In Genshin Impact, there are all sorts of mineral deposits scattered around the map.
One of them that you may need to find is crystal. You can get lots of crystal chunks at the right area.
Here’s how you can find crystal chunks in Genshin Impact.
How to find crystal chunks
Crystal chunks are generally located all around the map.
You can however find clusters of them in Stormterror’s Lair. You will come across this place when you do the final quest series in the Prologue.
The location is shown in the map below, marked by the player location (red circle). This is just one of the few areas in this map.
To get the crystal chunks, destroy the crystal deposits.
Use a character with a heavy weapon (e.g. Claymore) to destroy deposits quickly.
