Reliquified Twilight Forest new relics fix is an unofficial compatibility mod for Minecraft 1.21.1 running on NeoForge.
It fixes Reliquified Twilight Forest 0.5.3 when used with newer versions of Relics, particularly the 0.12 series. The original add-on still references classes and methods removed from the old Relics 0.10 API, causing errors during mod loading and Mixin application.
What does it fix?
- Fixes the
EffectRegistry.STUNerror inChainBlockMixin. - Redirects legacy references to the current Relics API.
- Adapts relic definitions, stats, leveling, and abilities.
- Provides compatibility with current runtime components and data.
- Preserves Curios integration and relic rendering.
- Adds translation aliases for relic descriptions and attributes.
- Does not modify or replace the original mods.
The compatibility mappings are applied early through a coremod, while additional Mixins provide the required runtime adaptations.

- Minecraft 1.21.1 or newer
- NeoForge 21.1.93 or newer
- Relics 0.12.8 or newer
- Reliquified Twilight Forest 0.5.3 or newer
