I was stunned to discover, as the result of a thieves' guild quest, that there is an almost complete set of glass armor in the Ald'Ruhn Mages' Guild smith's room (sitting out in plain sight, no less).
I was even more pleased to realize, that given a fairly high sneak skill, I was able to sneak around right under the smith's nose and loot at will. You gotta love that skill. After a certain point, there are few things you can't lift. I didn't get caught, hence took all the goodies and kept my good standing in the mages' guild. Shiny! [img]tongue.gif[/img]
I just restarted, and I have to remember to pay a LOT more attention to the stuff lying around in plain sight than I did the first time through.
