Delvecraft!

This is a cave update mod, made using MCreator. Basically what it does, is adds a bunch of new features to caves. This includes brand new rock types, such as slate and marble, different stone blocks depending on the biome you're in, new mobs, like Skeleton Miners, Silklings, Lurking Spiders and a new boss, the Spider Monarch.
We have fossils, rubies, which can be used to make ultra cheap beacon bases, mud blocks, moss, brick and pillar variants for andesite, diorite, and granite, shingles, a new type of brick and so much more!
