Alex's Caves adds six new, very rare cave biomes to the Overworld: the Magnetic Caves, Primordial Caves, Toxic Caves, Abyssal Chasm, Forlorn Hollows and Candy Cavity. Each one brings unique blocks, items, mobs and mechanics, along with its own fog, particles and lighting.
Your journey starts at an Underground Cabin, where loot barrels hold cave tablets and the Cave Compendium guide book. Built for NeoForge and Forge on Minecraft 1.20.1, it requires Citadel and works with JEI and Alex's Mobs.
Underground expeditions with your group begin after a one-click install on your Minecraft server.
