Opal bolts

Opal bolts are bronze bolts tipped with opal. Opal bolts can be created through the Fletching skill. A player must have a Fletching level of 11 and take a cut Opal and use a chisel with it to make 12 Opal bolt tips, granting 1 Fletching experience. Attaching opal bolt tips also requires a Fletching level of 11, and for each opal bolt tip attached to a bronze bolt, a player is granted 1.6 Fletching experience. Once the opal bolt tips have been attached, the bronze bolts become opal bolts.

Opal bolts can be enchanted through the spell Enchant Crossbow Bolt (Opal) by a player with level 4 Magic. The spell enchants 10 opal bolts at a time, and once they are enchanted they become enchanted opal bolts and gain a special ability.
