Onyx bolts

Onyx bolts are runite bolts tipped with onyx. A player must first have a Crafting level of 67 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. 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.

Elite Treasure Trails may also feature 12 onyx bolt tips as a reward. Ninja implings can be looted for 4 tips or 2 bolts. Up to 73 tips or 57 bolts can be looted from a kingly impling. The rare drop table may also drop these in stacks of 150 at a time.
