Gear Core
by fzzyhmstrs
Gear Core is a library for Fabric and Quilt that lets modders create equipment modifiers, which can apply entity attributes or track events such as taking damage, killing mobs and mining blocks.
What it does
Modifiers built with the library can add standard Minecraft entity attributes, and gear sets can combine them with custom attributes. Modifiers are not affected by grindstones, enchanting tables or other vanilla features, and they run on the Fzzy Core modifier framework, which chains them into ordered sequences where each one hands off to the next instead of only adding numbers together.
Selection probability can be tuned through tolls, and a modifier can be marked as unavailable for random selection, which suits innate modifiers that every instance of an item carries. Gear Core needs Fabric API, Fabric Language Kotlin and Fzzy Core, and Trinkets is optional. It is released under the MIT License, is open source, and runs on client and server for 1.18.2 – 1.20.1 on Fabric and Quilt.

Gear sets support Attributes, including custom attributes, and Equipment Modifiers. Currently only attributes can be added strictly via datapack, modifiers have to be created in code before being referenced in a gear set. Somewhere in my "want to do" list is datapack-based equipment mods, so stay tuned! And here is…
