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.

Compabillity:

The mod was built with care to remain compatible with other ISAS addons. If you find any incompatibilities, please open an issue on my GitHub and I will look into it.
