I also was unaware that a) 4 AP magic skills exist b) AP upper limit is actually hardcodeD?
A bit OP is not too bad. Especially considering enemies might get them too.
In my opinion, a bunch of them need some tweaking to be balanced. My opinion is not that only the three I described simply as broken/OP are the ones which would need fixing.
I don't know if 4 AP skills exist. But neither do you. What I do know is that we're only seeing "Act 1" skills, not high-powered, up-to-10-Memory-Requiring end-game skills, some of which might require 4-6 AP. I'm also pretty certain that the 4-AP per turn and 6 AP max is indeed fixed barring specific exceptions (Glass Cannon, Adrenaline).
