My conjured dremora seem quite weak and die very easily from hits my storm atronachs easily survive. Furthermore, I can't seem to be able to conjure a 'potent' dremora lord. I only got the Atromancy perks. So I'm wondering, is the conjure dremora lord spell under necromancy or atromancy?
The Wiki suggests that there is no perk to raise the effectiveness of Conjure Dremora Lord
