Stop Specific Mobs from Spawning in a Biome
Open the Crowd Governor Menu
Press the mod's menu keybind (configurable in your controls) to open the Crowd Governor interface.
Navigate to Biome Bans
Locate the biome management section. Select the biome where you want to prevent spawning—for example, your base biome or a peaceful area.
Ban the Mob Type
Find the mob you want to block (Creepers, Zombies, etc.) and toggle it to banned or disabled for that biome. The mod will prevent that creature from spawning naturally in that location while allowing it to spawn elsewhere.
Apply and Verify
Confirm your changes. The ban takes effect immediately. You can verify by waiting in that biome—the mob should no longer appear. If you need to ban the same mob across multiple biomes, repeat these steps for each location.
Global Alternative
If you want to ban a mob everywhere at once, use the global ban feature instead of per-biome settings. This is faster for mobs you never want to see.
