I've ended up having to let my Dremora Lord kill everything for me just to slow down the leveling. I've only done the Companions quest and am near the end of the Winterhold quests. I've also killed a few dragons and gone into maybe four dungeons with this character...
I'm also using bound weapons and light armor as apposed to Ebony/Daedric just for a challenge, and because I don't like the movement speed while in heavy. Even though you can eventually make it weightless, it takes forever to hit 70 and your stamina still regens pretty slowly in comparison. By the time I finish with Enchanting, I'll be able to make Light Dragon armor that has a
much higher AR than what base Daedric can get, although it obviously won't be able to match upgraded Daedric. But who really needs more than 1500 AR + whatever the highest Stoneskin is?
Actually, for a real challenge I should just ditch my weapons and use Destruction abilities instead like I initially wanted to with my first character huh?

And yes, I'm playing on Master level, and it's easier than Destruction on Adept.
