"Zadrei begins with one rank in Spell Craft and can increase it at levels 6, 11, and 16."

I just didn't write it at the top because I didn't think it would be necessary.

As for how his R works, he doesn't "save" the spell so he can cast it repeatedly like Invoker, but rather casts it immediately and then "forgets" the spell until crafted again. And you might need some quick fingers to craft a spell without afkaing, but if you know what you want it takes around 1 second to craft it (which at one stage of the concept was the cooldown of his R at max rank).

One thing he does better than most mages is versatility, what other mage has a stun (which can be targeted, long range or even global), heal and CC removal, sustain through draining, resistance shred or buff (forgotten interaction between Reverse and Weaken components), and still has potential to deal high damage?
