Re: Torg HERO - LONG, sorry!
I really can't add anything to the excellent post by Phil, but...
Don't forget that Possibility Points can also negate knockdown effects and KO effects.
As for Reality vs. Reality Skill during a Reality Storm, the winner each round would strip a certain number of PP from the loser. I don't have the chart here at work, but I would say (off the top of my head) each point of success in Hero would read straight off the chart from Torg. Once a person losses all of their PP, he would start losing levels in his Reality Skill until he was down to zero and transformed.
