Add-Ons are user-created datapacks that can add new content to the Vanilla Origins Datapack. They can also change existing content, but this requires more technical knowledge and an understanding of the file system that I maintain.

The base Vanilla Origins Datapack contains fairly extensive settings that change how the abilities of different Origins work or interact. They make use of Minecraft's global NBT storage to change the arguments of each function file controlling an Origin's abilities. Changes to the In-Game Settings should present on the next tick, and removal of data leads to unexpected, and usually unwanted, results. See Data Storage and Settings for more details.
