Genshin Impacts The Chasm has a long world quest line called The Chasm Delvers. Completing the first three parts of The Chasm Delvers is required to progress through the new Archon Quest that we covered in the Archon Quest – Requiem of The Echoing Depths guide. This guide covers the last two parts of The Chasm Delvers: Perils in The Dark and Whyfore Did the Spiritstone Descend. The two quests contain puzzles and a fight with a variation of the newest boss, the Ruin Serpent.
The Chasm Delvers: Dangers in the Dark
Drop near the mud and cleanse it with your Lumenstone Adjuvant. The revealed journal of Fatuus instructs you to activate two bells in the northern and southern ruins.
ruins in the north
- This bell is easy to “unlock” so to speak. Climb to the top of the structure shown on your map. You will then see four monuments covered in the black goo and the bell between two torches. Clean each monument with your adjuvant and defeat the enemies that appear here. After all four monuments have been unlocked, they will be locked again. A Shadowy Husk will appear. Kill him and then the bell can ring freely. Hit the bell with your gun to make it “ring”.
ruins in the south:
- Climb up to the ruin marked on your map until you come across a level with two Seelies. You have to solve the puzzle here with the Seelies before you can ring the bell. When you touch the seelies, they move a certain distance. Notice that one seelie moves clockwise and the other moves counter-clockwise.
- To solve the puzzle, you need to light up all the totems at once. First, remove goo from all totems. They can now be lit by the Seelies or your Lumenstone Adjuvant. So you have to touch the seelies one by one and make them stop at two separate totems. Park yourself at the third. Since the fourth totem will automatically light up (charge the nearby totem to light it up) – this will solve the puzzle.
Climb to the top of the ruin and you will see a new floating sealie. Interacting with the Seelie will open the gate below. Drop, get rid of the goosebumps and fight the Ruin Grader. When you’re done, climb back to the ruins and press the bell.
After you’re done, you’ll meet an Electro and Pyro Abyss lecturer named Agnarr and Egill. If you have Cryo and Hydro on your team, you can kill the two Lectors faster. After defeating them, pick up the dropped Curious Cube.
Why did the Spiritstone descend?
Head down the path and reach the Stone Halls area. Charge the five pink stones with the Lumenstone Adjuvant. Each of the pink bricks is covered in purple slime, and you’ll have to fight two to three enemies in each location. The stones require you to stand near them in order to charge them. There are many “Charging Stations” scattered near the pink stones if you run out of Lumenstone Adjuvant Juice.
After the four pink stones are recharged, the arena under the crystal will be populated by a variation of the Ruin Serpent – the new normal boss in The Chasm. Please read our separate Ruin Serpent guide on how to beat the boss.
This completes The Chasm Delvers quest line. Yelan, a five-star rising star, has a surprise cameo at the end. We’ll likely see the Ruin Serpent boss drop materials related to their Ascension materials. And last but not least – don’t forget to pick up the luxurious chest located on top of the large, now reformed crystal!
