The Corruption layer is, as of current, the deepest layer in the game, being located below the Lava layer. Its foundation is made of unbreakable glassy violet blocks called "End of the World" on altitude 0 that can currently not be mined/pulled. To get to this layer, players should at least be in possession of a Diamond Mining Cell (or a Lumite Mining Cell), as corrupted blocks can't be mined ("pulled") by anything less. Both Power Cells will lose durability when pulling corrupted blocks.
