About this Mod
Overhauls the existing underground and Badlands mineshafts into a more interesting experience for gameplay, visuals, and rewards while maintaining a vanilla feel.
Loot is neither underwhelming or overpowered and is largely the same save for Fortune and Efficiency enchantment books, TNT ingredients, and haste potions.
As a consequence of using jigsaws and not being hardcoded, these new mineshafts will no longer spawn beneath river or ocean biomes.
Now includes:
- TNT and TNT cart mechanics.
- Archaeology! Be sure to bring a brush for a few extra goodies.
- More minecart types! This includes the largely forgotten about spawner minecarts.
- Variety and distinction between individual and especially the kinds of mineshafts themselves.
- Cave spiders replace normal spider spawns in mineshafts.
