At Arcantas's mention of taking inventory of powers Argus speaks. "You said you summoned fiends and made the dead walk. I did the same for the most part. I also studied some combat magics but those are mostly suppressed except for one little trick." With that, he conjured a fireball the size of his palm before extinguishing it. However, Argus failed to mention his crowning achievement of sacrifing his soul not to a fiend or a dark god but to the void and the dark arts themselves.
