This also brought another question to my mind, "If Dovahkiin summoned Vile fully and beat him, that would be the 2nd time Vile was beaten by a mortal (Cyrus & with the Hoonding) yes both times with the help of a god yes, but mortals none the less.
So what im asking is, is Vile really just that weak or are these just unfortunate circumstances be was in, & is the Hoonding/ Dovahkiin/ any other gift of power from the gods really THAT powerful?
