If you like numbers so much maybe I should've used old system which was more numbers heavy...

[@RoflsMazoy] About your CS: You don't get to have more magical aptitude than being born Ashan. After that it's only practice.

Change the duration of your fire magic to 5 posts, not minutes. And do you give bonuses to your enemies or penalties to your allies while in overlimit? Also, the additional effect is troublesome. As things stand all your spells will already be lv.5 while your fire magic is activated, supercharging won't do a thing for them. 

Your Wind Magic is unnecessary, you can levitate perfectly fine with your wings. 

Lightning bomb is fine as is, I don't see why you think it's overpowered.

Textbook magic is a no. It's too broad.
