champions-alter
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
This is an add-on for the Champions mod, which allows you to easily control the spawn rate of champion creatures.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.21.1 on NeoForge. On other versions it may install and then do nothing.
This mod allows you to dynamically control the spawn rates of champion mobs through Kubejs. You can find the configurations for the spawn rates of champion mobs provided by various stages in champions-server.toml and configure them via Kubejs.
(KubeJS is optional, but if you don't install KubeJS for modifications, this mod will have no effect!)
By default, you can apply new stages in Kubejs to control the spawn rate of champions.
You can refer to the images below for partial script tutorials.
For example, if I set the stage to Kether, a large number of high-star creatures will spawn in the world (if possible).
This mod was created for the Reverie Foundry modpack!
