Amethyst broad bolts

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.

Fletching
They can be player made using the Fletching skill of at least level 76 by adding amethyst bolt tips to broad bolts after purchasing the ability to fletch them for 300 Slayer reward points.

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.
