LekLai
by MrSypz
LekLai is a Fabric library for building skill-based classes, adding a skill system modeled on MMORPG core engines, and it is in an unfinished state.
What it does
The author aims LekLai at a barebone library: most of its use is through the API, so other mods can build class and skill content on top of it. Its focus is classes and skill items, and the original Penomior stats system remains in place, with the balance of the class system still being tweaked.
Version 3.0.0 replaces the old refinement mechanic with classes and skills. The author has paused work for a while and is rewriting the animation system and a major overhaul of the experience progression. Dependencies are Cardinal Components API, Mod Menu, PlateauLib, Player Animation Library, Sodium and YetAnotherConfigLib (YACL). The mod runs on client and server, so both sides need it, and it is released under All rights reserved, which means it is not open source.
Key features
Class and skill system
Classes and skills replace the earlier refinement mechanic, with skill items used to build each class.
Dungeon-only experience
Experience comes from dungeons, so overworld mobs give none, a change the author made to ease balancing during development.
Preserved stats system
The Penomior stats system from the original mod still exists and is being tweaked alongside the class system.

Use cases
Building class content
Modders can use the library to add their own classes and skill items on top of the API.
Who it’s for: Players who want a class and skill progression close to MMORPG games, and modders who build content through the API. Development is ongoing, so some uploaded gallery material is outdated.
