Loot Highlights

- Mage Tower: Contains Amethyst Clusters, Glow Ink Sacs, and Diamonds.
- Fortified Village: Features profession-specific chests (Archer, Smith, Library) with significantly better loot than vanilla villages.
Items
While Terralith primarily focuses on world generation, it includes a few unique items found in its custom structures.
Royal Jelly
- Source: Found in Giant Bee Hives within Lush Caves or Underground Jungles.
- Effect: A powerful potion-like item that provides strong status effects such as Regeneration and Speed when consumed.
Traveler's Map
- Source: Found in various Terralith structures (Spires, Glacial Huts).
- Function: Leads the player toward specific biomes. It is programmed to favor biomes with the opposite temperature of the player's current location (e.g., a map found in a cold biome will likely lead to a warm one).
Mechanics & Ore Distribution
Terralith modifies ore spawning in specific biomes to encourage exploration and specialized mining.
- Emerald Peaks: Features a significantly higher concentration of Emerald Ore at high altitudes (Y > 100).
- Scarlet Mountains: Spawns with increased Redstone Ore.
- Volcanic Crater: Contains a higher density of Diamond Ore due to volcanic activity.
- Deepslate Transition: Ores automatically turn into Deepslate variants if they generate within dark materials, regardless of Y-level.
Terrain Smoothing
Terralith makes extensive use of slabs and layered snow to smooth out sharp terrain, making the landscape look more natural and easier to traverse.
Mobs
Terralith adjusts mob spawning to fit its new environments without adding new entities.
- Witches: Now spawn naturally in Terralith's custom Witch Huts, allowing for the creation of witch farms in these locations.
- Strays: Spawn in Frostfire Caves and Ice Marshes.
- Wolf Variants: All vanilla wolf variants are assigned to spawn in appropriate Terralith biomes (e.g., specific variants in Lavender Forests).
- Armadillos: Spawn in arid biomes like Ashen Savanna, White Mesa, and Bryce Canyon.
- Drowned: Spawn frequently in the water pools of Thermal Caves.
