Cobblestone is a common block obtained from mining stone. It is mainly used as a building block or a crafting ingredient.

Variants of cobblestone include cobbled basalt, cobbled granite, cobbled limestone, cobbled permafrost and mossy cobblestone.

Obtaining Edit

Natural generation Edit

Cobblestone can generate in dungeons and parts of labyrinths.

Post-generation Edit

Flowing water that comes in contact with flowing lava can create a block of cobblestone. This depends on how far the lava source is from the water source, as it may create cobbled granite or cobbled basalt.
