Originally posted by Sesh:Oblivion Will-o-Wisps are impossible to kill if you can't dodge their attacks. This is the case no matter what level you are at. They are completely immune to normal weapons and steal 30 health and magicka an attack for only 10 casting cost. They aren't like the Skyrim Will-o-Wisps at all.
