I wanted to do something different and try out a necromancy build. I used destruction on my main character but learnt how it didn't scale and no I'm not on PC so I can't download the rebalance mod. What skills could I use in this build and any tips?

Use the other thread.

Other thread? Why is there a dedicated build thread?

Ah I see which one you mean, I didn't see it...

Destruction, conjuration, some restoration, maybe alteration and alchemy?
