This may get you a little bit of infamy but you need infamy to do a certain dedric shrine quest. When you get martin and bring him to Cloud Ruler Temple join then go to were every one sleep and wait for at least 4 people to be sleeping. Then punch one of them and then grab a sword and start attaking you do this untill you reach lv 100 in whatever armor your using or the desired lv If you stop and repair it helps with you armour. Also cst a protect and heal with spell that way you won't only be increasing endurence. Don't forget to repair swords that the B;ades drop otherwise your skill won't lv as fast.
In the middle of fights aslo dupe potions and repair hammers so when you get a lot of them you won't have to yield dupe and repiar cuz then most of them will probly be gone. So dupe in the middle of it then yield quikly go to inventory and reapir and if you need to drink some health and sorcery potions.
