Think a normal shield is too plain? Want some more magic in your world? Then this pack's for you!
Novus Magica aims to add some more magic into your playthroughs of minecraft, and does this using amazing Optifine features like CIT and CEM (CEM will come in future updates) (should work with OF substitutes too)

To get your magic circle shield, get a normal one and rename it to "Scarlet Magica" (example)
This Naming Guide may come in handy!
For some more fun with your shield, run this command (you can replace scarlet with any other shield: /item replace entity @p armor.head with minecraft:shield {display:{Name:";Scarlet Magica";}}

Optifine required.
