NOTHING is impossible, (except for quests that have a level requirement), for a level 5 character. We have killed Umbra at level 2 using paralyze potions. The main secret is to level up skills while only sleeping when absolutely necessary, such as when joining the Dark Brotherhood. One of us has a saved character who is a journeyman of more than half of his skills at the sewer grating. It just takes a little work and patience.
