Blubberbeast Luxurious Chest in Thalatta Submarine Canyon

A Luxurious Chest is protected by a barrier in Thalatta Submarine Canyon with multiple Blubberbeast resting around it. Solve 3 puzzles/challenges to unlock the treasure chests and unlock the ‘Do You Believe in Rapture?’ hidden achievement.

How to Unlock Luxurious Chest in Genshin Impact Salacia Plain

➥ Teleport to Thalatta Submarine Canyon southeast waypoint (near the Fishing Association NPC) and swim southeast until you see a Luxurious Chest protected by a dome. You can also see 3 thin blue lines connecting the domes and navigating you toward multiple Blubberbeast.

➥ For the first puzzle, go to the north of the Luxurious Chest to find 2 Blubberbeasts. Go further north and you will see a breakable vase. Use Blubberbeast’s ability to destroy the vase and uncover a conch inside it. Dig the conch to find a crystal, and use [Left-Click Mouse] to change the color and complete the puzzle.

➥ For the second puzzle, head to the west of the Luxurious Chest to find a Time-Trial Challenge. The challenge here is to destroy all the Pufferfruit within 3 attacks. The trick here is to stand in the middle and keep holding your E (Blubberbeast’s ability) towards the Pufferfruits and slowly move your sight to the left so the ability will hit the other Pufferfruits too.

➥ The last puzzle is on the southeast of the Luxurious Chest with another Time-Trial Challenge. This time, you need to activate all resonance points using Blubberbeast’s ability. There are no correct orders and you can just keep holding E and aiming at each Conch to activate the resonance. Once this challenge is completed (the 3rd puzzle of the Luxurious Chest), you will get the hidden achievement ‘Do You Believe in Rapture?’

➥ After all 3 puzzles are completed, the dome protecting the Luxurious Chest will disappear and you can now claim it. A current will also appear at the back of the Luxurious Chest and you can enter it to swim alongside the Blubberbeasts to another location.
