Shadowstrider, did Bethsoft make casting spells "cheaper" depending on your skill in the different magic schools? I always hated that in Morrowind how I was a Grand Mage but I couldn't use my magic any more efficient than a initiate..
EDIT: Btw, I managed to kill a guard by mistake and will get my "invitation" to the DB soon. Should I go for it? My character is currently a customised spellsword, Blade, Heavy Armor, Destruction, Illusion, Alteration,Conjuration and Sneak. Can a character such as mine do the DB quest without way too much hassle?
