This is a Hex Casting addon which includes several things that have been migrated from my other addon, Oneironaut(which I strongly recommend you also download if you're on Fabric/Quilt), as well as an assortment of new content, such as:
Instant Aegis, a spell which conjures temporary armor in any empty armor slots. This armor can even apply a status effect of your choice, for great versatility.
A set of patterns, and associated blocks, to make Hexal's link system useful for more than just data transmission.
A spell to make a wisp fire a plasma beam, inspired by Noita
