What does a perception check really signify? Can they be repeated?
I would disagree here. If I lose my car keys and fail to find them I would keep searching ... now I might have left them at work in which case I am not going to find them at home. If characters are searching for something they are not sure is there the DM should roll but I dont think a missed skill check should stop them from looking again.
Divine / Arcane scroll use
Actually I think this section answers my question and gives a very clear section in the rules to point to. A wizard cannot normally use a clerical scroll even if it is on his spell list.
