Terralith Data Pack — Guide
World Generation Features
Beyond biomes and structures, Terralith introduces several geological features that aid in exploration and resource gathering.
Mega Features
- Mega Ravines: Massive chasms that can extend from the surface all the way down to Bedrock. They are excellent for mining but extremely dangerous.
- Mega Geodes: 2 to 3 times larger than vanilla Amethyst Geodes. Unlike vanilla ones, they do not connect to caves and must be found via strip-mining.

Cave Indicators
Certain surface features indicate specific cave biomes directly beneath them: * Andesite Boulders: Indicate Andesite Caves. * Granite Pillars: Indicate Granite Caves. * Diorite Patches: Indicate Diorite Caves.
Vanilla Overhaul
Terralith doesn't just add new biomes; it also tweaks vanilla biomes to improve their appearance and utility.
- Plains: Features more grass, tall grass, and rare patches of coarse dirt to look less uniform.
- Savanna: Includes rare "dirt paths" that simulate wildlife trails.
- Swamps: Overhauled with more mud, mangrove wood trunks/roots, and aquatic life like sea pickles and dripleaves.
- Forests: Trees have taller trunks to make navigation easier and provide a more open feel.
