Perhaps I'm not into all the calculations of skills and dice rolls and other fancy RPG speak, but when I'm playing (360 version), I don't really focus on certain skills and stuff. I picked what I thought I'd use the most, and went with it. I also put Mercantile and Athletics because I'm always walking and selling things, why not get some free levelling?
I noticed it took me longer to get to levels this time around. First time I played, I was level 10 before I knew it. Right now I'm about lvl 5 or 6 (can't remember, Saint's Row is occupying my interest), and working my way to lvl 10 so I can get the skeleton key.
Has anyone ever found daedric heavy armor? The most I've found are daedric maces and hearts.
