Onyx bolts

Onyx bolts are Rune bolts tipped with Onyx bolt tips. Onyx bolts can be created through the Fletching skill. A player must first have a Fletching level of 73 and take a cut Onyx and use a chisel with it to make 24 Onyx bolt tips, or buy the Onyx Bolt Tips from the Tzhaar. NOTE: It is advised not to cut an Onyx into bolt tips, since a cut Onyx is worth millions more than 24 tips. Attaching Onyx bolt tips also requires a Fletching level of 73. Once the Onyx bolt tips have been attached, the Rune bolts become Onyx bolts.

Onyx bolts can be enchanted through the spell Enchant Crossbow Bolt (Onyx) by a player with level 87 Magic. The spell enchants 10 Onyx bolts at a time, and once they are enchanted they become Enchanted onyx bolts and gain a special ability.

Two or four may be looted from a Ninja impling. Up to 53 bolts can be looted from a Kingly Impling. Elite Treasure Trails may also feature 30 onyx bolt tips as a reward.
