I've tried an dunmer spellsword who only uses Ash spells. But, when I finally got an ash spell, I hated it. The magic around the hand is way to big and distracting in first person. All over magic is alright, but for some reason the ash spell is like a cloud around your hand.
I tried an illusionist swordswoman. Who uses fear and calm as crowd control, but it felt really really cheat after trying it out.
I don't know if I want to do a fire and sword one, because that magic doesnt scale well.
Can people suggest an interesting swordswoman to try? Something that can catch my interest? Any help would be great, thanks.

. You could also mix this up with Restoration spells and pretend you're some sort of paladin by always using the anti-undead spells against draugrs while slashing away. Wards and flesh spells would be useful for overall survivability while paralyze is very fun (but cheap) once you can spam it.
