champions-alter
Champions Alter, a NeoForge add-on for Champions-Unofficial, lets a world set how often champion mobs spawn, using KubeJS scripts and a server config file.
What it does
Champions Alter is an add-on that controls how often champion creatures appear. Spawn rates can be changed while the game runs through KubeJS scripts, and staged configurations are set in champions-server.toml. Champions-Unofficial is required, and KubeJS is optional: a world without it still gets the config-file controls, but the scripted changes need it.
The mod is built for world generation and adventure worlds where the champion population should change over time, for example at set stages of progress. A script can make a large number of high-level creatures spawn in the world, and the author notes a modpack built around these settings. The author's tutorial images and partial scripts are linked from the project page for players who want a starting point. Files are published for NeoForge 1.21.1 only, and the project is not open source: all rights are reserved, though the source code and issue tracker are public.
Key features
Scripted spawn rates
Champion mob spawn rates are adjusted through KubeJS scripts, so they can change as the world develops.
Staged configuration
Spawn settings are grouped into stages, which are defined in champions-server.toml and applied in order.
Default stage behavior
New stages apply their defaults automatically, so a world can set spawn rates before any script is written.
High-level creature control
A script can make large numbers of high-level champions spawn across the world, as shown in the author's example.
