Amethyst broad bolts are enhanced broad-tipped bolts. They require a Slayer level of at least 65 and a Ranged level of at least 61 to equip. They can be fired only by the runite, dragon hunter, dragon and Armadyl crossbows.
With a Ranged Strength bonus of +115, they are the equivalent of runite bolts in combat. Amethyst broad bolts are a superior alternative to their regular and arrow equivalents for the purpose of slaying Turoth and Kurasks using ranged.
Broad bolts are fletched 10 at a time and give 10.6 Fletching experience per bolt, or 106 experience per set of 10 bolts made.
