Elder arrow shafts are used to create black stone arrows through the Fletching skill. Elder arrow shafts can only be cut from elder logs at 90 Fletching by using a knife on them. 15 feathers can be attached to 15 elder arrow shafts at 90 Fletching, granting 15 experience, to make elder headless arrows. Black stone arrow tips cannot be attached to elder arrow shafts without feathers.
