About this project
What does Neo Magic Circles - ISAS Addon add?
Did you heard about Iron's Spells 'n Spellbooks? Did you have moments you saw players, mobs, casting powerfull spells but… something was FEELING missing? Well this mod just might gives you the answer!
This is an unofficial NeoForge 1.21.1 port of NoEndMan's original Magic Circles - ISAS Addon
✨ Features
This is a lightweight, client-side, cosmetic-only mod that renders magic circles when casting spells!
📖 How does it work?
The mod uses several magic circle variants, each with a different size. The variant is determined by the cast time of the spell: longer cast time → larger magic circle. If a spell is cast instantly/doesn't have a cast time, then no magic circle would be displayed for it. The color is dynamically chosen based on the spell's class. The position of the magic circle is also affected by the chosen variant.
Magic circles are displayed for any entity that is casting and only clients with the mod installed will see them.
🎨 Want a Different Look?
This mod ships with the original Magic Circles art by default. If you'd rather have Fullmetal-Alchemist-inspired transmutation circles instead, grab Iron's Spells & Spellbooks: Transmutation Circles by HappyMeek - it overrides the same texture paths this mod uses, so it works as a drop-in resource pack on top.
🔧 Compatibility
Shaders compatibility - built with native Iris support, so circles render correctly instead of breaking or disappearing under a shader pack.
