Would be a challenge, but with the Wabbajack to level your Followers, and a good Tank this could work, until the Archers come in lol
I don't use MODS considering I like my xbox version of skyrim more than my pc version haha.
Here's the ones I like:
Storm Mage where you use Lighting and ONLY Lighting.
Necromancer - Conjuration and a little bit of Sneak. Stand back in crouch whilst watching your Thralls demolish a dragon is awesome!
Witch - Specializes in Alchemy, Conjuration and Destruction.
One with Nature? Complete Alteration build :3
Just making things up is awesome, but this one is my ultimate favourite Unique mage build.
