I did Bloodmoon the other month with a level 13 Spear Argonian and all the enemies were really tanky and I died very easily. There's a tomb which you immediately get attacked by 4 werewolves upon entering and they would kill me before I could attack, so to get around it, I enchanted an amulet with fireball and would enter, cast it and immediately leave. Had to quicksave a lot though. There were lines upon lines of wildlife waiting for me whenever I went anywhere and I got the Redguard woman, who you save from the Nords, killed by accident when I re-aggroed one of these lines. If this happens and you report to the Redguard priest, you later find him dead with a suicide note on his body. The Bloodmoon expansion is pretty easy if you become a werewolf, though the ending's still the same.
