Alex's Caves

Summary

Alex’s Caves is a Forge mod for Minecraft 1.20.1 that adds 5 new cave biomes to the Overworld. Unlike most normal biomes, these cave biomes are exceedingly rare - yet they all contain a variety of unique blocks, items, mobs and mechanics that makes them considerable subterranean destinations. These five biomes are the Magnetic Caves, the Primordial Caves, the Toxic Caves, the Abyssal Chasm and the Forlorn Hollows.
