Elysium-API is a library mod for Minecraft NeoForge 1.21.1. It provides a robust collection of utilities, built-in features, and data-driven systems designed to simplify and expand the modification capabilities for both mod developers and modpack creators.

- Various useful Java APIs
- Utility Classes and Methods
