Bedrock is the only material in the game that cannot be mined with any pickaxe in the game, or with any other tool. It forms the boundaries, bottom (x=0 to x=1000), and sides of the map (y=0 to y=300). It can be placed and removed in Creative mode, but it can't be removed by mining in Survival mode. This material is a "protection" for evict falling into the void. Note that if you fall through it in Creative mode, you will die.
Bedrock has a 1 in 30 chance to be dropped by a Nethereye.
- It cannot be destroyed by mining in survival, or by explosions, so it works like a visible Barrier.
- The only way to break it is with creative mode, although this is not recommended.
- Outside the bottom bedrock is a thin layer of stone, liquids and ore. And structures can rarely be found.
- On the sides of the map, sometimes when you close and reopen the game, the bedrock will go from 2 to 1 block thick.
