A commoner has run into a LOT of money! Unfortunately, everyone knows it. Good luck getting out of town in one piece!
The local lord has been deprived of his prize family heirloom, the thief isn’t exactly a thief, but rather an absent minded wizard. Get the heirloom from the kindly but absent minded professor. Simple, right? Well, except for the fine print.
Other improvisational weapons/tools:
Icicles are useful as daggers,
Bag Of Holding filled with copper pieces used by chucking the contents at foes, (by strolen)
sleeves make useful garrotes. Ya can't cut anyone's neck, but you sure can choke 'em!
Flaming Logs make great clubs, (any Barbarians out there?)
and Bee hives are very effective when thrown at a mob of enemies. :-)
