Chert

Chert is one of the stone variants found in Ceilum Biomes, and in The Encoren.

Chert is a common decor material, much like the original stone blocks found in every other biome. However it has some separate properties compared to other items.

Natural Generation
Chert can generate in the Overworld, specifically in Ceilum Biomes, in the form of mineral veins.

Breaking
Chert can be mined by a stone pickaxe or a pickaxe with stronger strength. If mined with a weaker pickaxe, it will drop nothing once broken.
