I want to play a Necromancer that is also able to blast his enemies in Oblivion, therefore that uses more Negative Energy attacks rather than summoning undead. I'd go for focus in Evocation and Necromancy (and for going archmage or red wizard of thay I have to select one), but I'd have to select no less than 6 feats (2 base focus, 2 additional efects ilke Piercing evocation and Fearsome Necromancy and Greater Focuses to name the first)... too much. can you help me? While spell penetration overcomes spell resistance spell focus works against savnig throws... which would be more profitable?
