It is a pretty simple suggestion and one which has been remarked upon numerous times. Bring back Dannato!
Who is Dannato? He is a friend of Verisgante, who resides in House J. Stroll up to Verisgante while in an undead form and Verisgante USED to offer you an option to talk to Dannato. In turn, Dannato would offer you all sorts of pale masters goodies in exchange for collectibles. Granted the randomness of the turn ins resulted in all sorts of stuff you really didnt need, but, sometimes you received Harm scrolls.
