Prior to the Evolution of Combat, bone bolts, along with a Dorgeshuun or Zanik's crossbow, were a cost-effective Ranged training method. Nardok sells the bolts for 4 to 5 coins each, depending on the shop's current stock, but only sells a maximum of 300 at a time. It takes about a day for the shop's supply to completely restock. They were considered popular to train with amongst players training Ranged because of this low price, but this is obsolete due to the low rate of loss of ammo after the EoC. Nevertheless, they remain a good choice for low level players, especially those in Ironman Mode as making metal bolts from scratch may be time consuming and requires Mining, Smithing and Fletching levels.
