I think you're right. Also playing my first time thru today and had the same questions. But meno can't be stunned during his turn. He becomes un stunned at the beginning of his turn.
Also, can pillars gain more than four health?
Good catch! I wasn't playing that he "un-stuns" but that rule comes to mind now. That makes a big difference.
I was playing that the pillars can gain more than 4 health but I'm not sure on that one either. Good question.
