Dune-Entombed Fecundity: Part 3 is a quest under The Dirge of Bilqis in Genshin Impact’s 3.4 update.
Your objective is to complete the final part of the journey to the Eternal Oasis.
Here’s a walkthrough and guide of Dune-Entombed Fecundity Part 3 in Genshin Impact.
To begin the quest, return to the surface as marked on the map.
Drive the ancient machine
You will be teleported back to the control cabin in the ancient machine.
Activate the machine.
Point the machine towards the left side. Just click on it.
Use the arm
For the next part, just click on the marked area on the screen to use the arm and create a path.
After the dialogue, you’ll discover that Azariq is one of the traitors.
Defeat Azariq and his subordinates.
After exiting the place, confront Aderfi who is with the Fatui.
Defeat Aderfi and the Fatui
You’ll then need to defeat Aderfi and some Fatui members.
Check the item that dropped. You’ll find a letter between Azariq and Aderfi.
Return to the machine’s interior
Now that the machine has fallen, it created a new hole on the ground. Enter the machine’s interior via the arm again.
Enter the tunnel
Once you’re inside the machine, look for the marker and head to it. You’ll reach a tunnel.
At the end of the tunnel, descend and you’ll see another tunnel below. Use it.
Remove the sand
Keep going until you see a mechanism. Activate it to remove the sand.
Proceed deeper inside. On the way there, you’ll see a Dendroculus in a small cave. There’s also a blue orb device.
Release the blue orb but this one’s optional.
The blue orb will lead you to a room. Defeat the Primal Constructs and get the treasure after the orb enters the pillar.
Open the ancient gate
Back to the main objective, head to the end and you’ll see an ancient gate above. Defeat the Primal Construct and open the door.
Inside, you’ll see a chest.
To open the ancient gate, you need to solve some puzzles.
In one of the rooms, you’ll see a mechanism. Activate it.
On the way out, release the blue orb but it’s probably optional.
Back at the central area, start the next mechanism.
The path downwards will be open. You can release the blue orb again and go down.
Here, you’ll find more puzzles.
Rotate the two cells to face the middle one and it will give you a chest.
Then, rotate the cell near the blue barrier so that it faces the cell behind the barrier.
It will remove the barrier.
Activate the mechanism inside.
Head to the next mechanism that is marked and start it also.
Follow the path and you’ll see a Primal Construct. Defeat it to unlock the console.
Use the console to remove the barrier.
Before you leave, release the blue orb again.
Bring the orb to the pillar and you should get a chest.
Now, start the mechanism.
Go back to the central area and you can start the mechanism that is unlocked. The ancient gate will open.
Follow the path and defeat the snakes along the way.
Obtain Liloupar’s fragment
Get Liloupar’s fragment where the Dendroculus is.
Head into the depths
Now, head into the depths. Defeat the Primal Construct along the way.
Activate the ancient mechanism
Use the ancient mechanism.
Then, go to the bottom and activate the yellow mechanism.
Defeat the attracted monsters
Now, defeat five monsters. You’ll have to do so before they destroy the yellow mechanism.
After the fight, you’ll meet Ferigees, Liloupar’s sister who is constrained to the tomb for a thousand years.
You’ll then need to defeat Ferigees. The fight is quite straightforward.
You can’t attack her until you defeat the Primal Constructs first.
The barrier will go down and you’ll have a small amount of time to attack Ferigees.
The barrier will go up again and she’ll spawn more enemies. Repeat the process until she’s defeated.
