Dwarves versus Necropolis.

7-8 months? Come on, in that time, a Necromancer can defeat three Dwarves, not just one. If you're still planning to play like that, I would suggest focusing on Darkness skills (with a Sandro's Cloak found somewhere and necessary spells like Subjugation and Berserk). Also, max out Defense until it's ready, Charisma until Distraction (otherwise, it will be difficult to compete with the Necromancer in magic), Education, and then Light or Attack (it depends on how the Necromancer is developing; if he's going into Darkness, I would take Light with Blessing). I think that's the way to go.
