Oblivion: How to kill Umbra on Hardest difficulty (character profile included)?

if you want to beat umbra, your going to need to better your brenton. umeing you want to kill her exploit free , i would reccomend the wambajack . I believe it comes from the sheogorath daedric shrine quest. Get your brenton to the level required and do the quest. Go back to umbra and Hit her with it. It should transform her into some sort of weaker creature (she will turn back to normal once dead). you will be able to take her on much easyer from their. Id have a few health/magika potions around and cast your racial spells just incase. If this doesn't kill her, nothing will. Also if you do end up killing her, make sure to take her armor. Its awsome
