There is a relay stone puzzle in Seiraimaru of Genshin Impact 2.1 (Seirai Island). Solving the relay stone puzzle will grant you access to a Luxurious Chest. This walkthrough will show the location and solution of the underground ship relay stone puzzle in Seiraimaru (Seirai 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.]
Seiraimaru Relay Stone Puzzle
Go to the location marked on the map and through a crack in the ground jump down to reach the underground area. You’ll find a wrecked ship at the bottom of this underground area. There are 3 Discharge stones (DS), 1 Cumulation Stone (CS), and 3 Relay Stones (RS) in this puzzle. To complete the puzzle you need to connect the CS to all three DS. The discharge stones and the cumulation stone are on the underground ship and are pretty easy to spot. The 3 relay stones are scattered around in the area surrounding the underground ship. Collect these relay stones first and then head to the ship to complete the puzzle.
Location of the 3 Relay Stones
The three relay stones are present on the cliffs surrounding the wrecked ship. On one of the cliffs, you’ll see an electrogranum plant. A relay stone is hidden beneath the rubble of rocks next to the electrogranum plant. Smash the rubble to reveal the relay stone and pick it up. Then summon an electrogranum (you’ll need it to cross the energy shield).
You can easily spot 2 energy shields in the nearby cliffs. There is a relay stone under both these energy shields. Enter these energy shields and collect both the relay stones. You need to be charged with electro to cross the energy shield. Summon electrogranum (from the electrogranum plant near relay stone 1) before entering the energy shields. After collecting all the three relay stones, head to the wrecked ship and complete the circuit puzzle.
Place a relay stone between DS1 and CS to connect them. Similarly, place a relay stone between DS2 and CS. DS3 in on another half of the wrecked ship. Jump towards DS3 and place a relay stone mid-air to connect DS3 and CS. This will complete the circuit and a luxurious chest will spawn. The luxurious chest spawns in a small cave under the wrecked ship. Jump down and follow the chest marker to reach the cave and collect the luxurious chest loot.
But where is the location of the seelie? You only say that it’s used not where it is
Idk if you still need this but under the ship that has a puzzle inside of it (the one that’s kinda stuck to the wall), there a little cave, there’s a seelie inside, good day
