Mod Features: 11 Cave Biomes

This addon is a true unofficial “Caves Update V2,” adding a massive amount of new content. You’ll find not only new landscapes but also new ores such as titanium, cobalt, and palladium, new weapon types like kunai and greatswords, and many useful tools — from magnets to drilling rigs. To ensure all mod functions work properly, you must enable certain experimental features in your Minecraft PE (Bedrock) world settings.

New Cave Biomes

The underground world is now divided into 11 unique zones, each with its own features, resources, and dangers. Exploring the caves has never been this thrilling and unpredictable.

Crystal and Resource Caves

Deep underground, you’ll find Jasper Caves with red crystals and Kyanite Caves with blue ones — which can be used to craft throwable kunai. Slime Sewers serve as an endless source of slime, while Lichen Caves glow softly with bioluminescent moss. In Sodalite Caves, you can mine a new blue gemstone and its energy-infused version for crafting.

Dangerous and Hostile Biomes

Be cautious in the Spider Caves, filled with webs and nests that spawn explosive baby spiders. The Horrid Caves are overrun with spore blocks and a new hostile mob — the Hallow. The deadliest zone is the Withered Garden — a twisted version of lush caves inhabited by wither skeletons and home to the mod’s final boss.

Peaceful and Glowing Oases

Not all caves are dangerous. The Glowing Mushroom Caves, found only beneath mushroom islands, are peaceful havens. The Shimmering Lush Caves and Aether Caves are always brightly lit, preventing monsters from spawning. The latter are also home to a new friendly mob — the Pixie, which can be tamed.

New Mobs and Boss

The underground world is now inhabited by many new creatures — both hostile and helpful — and at the heart of the Withered Garden awaits a powerful boss.

New Denizens of the Depths

Among the new enemies, you’ll encounter Weeping Angels in abandoned chapels — they are immortal unless you’re looking directly at them. Molten Zombies leave a fiery trail, and Raider Miners can break blocks to reach you. On the friendly side, tamable Pixies and Luminous Allays can assist you by lighting your path.

Boss: The Floral Amalgam

In the Withered Garden, you can summon the boss — the Floral Amalgam. This opponent uses a wide range of attacks: summoning poisonous spores, launching spikes from the ground, and making rapid charges. Defeating it rewards you with a crafting template for Exodium — the strongest and most durable gear in the mod.

New Equipment and Items

The mod adds a vast variety of new gear, weapons, and tools that will aid you in exploring Minecraft PE’s (Bedrock) dangerous underground world.

New Armor Sets and Weapons

You’ll gain access to armor sets made from Titanium, Cobalt, Platinum, and other metals. Two new weapon types appear: fast-throwing Kunai and powerful Greatswords that deal massive damage but temporarily weaken you after striking. The ultimate goal is the unbreakable Exodium set.

Useful Tools and Structures

While exploring caves, you’ll come across new structures: the Crystal Tower, Labyrinths, Underground Outposts, and Ancient Forges filled with valuable loot. New utility items will help you on your journey — an Item Magnet for collecting drops, a Miner’s Helmet with a built-in light, and even a 10x faster Golden Minecart for quick rail travel.
