Skills Perminentaly up!
(This is very similar to the process submited by daniel007)-The easyest way to do this is: In the starting town, go to the tradehouse and buy the spell "Jack of trades".
After this go to the mages guild in Balmora, buy the "soul-trap" spell from one of the mages there, talk to the Highelven woman in the green robe who can make spells, choose the attribute you want to be up'ed and set the magnitude 20-20, 50-50 ect, change it's cast to self CHANGE NOTHING ELSE, set "soul-trap" to on target, make the spell, face up against the wall and cast it (your selected attribute should go up)!
