Arrow of Slaying (Dragons)

A single arrow in a lacquered case, the head etched with a coiled wyrm and the shaft inscribed in a language Polities says ‘nobody alive speaks politely.’ Meant for dragons, specifically. A hit forces a DC 17 Constitution save — six dice on a fail, three on a success, on top of the arrow’s normal damage. One shot, then it’s a regular arrow. A rumor, a hedge, and a family heirloom, all in one shaft.
