About

Cobblemon Biome Expanded Spawns is a large-scale spawn expansion designed to make Pokémon feel naturally integrated into Minecraft's world.

Instead of relying on broad biome categories, each species can use detailed conditions based on biomes, dimensions, structures, terrain, blocks, weather, time, altitude and spawn position.

The result is a much deeper exploration system where changing environment can genuinely change which Pokémon you encounter.

Highlights

• 1,025 dedicated Pokémon spawn files
• 280 biome and environmental tags
• 34 reusable spawn condition presets
• Detailed biome, climate and terrain-based encounters
• Structure-aware Pokémon spawning
• Grounded, submerged, surface-water and fishing encounters
• Block, vegetation, ore and environmental conditions
• Dedicated Nether, End and modded dimension ecosystems
• Regional evolution and Vivillon biome logic
• PokéSnack-compatible spawn entries
• Extensive compatibility with major biome and world-generation mods
• Designed for large modpacks and multiplayer servers

Spawn Environments

Pokémon can use much more than a simple biome check.

Spawn rules can react to:

• Forests, jungles, taigas and grasslands
• Deserts, badlands and arid environments
• Rivers, oceans, reefs and submerged terrain
• Mountains, peaks and high-altitude areas
• Caves and underground environments
• Floral, lush and overgrown biomes
• Snowy, frozen and glacial regions
• Volcanic and thermal environments
• Nether fungal, basalt and Soul Sand ecosystems
• End forests, grasslands, crystals and barren environments
• Space, planetary and orbital environments
• Specific blocks, ores, vegetation and fluids
• Time, weather, light level and altitude

A species can have several different encounters with different conditions and rarity levels.

Structure Encounters

Some Pokémon can also be associated with structures and special locations rather than only traditional biomes.

Supported environments include locations such as:

• Ancient Cities
• Strongholds
• Woodland Mansions
• Ocean Monuments
• Ocean Ruins
• Ruined Portals
• Pillager Outposts
• Desert Pyramids
• Jungle Temples
• Trail Ruins
• End Cities
• Nether Fortresses
• Nether Fossils
• Bastion environments
• Deeper and Darker Ancient Temples

Compatibility is also included for selected YUNG's Better Structure replacements.
