This article shows the location of all the Luxurious chests in Watatsumi Island of the Inazuma region. Watatsumi Island was introduced in Genshin Impact 2.1 update on 1st September 2021.
Luxurious Chest 1/4 (Sangonimiya Shrine)
There is a hidden Luxurious chest in Sangonimiya Shrine which can be revealed by following an Electro Seelie. The Electro Seelie travels a long path and you will have to solve a few Rotating Stone Cube puzzles on the way. On reaching its destination, the Electro Seelie will reveal three hidden chests – One Luxurious and Two Precious.
Electro Seelie Starting Location
You will find the Electro Seelie on the west side of Bourou Village of Watatsumi Island at the location as shown in the picture below. At the edge of the mountain, you will find an Electro Seelie. Go near it and it will go down. Jump down the cliff and find the Electro Seelie under a tree. Keep following the Electro Seelie and after some time it will go inside a Thunder barrier and you will have to solve a Rotating Stone Cube Puzzle here.
First Thunder barrier (Three Rotating Cubes Puzzle)
The Electro Seelie will lead you to a Thunder barrier. Near the barrier, you will find three rotating cubes. To go inside the thunder barrier you will need to solve the rotating cube puzzle. This puzzle is very simple. There are three cubes (See the second picture below). Hit each cube until it faces north. You can do it by hitting the middle cube two times and the other two, three times. On solving the puzzle, the Electrogranum plant near the middle cube will be activated. Summon Electrogranum and use it to go inside the Thunder Barrier and switch it off. Start following the Electro Seelie again.
Second Thunder Barrier
Follow the Electro Seelie and it will go inside a Thunder Barrier at the north portion of Sangonimiya Shrine. Near the barrier, you will find a statue. Pay respect to the statue and an enemy will appear. Defeat it and the barrier will disappear. Now start following the Electro Seelie again.
Third Thunder Barrier
Follow the Electro Seelie and it will go inside a Thunder Barrier at the northeast portion of Sangonimiya Shrine. Climb the mountain behind the barrier. At top of the mountain, you will find an Electrogranum Plant. Summon Electrogranum and use it to go inside the barrier and switch it off. Now start following the Electro Seelie again.
Fourth Thunder barrier (Five Cubes Puzzle)
Follow the Electro Seelie and it will go inside a Thunder Barrier at the east portion of Sangonimiya Shrine as shown in the picture below. Near the barrier, you will find five rotating cubes. To go inside the thunder barrier you will need to solve the rotating cube puzzle.
In this puzzle, there are five cubes. Hitting cube 1 rotates cubes 1 & 2. Hitting cube 4 rotates cubes 3 & 4. Hitting cube 3 rotates cubes 2, 3 & 4. Hitting cube 2 rotates cubes 1, 2 & 3. To solve the puzzle you need to make all the cubes face towards the front side. Solving the puzzle gives you an exquisite chest.
Reset the puzzle and then follow the following steps to solve the puzzle:
1) Hit cube 1 three times
2) Hit cube 2 one time
3) Hit cube 3 three times
4) Hit cube 4 two times
On solving the puzzle, the Electrogranum plant near the cubes will be activated. Summon Electrogranum and use it to go inside the Thunder Barrier and switch it off. Start following the Electro Seelie again.
Hidden Luxurious Chest
Start following the Electro Seelie from the previous thunder location. Keep your eye on the Electro Seelie as it will start moving very fast from this point. Keep following it and shortly it will reach its destination as shown in the picture below. This will reveal a luxurious chest and two precious chests.
Luxurious Chest 2/4 ( Suigetsu Pool)
There is one Luxurious Chest near the ‘Palace in a Pool‘ domain in Suigetsu Pool. Suigetsu Pool is on the northeast side of Watatsumi island as shown in the picture below. To get the luxurious chest you will first need to drain out water from the pool. Click here to see how to drain out water from the pool.
After the water is cleared, go back to the top of the pool and 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 as shown below.
In this room jump through the windows on the right wall as shown below.
In the next room, you will find a closed gate at the end, interact with the lever on its left to open the gate. Go through the gate to the next room.
In this room, you will find an Electrogranum plant.
Summon Electrogranum from the plant and go back to the previous room. In this room, climb on the wall on the right side and use Electrogranum to pass through the thunder barrier.
After crossing the thunder barrier, see up and you will see an Electroculus at the top, near the ceiling. Climb the wall upto the Electroculus level. Here you will see a Luxurious chest on a small platform. Jump to reach the platform and get the chest.
Luxurious Chest 3/4 ( Mouun Shrine)
Mouun Shrine is at the western edge of Watatsumi island of Inazuma Region. On the north side of Mouun Shrine, you will find a Rotating Cube Puzzle and on the south side, you will find a Lightning Strike Probe Puzzle. Solving both the puzzles gets you a Luxurious chest.
Mouun Shrine Rotating Cube Puzzle
There are four rotating cubes on the north side of Mouun Shrine. I have numbered the cubes as shown below for easy understanding. You have to make all the cubes face inwards (make cube 1 face 3 and cube 2 face 4) to solve the puzzle. You can do so by hitting cube 1 twice, cube 2 thrice, and cube 3 once. On solving the puzzle, the Electro Seelie at the center of the cubes will start moving. Chase the Electro Seelie to its home to complete this part.
Mouun Shrine Lightning Strike Probe Puzzle
There are three Lightning Strike Probes on the south side of Mouun Shrine. All three probes are sealed. North of the probes you will see a statue with an immovable Electro Seelie above it. Pay respect to the statue to unseal the Lightning Strike Probes.
To solve the Lightning Strike Probe Puzzle you need to activate all three probes. A Lightning Strike probe can be activated by aligning the arrow at its top to the protruding edge of its base. The arrow points towards a charged object. There are two moving Electro Seelies near the probes. Electro Seelie will keep changing position from one probe to another. Get charged from the Electro Seelie and stand in front of one of the three probe’s protruding edge to activate it. Other two will be activated when Electro Seelies change position and get in front of them. When all the three probes are activated simultaneously, the puzzle will be solved and the Electro Seelie above the statue will start moving. Chase the Electro Seelie to its home to complete this part.
Mouun Shrine Luxurious Chest
After solving both the above-mentioned puzzles, when you have chased the two Electro Seelies to their home, a hidden Luxurious chest will appear.
Luxurious Chest 4/4 (Shrine of the Depths)
You will get a luxurious chest inside the Shrines of Depths at the location northeast of Sangonomiya Shrine as shown in the picture below. Check the link to know how to get the key for the shrine.
