Seiraimaru Ship is on the western edge of Seirai Island as shown in the picture below. Seirai Island was introduced in Genshin Impact 2.1 update on 1st September 2021. On Seiraimaru Ship you will find many puzzles. This article shows how to solve all the puzzles in Seiraimaru Ship.
Puzzle 1: Exquisite Chest (Rotating Helm Puzzle)
On the Ship’s Deck, you will find a sealed Exquisite chest with four rotating helms around it. Each helm will have two arrows pointing out as shown with yellow circles in the below picture. This puzzle is very easy. Rotate all the four helms in such a way that the arrows are facing each other (See the second picture below). Solving the puzzle not only unseals the chest but also breaks a wall of the ship, creatinge a way to go inside.
Puzzle 2: Rust Worn Key
The ship’s wall that broke is on the eastern side. Above it, you will find an electrogranum plant as shown in the picture below. Summon electrogranum and jump down to go inside the ship. Go to the eastern end of the ship. Go inside the thunder barrier and disable the barrier. There you will find a common chest with a Rust worn key. Go to the opposite end of the ship (The western side of the ship), and climb to the upper floor. Use the Rust worn key to open the room. Inside the room, you will find another rotating helm puzzle. Rotate the helm to make the arrows face each other. This will unlock the exquisite chest there.
Puzzle 3: Exquisite Chest (Floor Tile Puzzle)
On the floor of the ship, you will find a set of tiles that glows when you step on them. Step on the six tiles in the sequence as shown in the picture below to unseal the exquisite chest. Solving the puzzle not only unseals the chest but also creates a hole on the ship floor, creating a way to the bottom level.
Puzzle 4: Luxurious Chest (Intact Key)
Go to the bottom level of the ship from the newly created path. Here you will find more glowing tiles on the floor. You will also see a locked door that requires an Intact Key to open. You will find a small hole on the floor with a common chest inside it as shown in the picture below. This common chest contains the Intact key. Use the key to open the door on the western end of the ship. Inside this newly opened room, you will find a sealed Luxurious chest with four rotating helms around it. Rotate the helms to make the arrows face each other. This will unlock the luxurious chest.
Puzzle 5: Exquisite Chest (Floor Tile Puzzle)
On the bottommost floor of the ship, you will find a set of tiles that glows when you step on them. Step on the eight tiles in the sequence as shown in the picture below to unseal the exquisite chest. Solving the puzzle not only unseals the chest but also breaks the eastern wall of the ship leading to a Relay Stone Puzzle.
Puzzle 6: Relay Stone Puzzle (Luxurious Chest)
How Relay Stone Puzzles Work?
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 Ship Relay Stone Puzzle
Go through the broken wall as explained in the previous section, 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.
