hmm probably, but his blood is fel and demonic, its not neccerily through magical will that it happens, but ime nto sure he has comparable magic powers to Ner'zhul, i know he is a mere Orc in this which does not neccerily seem as impressive as massive mannaroth the pit lord but Nerzhul does have a great deal of power
hmm not sure, i wonder what Darth thinks, at the moment i dont know all of Nerzhuls powers myself, to me he, plus all his oher forms, Lich king and fusion has not got a set bunch of powers (once again maybe because ive not read the books?)
i mean we know things that certain paladins have, Arthas powers, Mages but Nerzhul, isnt he a shaman? did he ever touch the old warlock magic killy offered? so if he has he may have some of that and shaman but ime not sure, but that would be powerful, shaman and warlock
