deathknight. also that warlock who did that used sargeras’s staff made for portals plus spells from medievh the last guardian a god mode mage and using gul’dans skull hyper fel magic infused at the black temple which has a ton of magical leylines connected. deathknight is basically unbeatable if we go by lore reasons. legtit that orc wasnt a warlock he was a shaman and that entire plotline was legit just the orc storyline for warcraft 2 beyond the darkportal and told in the novels of the same name.
