FAQ

Do Cobblestone Generators Work AFK?

The block will continue to generate itself, but if nobody mines it, you won’t get the sweet pieces of cobble you need. So, it just generates the material - it doesn’t mine it.

Can You Mine Cobblestone Without a Pickaxe?

No. If you use another item, it won’t drop anything. Besides, the mining process will be much slower, so bringing your pickaxe is the best choice for you.
