Bone bolts

Bone bolts can be bought from the Nardok's Bone Weapons shop- run by Nardok in the Dorgeshuun Mines- after completing The Lost Tribe quest. Bone bolts cannot be fletched by a player. Bone bolts are usable only with the Dorgeshuun crossbow or Zanik's crossbow.

Bone bolts, along with a Dorgeshuun or Zanik's crossbow, are a cost-effective range training method, as Nardok sells the bolts for only 4 coins each. At the Grand Exchange bone bolts sometimes sell for as low as 2 coins each. This low price is why players training Ranged consider them popular to train with.

Curiously, the bolts can also be picked up by Ava's accumulator from the quest Animal Magnetism.
