Been mining for ages and got too much cobble? Sick of that dirt hut? Superbases are for you!
First thing you need to know: You need a LOT of blocks! Usually, you'll need to make a cobble farm, wood farm, and/or some other type of block farm.
If you built near an ocean/deep ocean biome, just get a lot of signs, sponges, cobble, and glass, then dive and build! Usually, you should also get LOTS of night vision potions, no matter your game mode,and in Survival, water breathing. While you're down there, just make a mini base with a brewing stand, torch, crafting table, and bed. When you're finished dry the whole thing out!
