Crossbow bolts are ammunition for the crossbow and the phoenix crossbow. These have about the same power as bronze or iron arrows. These are the second strongest bolts in RuneScape Classic, only beaten by oyster pearl bolts, which have power similar to mithril arrows.
Crossbow bolts cannot be made by players. Instead, they can be bought from several shops or picked up at a spawn point on the first floor of Grum's Gold Exchange in Port Sarim.
They can be made into oyster pearl bolts by using them with oyster pearl bolt tips, giving the player 6.25 Fletching xp per bolt.
