Raptor Arrow

Legend says these arrows (there are reputedly five) gained relic status when Ehlonna used them to slay a great wyrm green dragon that was rampaging through a forest primeval. A raptor arrow is a +3 arrow with a variant of the returning quality. At the beginning of the round after it is fired from a bow, a raptor arrow wrenches itself from whatever it hit (dealing 1d8 points of damage), flies up to 400 feet through the air, and restrings itself in the bow from which it was fired. Unlike most ammunition, raptor arrows are never destroyed when they hit their target.
If a ranger fires a raptor arrow at a favored enemy, the arrow additionally gains the bane quality against that foe.
