You're magic/health/stamina should be like this: 3/1/1 (for every three points into magic, put one into health and one into stamina).
This character forces you to use tactics in order to survive, like casting Fury as a detraction, then making yourself invisible to sneak past the enemy. Or maybe use Oakflesh followed by Rout so you can slash the baddies as they run, and won't have to worry about some random arrows from the cowards friends.
This is just an idea, feel free to criticize as you see fit.
