Who plays with which heroes in the Inferno faction?

I wonder, is there a hero with the Archdevils specialty?

No, of course not; that would make him an overpowered hero, although only in the late game.
For me, there are 4 dominant heroes for Inferno. Deleb, Nimues, Nibros, and Jezabeth.
By the way, I'd like to hear players' opinions about "Grok." What do you think of him?
