The levelrange must be defenitly wrong, as there are Crusaders, I cant control with Dire Charm. As the spelldatabase tells, that that spell allows Control upon NPCs (Ench) up to Lvl 55, there have to be some above 55. (And there are a few of them!) ...
I would only be wrong, if the found Dire Charm (Advanced Dire Charm) isnt the same as the AA-Dire Charm.
Anyone can proof my thoughts upon that?
