I am on "A Path Of Iron" quest and collecting Heaven's Fury armour pieces as told to do. I collected 5 pieces of the armour from various places and came to Lipsand Tarn for the last piece. I cleaned the place except for the vampiress boss, Ederiath Vrastal. However she is extremely difficult and i couldn't kill her after a fight of 40 minutes. I have a 30 level Breton character mainly relies on magic. As she is a vampiress, i mainly attack her with fire and conjure creatures that attack with fire but she is still standing. I don't want to use console command to kill her and i want to learn if she has a weakness which makes her easier to be killed.
Thanks
