I’m not really sure. I had tried to maintain a balance between physical skills and spells, but it’s rather difficult figuring out the rights one to pick that can work along with the other characters.
Respec always exists if you don't like a build, but it depends on the build and ally a bit. Something like manablade or athame are hard to go wrong with, but as far as stats go I tend to go for 1-2 offensive stats and 1 defensive stat for a chill run. Depends on your setup tho, magic is *really* versatile, and some of the newer martial arts (or harp) have freebie channels that can help.
