CavesChaos: More Caves & Biomes
by FimeFire
CavesChaos: More Caves & Biomes adds dangerous cavern systems and rare underground biomes to the Overworld for NeoForge 1.21.1.
What it does
Cave biomes from the mod sit underground in the Overworld, where they are exceedingly rare compared with standard terrain biomes. Each one brings its own blocks, items, mobs and mechanics, and the caverns carry greater challenges with unique loot. It is a client and server mod, so the server and every player need it, and it is published for NeoForge 1.21.1 only. The code is not open source and is covered by All rights reserved.
Key features
Dangerous cavern systems
Underground cavern networks in the Overworld are built to be explored and carry more hostile encounters than ordinary caves.
Rare cave biomes
Subterranean biomes appear only occasionally, each filled with custom blocks, items and mobs.
Unique loot
Cave areas hold loot tied to their challenges, so harder exploration pays out differently.
