Underground Biomes Mod — Reference

Blocks and Variants

Every stone type comes with a full suite of decorative and functional variants.

• Cobblestone: Dropped by Igneous and Metamorphic stones when mined without Silk Touch. There are 16 types of cobblestone in total. Sedimentary stones do not have cobblestone variants.
• Bricks: Crafted from smooth stone. All 24 types have a brick variant.
• Slabs, Stairs, and Walls: Available for all stone, cobblestone, and brick types.
• Buttons and Pressure Plates: Available for all smooth stone and cobblestone types (bricks do not support buttons).
• Gravel and Sand: The mod adds 24 variants of gravel and sand to match the local geology.
• Monster Eggs: Silverfish can hide in any of the 24 stone types.
• Mossy Variants: Mossy cobblestone and mossy bricks are available for all applicable stone types.
• Overgrown Stone: Compatible with Biomes O' Plenty, adding grassy/overgrown versions of the stones for surface transitions.

Items and Resources

Mining in Underground Biomes provides more than just building blocks. Several stones have unique drops:

• Lignite (Item): A low-quality coal dropped from Lignite stone. It can be used as fuel in a furnace, smelting 1 item per piece.
• Fossil Piece: A rare drop found when mining Limestone, Chalk, Siltstone, Lignite, or Dolomite. These can be crafted into Bone Meal or kept as decorative items.
• Flint: Frequently drops from Chert instead of the block itself.
• Clay: Occasionally drops from Shale.
• Rare Nuggets: Deep-level Igneous rocks have a very small chance to drop Gold nuggets or other modded metal nuggets.
• Gems/Dust: Deep-level Metamorphic rocks have a rare chance to drop Lapis Lazuli or Redstone dust.

Recipes

Most recipes follow the standard vanilla patterns, substituting the mod's stone types for vanilla stone.
