Genshin Impact Dehya Story Quest Domain walkthrough

Dehya's first Story Quest, the Mantichora Chapter: Act I - Lionblood places her at the center of conflict between two of Genshin Impact's notorious Eremite groups. Along the way, you discover bits of Dehya's past—some that she isn't proud of, and others that she will eventually come to terms with to pave a path forward.

The quest contains three segments, the third of which is called Sincerity's Facade. Within this subquest, you can enter a Domain called Bygone Glories Passed, where you can claim four Chests and solve three puzzles. Follow along to complete the Domain from start to end.

How to unlock Dehya's Story Quest in Genshin Impact – Mantichora Chapter

To unlock the Mantichora Chapter: Act I - Lionblood you must first complete the following prerequisites:

Once those are done, head to the quest menu, then click on Story Quests on the bottom left of the screen. You must spend one Story Key to unlock Dehya's Chapter.

All Chest locations & puzzle solutions in Dehya's Story Quest Domain in Genshin Impact

Below is a walkthrough of all the Chests you can get in the Domain, as well as the solutions for all of the beam puzzles. Keep in mind that it's impossible to return to Story Quest Domains after you've exited, so make sure to loot all the Chests immediately to avoid missing out on them.

Battle

Upon entering the Domain, enter the large clearing and engage in battle against the Eremites. Throughout the Domain, you'll be able to use Dehya as a trial character on the fifth slot. You need the engage against a few waves of Eremites, after which a cutscene and dialogue will trigger.

Puzzle #1

We recommend turning on the quest navigator for easier pathing. Enter the nearby room to proceed.

Inside, you need to solve a simple puzzle with two objectives. First, the color of both mechanisms must be the same. Second, the beam must be aligned between the diamonds on both mechanisms. To solve it, follow the steps below in the exact order:

• Change the beam's color so that it's yellow.
• Raise the beam once.

This will solve the puzzle and trigger a nearby room to open.

Common Chest #1

Head toward the door that just opened and follow the path to proceed. At the end of the tunnel, you'll find a locked Chest. Defeat the Primal Constructs to loot the Common Chest. Once that's done, follow the path to enter a room with another puzzle.

Puzzle #2

First, interact with the mechanism at the center. You must rotate it twice so that the purple diamond is facing the purple mechanism and the yellow diamond is facing the yellow mechanism. When correctly rotated, the mechanism will lower itself, allowing the two beams to pass through without obstacles.

Next, interact with the yellow mechanism and lower it once so that the beam is aligned with the diamond on the opposite side. Doing so will solve the puzzle and unlock the door to the next room.

Common Chest #2 + Exquisite Chest

Enter the new room and follow the path forward to encounter a locked Common Chest. Defeat the Primal Constructs to unlock the Chest and loot it before proceeding.

Once that's done, follow the path to the next room to find another locked Chest. Defeat another group of Primal Constructs to unlock an Exquisite Chest. After claiming the Chest, climb the stairs upward to find the next puzzle.

Puzzle #3

This puzzle contains two groups of mechanisms: a yellow side (left) and a purple side (right). Let's start on the yellow side on the western part of the room. Focus your attention on the mechanism in the middle. Rotate it four times so that the diamond on the second layer is connected to the vertical beam (pictured above).

Next, interact with the mechanism with the horizontal beam, where the arrow is pointing above. You must raise it twice so that the beam connects with the diamond in front of it. This will prompt the mechanism in the middle to lower, allowing the horizontal beam to connect to the purple side.

Lastly, interact with the same mechanism and change its color to purple.

Now we'll work on the purple side on the eastern part of the room. Start by interacting with the mechanism in front. You need to change its color to purple. This will cause the mechanism at the center to lower, allowing two purple beams to cross.

The last step is to interact with the same mechanism one more time. You need to change its color back to yellow so that the beam matches the color of the diamond on the opposite end. This will solve the puzzle and open the door to the next room.

Final Battle + Precious Chest

Enter the next room to prompt a cutscene and dialogue. You need to defeat a few waves of Eremites. Once that's done, loot the Precious Chest at the top of the staircase. Step on the center of the elevator to activate it and proceed with the rest of Dehya's Story Quest.
