When you see a mob, sneak up on them slowly and draw them out one at a time! Once one sees you, slowly walk backward and draw him toward you, strafe left or right to dodge the ranged or magic attacks. Once you lead this one far away enough from the fray, kill him, then rest and let your health regenerate itself back to full.
Then repeat again and again and again...................until the mob/area is cleared.
This helps when the baddies are 2 or 3 levels higher than you(as in your case).
Play this game slowly, and you'll really enjoy it!
