins adjacent to the circular area have DS2, DS3, and CS. Discharge Stone 2 (DS2) is above the big stone gate. Discharge Stone 3 (DS3) is at the corner of the ruins. The Cumulation Stone (CS) is also at the roof of the ruins and will be easily visible. See the images below to check the location of the 3 discharge stones (DS).

1. Connect Discharge Stone 2 to Cumulation Stone (using Electro-Seelie)

STEP 1: Find the Electro-Seelie
Jump down into the circular area where the Domain gate is present. Run down the corridor (opposite the domain gate) and jump across the window at the very end of this corridor. The Electro-Seelie will be on the other side of this window. It will move away when you get near it.

STEP 2: Chase the Electro-Seelie
Keep chasing the Electro-Seelie until it reaches the roof of the ruins. The Electro-Seelie will first go upstairs and then it will move to the room above (through the broken roof). From there it will reach the roof of the ruins (through a crack in the roof). When you chase it after it reaches the roof, it will move above and will connect DS2 to CS.

2. Collect the 3 Relay Stones

2 Relay Stones are pretty easy to find. They’re in the rooms just below the cumulation stone. You’ll be in these rooms while chasing the Electro-Seelie and can pick up these relay stones then. The third relay stone is hard to get. It’s in a locked room in the basement and you need to solve the lightning probe puzzle to open the doors.
STEP 1 (Reach the 3rd Relay Stone): Jump down into the circular area where the Domain gate is present. Go down the corridor (opposite the domain gate) and turn left in the middle of the corridor to reach the area with the lightning probe. The relay stone is in the room behind the iron gate. (Note: This lightning probe is locked now).

STEP 2 (Unlock the lightning probe): Interact with the statue which is to the right of the locked iron gate. An Electro-Seelie will appear. Follow the Electro-Seelie and note the order in which it touches the 4 Pylons in this area. The first 2 pylons are in the room in front of the statue. The door to this room can be opened by interacting with the switch on its right. Hit the 4 Pylons with electrical attacks in the same order in which the Electro-Seelie touched these Pylons. This will unlock the lightning probe.

STEP 3 (Redirect the Lightning Probes): The wall behind the statue has a window. Jump through the window and get to the other side. You’ll find another lightning probe here (you need to adjust the direction of both these lightning probes to open the locked iron gate). Move ahead and open the iron door (the switch is on its left) to reach the electrogranum plant which is on the left side of the stairs. Summon an electrogranum and then correct the direction of both the lightning probes. This will open the iron gates and then you can pick up the third relay stone. Now, you have all three relay stones.

How Lightning Strike Probe Works?

The Lightning Strike Probe has a compass attached to the top that points towards players or enemies charged with electro element. On the base of the Lightning Strike Probe, there is a protruding edge representing the direction in which the compass needs to be pointed (See the picture below). Use electro element to make the compass point in the correct direction and this will make the device glow, as shown in the second picture below.

3. Connect Discharge Stone 1 to Cumulation Stone

Connect DS1 to the CS by placing 2 relay stones in between them. One of the two relay stones must be placed mid-air.

4. Connect Discharge Stone 3 to Cumulation Stone

2 relay stones are needed to connect DS3 and CS but you only have one. So, you need to charge yourself with electro and act as a relay yourself. An electrogranum plant is on the left side of DS3. Jump down and summon an electrogranum (now you can act as a relay). Place the remaining relay stone and yourself (charged with electro) in between the DS3 and CS to connect them both. An exquisite chest will appear near the cumulation stone. Collect the loot!
