The term Archdevil gained currency following the Trial of Asmodeus. It designates a title and a state of power attained by particular devils.
Archdevils acquire their immense power through promotion. Asmodeus, the System Overlord of the Nine Hells, is the sole entity possessing the authority to transform a devil into a supremely powerful archdevil.
