It involves a great deal of trial and error, along with enough deaths to fill Shor's Hall twenty times over. Eventually you get used to it, adjusting to more subtle styles of play (sword and board is not the best idea on master, unless you're a gaming god). I would recommend summoning familiars, atronachs, and dremora as often as you can to avoid being the only target when you're outnumbered. Take a follower along on your journeys as well, especially if they happen to be an immortal punching bag (Mjoll, my darling!). If your foes get too close for comfort, dance like maniac. And keep a sharp eye out, since ambushes seem to be more frequent on master difficulty, for me at least. It's like my enemies can smell my fear...
