Chad, just a note about your vampire. I swear I'm not picking on you.
It just makes me nervous whenever beings more powerful than your Average Joe walks into the bar.
I notice that he can manipulate energy somewhat, which is cool. Just remember that energy can't be spontaneously created. If it is leaving Fredrick for some other being that means that your character is losing energy. The amount of energy that it would take to heal someone, then, would probably result in severely debilitating your character, for at least a little while. At the very least it would probably make him extremely tired.
That seems to be the most logical way to deal with energy manipulation, in my opinion. I might be wrong, though. I just figure it's a safeguard against potential powergaming (not that you've done that. You haven't. It's more of an insurance thing
).
