I've been struggling with this too, I can't seem to fix it. I've tried removing the spells listed in my log, it didn't help. I don't know what to do, maybe a picture of my character with the effect around him will enlighten some of you. By the way, I've found a save where this wasn't happening yet and I haven't added or removed any mod since then, except for autosave manager which has nothing to do with magic effects... Really, I haven't done that much, probably killed a dragon, finished a part of that quest where you have to find pieces of Mehrune's razor, stole a bunch of stuff. My equipment is the same, too. I will revert to that save if need be, but I'd rather not if possible. EDIT: Got it. Frost Atronach. Somehow I had missed it in the first page. Still, I wonder how in Oblivion this effect got stuck on my character... Anyway, thanks for the incredibly useful thread, steve40.
