Bedrock is the only material in the game that cannot be mined. 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".
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.
- Below bedrock is a thin layer of stone.
