When Rood was in normal Blow form, he is on par with Shic. When he's Awakened with his original power, he becomes even more powerful. Technically, we believe that the demons should be stronger than the Awakened Magicians, because they're the origins of Magician power, but, you'd never know. :D *stares at Shic* Some humans can probably train well enough to become as strong as a demon?
Unless, you were reincarnated from a demon, like Rood. You kind of get a free pass on being "very strong among the humans". However, I think Meredith may just be very strong among the humans too.
