Insidious light from the depths in Fontaine. In it you will have to explore the ruins, repair several optical devices, and also help the researchers.
In this article we will tell you how to start Insidious Light from the Depths and launch an optical device. Read on to solve the calibration puzzle and find the experimental component of the crystalline light channel.
How to start the quest Insidious Light from the Depths
Travel to the teleporter located by the small pond east of xenochrome jellyfish, from whom you need to take the skill.
After this, swim a little further towards the shore, where you will see a gap covered with a stone. Use the jellyfish's ability to blow it up.
Next, go lower into the crevice, picking up along the way hydrocool. The water runs out at the bottom. Walk forward through the cave until you come across a door locked with a mechanism. Interact with the device to open it.
Behind the door is a huge underground space, which Paimon will comment on. The task will be added to the journal automatically after her words.
Walkthrough of the quest Insidious light from the depths in Genshin Impact
In the center of the cave, Paimon notices an unusual device and suggests finding out what it is.
Explore inside the ruins
Start exploring the cave. A bright beam leads from the dome to the ruins on the right side, follow the point where it points. Climb the structure and approach the mechanism to examine it.
Start the optical device
The device is a focusing mirror. In order to start it, it is necessary to calibrate the condensation prism.
Press "Turn on". An image will appear next to the mechanism, which becomes brighter and dimmer. Click on the button "Calibration" at the moment when the picture is the brightest and clearest - this can be noticed when the picture begins to shimmer slightly.
If everything is done correctly, the beam will point to another focusing mirror.
Investigate the other optical devices in the ruins
Go to the other side of the cave. Before solving the puzzle, win meksso that they do not interfere with the research.
This device is missing one part. We need to find the Experimental component of the crystalline light channel. The item you are looking for is located inside the nearby ruins, but the entrance to them is closed by a grate.
To open the grate, activate the terminal. Switch the viewfinder to the one on the opposite wall.
Next, take the energy from the storage tank near the cage with the fairy and transfer it to the storage tank near the entrance. The grate will open.
In a special guide they said, how to release a fairy from a cage in an abandoned laboratory.
Go inside and take the part, after defeating the mek. Install it into the device and calibrate. This time two images appear next to it - press the button at the moment when they are clearest. It will take two clicks, one per projection.
Follow the beam further to the next optical device. It is also missing a detail. Interact with the terminal to find it.
Point one of the viewfinders at the second one, located at the top of the destroyed wall near the rock. Through the second of them, it becomes clear that the required part lies on the stone platform above. Climb up there and take it.
Insert the light channel component into the focusing mirror. Now we need to calibrate the three images. As before, press the button at the moment when the picture becomes bright.
Start the optical device at the center of the ruins
When all three devices are activated, return to the center of the ruins and activate the central mechanism.
He will open a grate in the rock below him, from which several meks will emerge. Defeat them.
Continue exploring
In the center of the cave there is a descent down. Jump there to advance further.
The age ahead is closed. To unlock the device, defeat the Mek.
Investigate the mysterious room
Behind the door is a large room with two inactive mechs in the middle. Behind them you can also see a non-functional terminal.
Go to the very end of the room, where there is a pile of breakable stones. Break them to reveal a portable energy storage device.
Take it and move it to the inactive terminal. Next, click the “Run Test” button. This action will make the Meks aggressive, be prepared for a fight.
Talk to the researcher
As soon as you defeat the Meks, a researcher will come to the noise. She will be very surprised that someone broke into the old laboratory, because it was well protected. Talk to the girl to learn that the meks are prototypes that are standing here, waiting for the one who created them.
The girl's name is Sevigne. She came here to pick up the punched tapes, but now she is forced to repair the meks, so she asks the Traveler for help.
Recover the Punched Tapes
Collect three punched paper tapes inside the room:
- The first is located near the portrait.
- The second is near a cabinet with a bunch of scattered books.
- The third lies inside the room, which was located next to a pile of stones and was closed.
After you have collected all the items, return to Sevigne. She will ask you to take the punched tapes to Kisseri, and will also open the previously closed path back through the water streams.
Dive into water to exit the room
Jump into the water through the hole in the floor and enter the stream.
Swim forward through the flooded cave until you emerge. Don't forget to pick up a piece along the way mysterious ore.
Head to the new Research Institute
As soon as you swim out of the pond, move to the new Research Institute, where you need to find Kisseri.
Find Kisseri and tell the news
The girl is sitting in the western part of the institute at a table with Damestier and Villemo. Talk to her and give her the punched tapes to complete the task.
