I can't remember how to get into the small chests in the castle without lockpicking and how to get into the small treasure room in the upper right hand corner... anyone know?
The chests can be brought to the cellar of the north west building in the castle complex (where magic is allowed) to lockpick, or tossed over the wall / through the front gate to get later. You can not get into the small treasure room, at least without cheating; Teleporting Anywhere, via hex editor
