Our guide for the Genshin Impact quest titled Treacherous Light of the Depths.
Genshin Impact has had some new fun quests added to it, thanks to the latest 4.1 update for the game. In this guide we are going to cover how to clear these quests exactly!
Update: We have made minor updates to the guide on October 14, 2023.
Treacherous Light Of The Depths How To Unlock
This quest can be kind of difficult to find if you don't know where to look. There is an underground passage that can be found on the east side of the Statue of Seven located in the Mary-Ann Memorial Park. Heading from the Statue of Seven East to where we marked on the map above.
- If you're looking to upgrade your gaming experience in Genshin Impact and other games, we recommend using a Razer Kishi mobile game controller .
Once in the location, you will want to dive down under the water and get the attack powerup from the Xenochromatic Jellyfish there, which will let you attack the wooden debris covering the large hole.
After the hole is uncovered, you should head down and swim your way to the location of this mysterious cave which is underwater but also not underwater at all!
At the end of this long path will be a door, once you activate the door the Treacherous Light Of The Depths quest will then activate.
Your task is to activate some devices and also collect some components.
Collect The Light Path Component 1
The first component is directly on the left side of the entrance. Fly over to the island in the middle of the cave, and then you can walk to the left, where there are a handful of Meka enemies that you will need to defeat.
Once they are defeated make your way to the Experimental Crystal Light Path Components which is located inside of the locked ruin. Using the device you will change your perspective and will be able to move energy around within the cave.
Viola, you're there! Now there is a red canister (empty) and a blue canister (full), point the camera to the blue canister and absorb the energy then transfer it to the red one.
This will unlock the gate to where the Experimental Crystal Light Path Component is, and you can make your way through the opened gate.
Collect The Light Path Component 2
Exit the locked ruin you just went to and put the Light Path Component in the machine. Once you do this, the machine will have some lights pop out, and at first, they are all blurry, and then they come into focus.
Once that happens activate the machine again to calibrate it, the machine's light will then point you towards your second component.
Once you're there look through the device and you will see that the Component is actually right over the wall in front of you.
Climb the wall, grab the Component, and make your way back to the Device. Once inserted, just repeat what you did the last time.
Start The Optical Device
Now, we need to make our way back to the middle of the cavern. Once you're there you just need to activate the Optical Device; when this happens the lights will bounce around the room and open up a door on the lower part of the cavern.
Fly down to the bottom and make your way towards where the door opened. There are going to be two Meka there to fight, so dispatch them quickly and keep adventuring forward where there are, surprise, more Meka to fight.
Activating The Energy Transfer Terminal
Once you've made your way through the caves and opened the door to the room where two Meka are standing guard in the middle, you're almost done!
The Meka won't try and fight you just yet. The device that you need to activate needs an item to turn it on.
Simply walk north to the wall where there's a pile of rubble, destroy it grab the item then put it into the device.
Once the device is activated, the Meka will come to life. You've done this already, so dispatch them with ease.
Get The Punched Tapes For Sevigne
Now you will need to grab punched tapes for Sevigne, this part is rather easy. Just look around the area for the bright glowing spots on the ground.
Once you have all three, go back and talk to Sevigne. Once you do this, you will have access to the last part of the quest.
Dive Into The Water And Complete The Quest
Finally, dive into the water under the painting. At the end of the water current, there will be something called the Mysterious Ore, pick it up! Now, make your way back to the Fontaine Research Institute. Once at the Institute, talk to Chisseray and finish the quest.
