Magic Circles - ISAS Addon

Did you heard about [Iron's Spells 'n Spellbooks](https://modrinth.com/mod/irons-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 small project was created in my free time as a student. If you like my projects, please consider to support me for more future projects and support!** # ## Important! This mod is published **only** on **Modrinth** and **CurseForge**. If you find it anywhere else, it is not an official upload by me, and downloading from those sites is unsafe. ## 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 (orange for fire, light blue for ice, dark purple for abyss, etc.). 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.
## (2026-04-11) 1.1.0 Update: Many bug fixes, new client configuration, new circle textures and animations but most importantly: [Iron's Spells 'n Spellbooks](https://modrinth.com/mod/irons-spells-n-spellbooks) backport version compatibility! (3.15.0+)
That means that from 1.1.0 version, the mod requires the use of ISAS mod of __version 3.15.0 or newer__. Magic Circles version 1.0.0 works and could be used for older ISAS versions.
