Catalytic Lib Mod provides shared code and core tools for dependent projects in your game. It works in the background to supply general routines that other content relies on. Installing this mod on its own does not change standard survival gameplay or world blocks. It serves as a necessary base file so related mods can run as intended.
Features:
- Acts as a core API library containing shared code for other mods.
- Runs quietly in the background without altering base gameplay.
- Supplies the necessary files required by dependent mods to function.
- Prevents crashes when launching mod setups that depend on this library.
