NOTES 📝: This mod is currently intended for modpack authors who are comfortable creating and editing JSON files.
Superior Modular is an addon for Truly Modular that adds modular material effects, Irons Spells support, workbench stat display changes, and some other small QoL features. Future versions will have dozens of new modules, a Workbench UI overhaul, and hundreds of built in materials.

Features: ✨
- Modular material and gear tooltips for Spells and Material Stats
- Iron's Spells 'n Spellbooks compatibility: Modular materials can automatic spell cast abilities to your gear. Spell casts do not trigger their casting animations so spell casts do not interrupt swings and attacks
- Better Combat Compatibility: Attack-based spell casting supports both vanilla and Better Combat swings. Epic Fight compatibility coming soon
