Feather quest

A mob says to you 'I apologize, but I can only make the fletchings out of feathers.' This amazingly rare feather plucked from the hide of an owlbear is highly coveted by feather collectors and mages. It is said to add powerful properties to certain magical concoctions, brews and other magical devices. Only the most powerful of owlbears can grow a single golden feather, and that only once in a lifetime. A golden owlbear feather is a treasure, made of gold, and weighs 0 pounds 12 ounces.
