Casting Crystals

 
Casting Crystals adds 1 new item, the Casting Crystal, which you can put Ars Nouveau spells onto and cast with a hotkey. By default, all 3 curio slots use CTRL + 1,2,3 respectively.

You can put spells into crystals the same way as Enchanter's tools. This mod also adds a few basic premade Casting Crystals to dungeon loot.
