This mod adds many things to the underground!
3 NEW TYPES OF STONE
I know, there is already a bunch of stone types already, but these three are similar to the original stone and are simply a variation!
There is slightly cracked stone, cracked stone, and heavily cracked stone all of which are commonly seen everywhere (You might see them on cliffs and such!)
You can also cut them with a rock hammer to make them cracked!
NEW STRUCTURES
There are a few structures underground (Which I will likely add more later)
For example, there are broken ships that somehow managed to get underground with a special axe inside,
And rare obsidian spheres with 2-3 Darkbone ingots inside which can be used to craft Darkbone armor and tools!
OTHER FEATURES
When you go to bed you lose 2.5 bars of hunger, 3 variations of sand (Rocky, only available on version 1.12.2), A new random "music" disc, a dungeon, a shrine, and Flatheaded mushrooms (On surface)
MORE TO BE ADDED SOON!
