Cobblemon Ultra-Beasts [1.21.1]

This Cobblemon addon adds Ultra Beasts, incredibly rare, valuable, and powerful creatures!

Options:

New realm to explore: Enter the Chimera Dimension by travelling through mysterious wormholes — a dangerous plane inhabited by powerful Ultra Beasts.
Natural wormhole objects: Portals can appear organically in the Overworld, letting players access the Chimera Dimension without commands.
Encounters with Ultra Beasts: Discover rare, formidable creatures with distinct behaviors and a high difficulty to capture.
Progression and prizes: Earn bespoke advancements and other rewards as you find and capture these Ultra Beasts.
Built for multiplayer: Works well on servers — the system limits active wormholes so only one can exist at any given time.

Language options: The mod is localized in English and French.

How it functions

Wormholes have a chance to spawn randomly near players while exploring the Overworld.

Entering or interacting with one of these wormholes transports you into the Chimera Dimension.

Inside that realm, destroying a Core can trigger encounters with Ultra Beasts, which you can then fight and attempt to capture.

Successfully capturing Ultra Beasts grants special advancements and tracks your progress toward becoming the top Ultra Beast master.

Configuration

You can tweak spawn rates and intervals by editing the file “cobblemon_ultrabeasts_config.json”. Example settings:

{
“WORMHOLE_SPAWN_CHANCE”: 5000,
“TRY_SPAWN_INTERVAL”: 400
}

With these defaults, wormholes have a 1 in 5000 chance to spawn each check, and the check runs every 20 seconds.
