Enough criticism, here are some tips.

The two most powerful weapons in Oblivion are swords, and are obtained through Daedric Shrine quests.
The first, Goldbrand, can be earned by completing Boethia's shrine, in which you fight ten separate opponents in a row. These enemies drop many riches of their own, making this shrine one of the most profitable. Goldbrand has a very high melee damage plus a +20 fire damage enchant.
The second, Umbra, you come across during Clavicus Vile's Daedric shrine quest. You must kill Umbra and take her sword (she renamed herself after the blade). Vile requests you bring him the blade, which would yield some great light armor, but you can instead ignore him and keep it. Umbra has the highest melee damage of any weapon and inflicts a two minute soultrap.
