Deeper Caves Mod adds many levels of caves below the default Overworld. At this point, there are (unfinished) Drop, Maze, Crystal, Compressed, and Bedrock Plains levels. All ore blocks on those levels have been added. However, Ametrine also does not have the mob-attracting effect, and there is no Molten Iron, just Lava in its place. Note: This mod contains a version checker.
