Is there a xp glicth on oblivion

Warning You have to complete the expansion first.
If you are a warrior and need to upgrade through blade skill then you need to do 3 things:
1) download the shivering isles expansion pack.
2) Activate the strange door quest by going to it. (It's in Niben Bay near Bravil)
3) Attack the guard (Gaius Prentus) outside of the door.
He will not die just become unconscious and you will be able to do it again and again.
