Mithril bolts may be tipped with sapphire, emerald, or a grapple. To tip the bolts with sapphire, a player must have a Fletching level of 56 and use sapphire bolt tips with the mithril bolts, granting 4.7 Fletching experience for each sapphire bolt tip attached and making the mithril bolts into sapphire bolts. To tip the bolts with emerald, a player must have a Fletching level of 58 and use emerald bolt tips with the mithril bolts, granting 5.5 Fletching experience for each emerald bolt tip attached and making the mithril bolts into emerald bolts. To tip a bolt with a grapple, a player must use a mithril grapple tip on the mithril bolt, granting 11 Fletching experience, and also a rope, making a mithril grapple.
These bolts are commonly used for mid-level PvP and general monster killing and/or training, as they have proven to be cheap yet effective.
