So I made a Breton Mage and was curious if I should focus on all the magic schools as a pure mage or skip a certain school for something better. Right now I have been running around with a single sword and a spell. Necromancer type mage, gonna go to the mages college and eventually join the dark brotherhood as a mage assassin.. Any ideas on how I can really build a mage assassin? Strictly for role play purposes (conjuration, destruction and alteration are must haves for me). But I'll take any ideas and maybe alter my ideas of what I want to focus on if I like it enough. Thanks in advance

Variety in the college of magicks is the way to go when playing a pure mage. illusion is esp good for getting out of tight situations and would fight nicely with the assassin side of your char.
