Emerald bolts can be created through the Fletchingskill. A player must first have a Fletching level of 58 and take a cut emerald and use a chisel with it to make 12 emerald bolt tips. The emerald bolt tips can then be attached to mithril bolts to make emerald bolts. Attaching 10 emerald bolt tips to 10 mithril bolts grants 55 Fletching experience. Note that these bolts require a crossbow of level 60 to fire.
