Thanks for answering, and that quickly, too! There are not many games in the world where you get the rules explained by their inventor within a quarter of an hour, that's so cool!
Sorry I wasn't clear, I knew that POW is the generic term for MAG/PSI/CHI. I realized shortly after posting, that my question sounded dumber than I meant it xD
I just meant the rest of your answer, so thanks again!
