Did you heard about [Iron's Spells 'n Spellbooks](https://rhs.millered001.workers.dev/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. This mod is a part of a bigger project to be released this year~~

I took some time off from studying/working, to create an ambitious modpack to test my skills as a game maker. If you are curious, I would appreciate it if you consider joining my Discord group that I have opened for it.** # Discord: [https://discord.gg/McYBqCNbnd](https://discord.gg/McYBqCNbnd)

## 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. Also important to mention: From version 1.1.0, the mod requires the use of [Iron's Spells 'n Spellbooks](https://rhs.millered001.workers.dev/mod/irons-spells-n-spellbooks) mod of __version 3.15.0 or newer__. Version 1.0.0 works and could be used for older ISAS versions. ## 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.

## (2026-05-31) 1.2.0 Update: Oculus shaders support and many other bug fixes. This has been released as a new version because most of the mod has been re-written. I have updated the gallery to showcase how the latest version of the mod looks in vanilla and also with shaders, using the new default config.
Also there is now a [Discord](https://discord.gg/McYBqCNbnd) server for this mod. It would also be used for other mods i would make soon.

Check out the project [GitHub](https://github.com/or1904/Magic-Circles-ISAS-Addon/tree/main) for full changelog.

**Cant believe it reached 10k downloads on Modrinth. TY for downloading!**

If you find any incompatibilities, please open an issue on my [GitHub](https://github.com/or1904/Magic-Circles-ISAS-Addon/tree/main) and I will look into it. Shaders compatibility - version 1.2.0 should support most Oculus shaders. Tested with:
