I'm not really sure how to distribute stats on him. I kind of wing it.
I do find that he builds up power ridiculously quick. At level 20 (or is it 21?), I'm putting up perpetual motion and one of the other two defense skills, dropping geometry, then hitting them with creative until I run out of focus. Destroys everything and refills my power. So even if I end up with no focus, I hit another perpetual motion. It's not a nuanced strategy, I'll admit.
