New caves
Glowing Caverns: Luminous caves full of glowing mushrooms that naturally light up the surroundings. They only generate beneath Mushroom Islands, creating a bioluminescent biome.
Rusted Depths: Oxidized depths filled with burnt stone, lava and a new ore: the ferrosite, can be used for decoration and hand drills. The rusted depths mainly generate in hot and desert regions.
Overgrowth Grotto: A dense underground jungle packed with giant toxic mushrooms, poisonous vegetation, and humid environments.
Frostbound Chasm: Icy caves featuring glowing ice trees and delicate crystal flowers that illuminate the cold surroundings.
Acid Catacombs: Corrosive caves filled with acid lakes and a unique radioactive mineral.
Each biome has its own unique mineral.
