Runite limbs

Runite limbs are required to make a rune crossbow. They can be smithed from a rune bar at Smithing level 91, granting 75 experience. Rune crossbow limbs can be attached to a yew stock at Fletching level 69, granting 100 experience, to make an unstrung rune crossbow.They are a common drop from Metal dragons and Aviansie.

Note that the High Alch value of the complete crossbow is only 120 coins more than the limbs alone. It is more economically sound to use the yew log for a yew long and alch it rather than use it on a rune crossbow.
