Access the Configuration File
Server owners can fine-tune which Ultra Beasts spawn and how challenging they are by editing the mod's configuration.
Locate and open:
- Find
config/ultra_wormholes.jsonin your server directory - Edit it with any text editor (Notepad, VS Code, etc.)
- Save changes and use
/wormhole reloadto apply them without restarting
Adjust Key Settings
The configuration file lets you control:
- Boss roster: Change which Ultra Beasts can spawn from wormholes
- Boss stats: Modify level, size, and health multiplier to increase or decrease difficulty
- Event timing: Set minimum and maximum intervals between wormhole spawns
- Rewards: Customize what items players receive for participation
- Shiny chances: Adjust the probability of encountering shiny bosses
- Portal duration: Change how long the wormhole stays open after the fight
After editing, run /wormhole reload in-game to activate your changes immediately. This is useful for balancing difficulty across multiple boss encounters.
