This data-pack features all data from the base Pixelmon mod allowing you to customise every aspect from the old external JSON file system on the previous version.
You can edit everything from trainers to biome spawn locations with the JSON files included, make sure to install this in the data-pack folder to make any necessary edits.
This also serves as a detailed guide in how to add your own data to this.
