Oyster pearl bolts are ammunition for the crossbow and the phoenix crossbow. They are stronger than regular crossbow bolts, having power similar to that of mithril arrows. Unlike regular crossbow bolts, they cannot be poisoned. Oyster pearl bolts are created at level 34 Fletching by attaching oyster pearl bolt tips to regular crossbow bolts, yielding 6.25 experience per bolt.
