Hmm, I don't think you can kill a paramite if you unpossess it. Unless you fall of from a cliff. A slig you can kill when you unposses it.
What's so cool about Shrykull? Because he's a God or something? It woul be mad gravy if he could do other things too. Also, they say he's half-God half mudokon but I think he's half paramite, half scrab!
