Bane Nut

This hollowed out walnut shell has been crafted into a mini poisoners kit. It includes three poisons of your choice, a tiny funnel and is guilded for elegance and function. The inventor of this little item was an assassin that went by the name of Quick. He would carry two poisons and one perfume at all times boasting that he was always prepared to be a killer with the ladies. He poisoned himself by confusing the three vials.
But his legacy endures through this handy little 'Bane Nut'. It was lifted off his body by a fellow underworld figure who had the sense to patent the item and sell the legal rights to a craftsman. Of the two untoward fellows that were responsible for bringing this item to you it is the smarter one whose name had been forgotten.
