Luxurious Chest 1/2
This chest is located behind the first door you enter during The Ancient Azure Stars story quest as shown in the picture below.
In case visiting the first time: Enter the first door and solve the Astral puzzle to summon the chest in order to open the door up the stairs to the back of the room to gain access to the next area.
Go up the stairs and enter the room on the rear to reach a new area if you have already solved the Astral puzzle and obtained the chest.
Proceed ahead until you reach an area with translucent bridges. Cross the translucent bridges to reach the next area. In the new area, you will have to solve another Astral puzzle. Input the three correct patterns that appear on the wall in order for the wall constellation to change to an arrow pattern.
Puzzle 1
Puzzle 2
Puzzle 3
On solving the three puzzles, stars will form an arrow. Go to the wall the arrow is pointing at and touch it to reveal the next area.
Enter inside, then take the astral path up to a room with four circular switches on the floor. You will see a pattern drawn on the floor near the switches. To solve the puzzle, you need to step on the switches to form the same pattern in the sky. This can be done in 8 steps as shown in the picture below. I have named the switches as A, B, C, and D for ease of explanation.
Step 1: Step on Switch A
Step 2: Step on Switch B
Step 3: Step on Switch C
Step 4: Step on Switch C
Step 5: Step on Switch C
Step 6: Step on Switch D
Step 7: Step on Switch D
Step 8: Step on Switch B
On solving the puzzle, the precious chest in this room will unlock. Open the chest and a Star will come out from it. Follow the star until you fall into Starry Realm. Complete the Challenge of the Starry Sky there. Then take the portal back and you will find the Luxurious chest in front of the pool in the Mona Domain.
Luxurious Chest 2/2
This chest will be available only after you have completed The Ancient Azure Stars story quest. After completing the quest, jump inside the pool and enter the portal. Touch the strange ornament to reach a mirage.
You will see four switches here and some patterns in the sky. Your objective here is to make the patterns in the sky disappear. To do so, step on the switches in the sequence shown below. After that enter the portal and you will find the Luxurious chest in front of the pool in the Mona Domain.
