My necro mage is primarily for PvM, not sure if that is your intent:

100 SS
105 Necro
110 Magery
100 SW
110 Meditation
110 Eval Int
115 resist

Frankly, it's a good damage producer but it fails a great deal on key high-level spells. I'd recommend dropping 10 points somewhere for 120 Magery and another 10-15 points for spellweaving 115. I'm trying to squeeze those in now...
