Wherefore Did the Spiritstone Descend Quest Guide: Genshin Impact 2.6

This guide shows how to purify the large crystal and complete the world quest “Wherefore Did the Spiritstone Descend” in the game Genshin Impact 2.6. Wherefore Did the Spiritstone Descend is the last quest of the ”The Chasm Delvers” quest chain.


Talk to Zhiqiong up ahead

As the quest starts, your first goal is to speak with Zhiqiong (NPC). You can find her south of the Nameless Ruins area at the marked location as shown below the map.

Go to the camp with Zhiqiong & Talk to Zhiqiong

After speaking Zhiqiong (NPC), she will ask you to come to the forward operating base of the exploration team. Head to this forward operating base to reveal a new portion of the map below Nameless ruins. At the forward operating base, another NPC (Khedive) tells you about a bigger crystal deep inside the mine, and as you yo investigate.

Go to the gate that Zhiqiong mentioned

Next, you need to go to the gate deep inside the new area as mentioned by the Zhiqiong. Keep following the river and dive into the mine to reach the location marked on the map. At the gate interact with Zhiqiong again and open the gate using the key to Stoney hall to complete this part of the objective.

Go within the gate to investigate

Enter inside the gate and investigate multiple locations. The first one is near a pile of books under a tent and another near a rock with a strange fossil photo. I have marked both the location below. Continue your journey inside the cave till you reach the Teleportway point. At this point, you’ll find a large crystal with ribbons of darkness (wave) around it.

Purify the large crystal (0/5)

Now, your task goal is to purify the large crystal. And for this, you need to locate five mechanisms around the area and charge them up with the help of the Lumenstone Adjuvant. The game doesn’t mark the exact location of five mechanisms, but you can determine the locations of the mechanisms based on where the ribbon of darkness from the large crystal is leading toward. 

I have marked the approx location of all five mechanisms. To activate the mechanism, you need to interact with each mechanism and stay beside it until it’s 100% charged. If move far away it will stop charging. A percentage gauge will appear above the mechanism for your reference.

You can permanently recharge a nearby totem first so that you can interact with it whenever your energy gets drained out. Or make sure to interact with the sources of luminosity around the area to help you recover the lost energy.

It is recommended to eliminate all the enemies present near the mechanism or spawn while activating it. Also, clear all the Oozing Concretions around the mechanisms using your Lumenstone Adjuvant.

Strike the large purified crystal

After activating all the five mechanisms successfully, glide toward the main large crystal to strike it. This will follow by a cutscene and the boss battle will commence.

Return to the camp and Talk to Zhiqiong

After purifying the large crystal and defeating the creature that emerged from the depths report back to Zhiqiong

Report back to Mining

Finally to end the quest talk to Mining outside the Chasm.
