This guide shows how to complete the objective “purify the large crystal” of 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.
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.
