I have reached a Level 100 Conjuration and am able to reanimate two corpses to fight for me permanently, until they die whereas I can just reanimate them again. So I can have two more people fighting for me on top of a follower and a war dog I got from the Dawnguard DLC.
I want to reanimate both 'Sulla Trebatius' and 'Orchendor' because they're excellent! Once can heal himself, use magic as well as combat whilst the other is a long-ranged, teleporting badass!
I know where I can find them but I'm afraid their bodies may have dissapeared. If that's the case please tell me, otherwise I'll end up searching forever... in vain. :L
