Opal bolts

Opal bolts are bronze bolts tipped with opal bolt tips and enhanced via Magic. Opal bolts can be created through the fletching skill for players of level 11 or above. Use a chisel on a cut opal 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, known as "Lucky Lightning". This enchantment causes extra damage to the opponent by hitting them with lightning.
