Fallen Lib Mod provides runtime tools and patch systems for Minecraft mod development. It helps other mods modify game code cleanly without clashing with base files. When running alongside the Apotheosis mod on version 1.20.1, it also lets creators add extra gem bonuses using data packs. Players typically install this library to support other mods that depend on its backend features.

Features:

Provides runtime utilities and code patching tools for mod creation.
Serves as a required base library for dependent gameplay mods.
Allows data packs to register custom gem bonuses in Apotheosis.

Mod Patching Tools:

FallenPatch hooks into exact classes or subclasses to reduce duplicate code adjustments.
FallenInserter connects custom hook methods to inspect or replace method return values during runtime.
Configuration files in JSON format manage required patches and version checks.

Runtime Utilities:

ObjectModifierFactory copies objects and adjusts numeric fields without altering the original object.
Delegated Mixin Connector Registry helps test conditional mixin setups directly in development workspaces.
