Where to find the Clay Claves Biome
If you want to find the Clay Caves Biome, you can do so by exploring and mining. But, to mine in Core Keeper, you will need a Pickaxe. You can get a Pickaxe by making one from Wood and later Copper when you get Copper Ingots.
When you getPickaxe, start mining until you reach an area with slight orange coloring on the map and terrain. Both are key indicators that you’ve found the Clave Caves Biome. Another indicator is the words that will pop up on the screen that displays the biome name.
