On the Amakumo Peak in the Seirai Island, some players are stuck in a puzzle that will reward them with a ton of in-game items and an achievement upon solving it. If you are one of them, here's how you can solve the Amakumo Peak puzzle to claim your rewards.
How to solve Amakumo Peak puzzle in Genshin Impact
Players will first have to navigate to the Amakumo Peak on Seirai Island, as shown in the image above, to find the puzzle.
After you reach the first puzzle's location, you will find pressure plates that glow when you step upon them. Now, activate the pressure plates indicated in the image below.
You can deactivate the ones that are already activated by stepping on them again. After you activate the required plates, all the plates will glow, and a chest will appear at the middle one.
The second puzzle is under the lake water, and to remove it, you will have to activate the mechanism near the first puzzle. After the water is drained, a new underground location will get uncovered.
You will need to kill ruin sentinels around the basement, and they can glide in it to eliminate two more ruin sentinels. After you do it, the seals around chests will be broken, and you can open them to collect your rewards.
Activate the mechanism near chests to further lower down the water levels. Then, you need to glide down near the red door and touch the Seelie. After that, you will have to interact with the mechanism on the right side of the door to unlock it.
Enter the gate, touch the Seelie once again and open the yellow door to your left by interacting with its mechanism. Beat the enemies and interact with the red mechanism inside the room. Come out of the room and again interact with the yellow mechanism.
Now, follow the Seelie to the first floor to find a chest full of rewards, and after that, follow the other Seelie you will find in front of you. Then climb up the stairs at the right side of the red door, go through both doors, and activate the red mechanism.
Now, go back down to activate the yellow mechanism and follow the Seelie to obtain a new chest. Then, follow the next Seelie to the blue gate and to unlock it, go to its right side, turn left from the ruin sentinel, and climb the stairs.
There you will find a red mechanism; interact with it to activate and go back down. Now, pass through the red gate and activate the blue mechanism.
Then, go back to the upper platform through the stairs, go to the room on the left side of the stairs, and activate the yellow mechanism. Now, the blue door that was locked is open, and you can follow the Seelie to unlock a luxurious chest and Great Amakuma Peak achievement.
Then, you can activate the mechanism next to the luxurious chest to lower the water level even more and follow the Seelie to find more chests at the bottom full of rewards.
