Do any other DM's actually want their PC's to have access to this stuff? Or, is it just the principal of the thing (which, by the way, I'm fine with - PC's don't always have to be able to get whatever they want)?
I was planning on running this adventure, but I was not really concerned if the PCs get what’s in the box or not. I am pretty sure that my PCs will try to get the shiny prizes, and when they do then I will have Aubreck hire some other adventurers to mug the backstabbing PCs and take back his stuff. I love when the PCs give NPCs reason to hate them.
