The way I've set it up so far is that Demons simply provide the raw energy, and thus a Witch is depending on her Demon's Magic Energy. I was contemplating for a moment that the Demon's ranks would affect a Witch's magical ability, but eventually decided not to.<br/><br/>I could go with the Demon lending power if you have a good way to make it work. Optional, the special ability that Demons already have could be extended so that they could grant Witches the same power, but that doesn't work out for all Demon powers. What kind of powers did you have in mind?
