I've been working on a two-handed / Restoration warrior, and I see there is a perk to turn higher level undead with Necromage. I realize that a spell like that is pretty exclusive to barrows and such, but I've found that it can come in pretty handy in places where you get swarmed by multiple draugr. I was just wondering if the Necromage perk is worth taking in that regard? Has anyone turned a Deathlord with it? Scourge?
