One of the game’s main objectives is for players to upgrade their characters so that you can progress further in the game.
The upgrade requirements differ from hero to hero, but one constant material pops up (at least for Chongyung and Keqing) is the Cor Lapis.
Cor Lapis
These stones are a bit difficult to find, but the rewards of getting them and using it to upgrade your characters are well worth the effort.
They are shown in the general area as yellow ores that you will need to mine to get the actual material in your inventory.
You can mine these items; some are found under the cliffs in Liyue, while the other is in Mount Hulao.
Cor Lapis Location – Wuwang Hill
Cor Lapis can be found near the Wuwang Hill area. When you bring up the world map, look at the ledges or cliffs at the exact east and exact west where you will see the name Wuwang Hill.
In these general areas, you should be able to find Cor Lapis ores for you to mine.
However, one thing to note is that these ores can soak up a ton of damage before they break, so make sure you use your heavy attacks to break them.
Another thing to note is that some high-level mobs in some of these areas may be difficult for some to clear out. However, you should do this first before going on and breaking the ores. All in all, you would need around 168 pieces each of Cor Lapis to fully upgrade the 2 heroes,
