Broad arrowheads

Broad arrowheads can be made into broad arrows (by combining them with a headless arrow) using the Fletching skill after completing the Smoking Kills quest. The finished arrows are used in the Slayer skill to kill kurasks and turoths. The crossbow equivalent of these are unfinished broad bolts. Kurasks drop broad arrowheads, up to 57 at a time. After Smoking Kills, they can also be purchased from any Slayer Master for 50 coins each, and from Turael/Spria or Jacquelyn Manslaughter, who hold a separate stock between them. Fletching broad arrows gives 15 experience each, or 225 experience per set of 15 with a loss of 0 coins. Broad Arrows are more powerful than rune arrows (and slightly less powerful than dragon arrows) but are untradeable. You can buy the ability to fletch these with Slayer Reward Points, from completing several tasks.

Broad arrowheads are also a very fast way of training your Fletching. By getting the arrowheads and making them into full arrows you can gain up to 675,000 experience an hour. The downside to this is that they cannot be sold once made, resulting in a large loss of money (up to 6M per hour).

Broad arrowheads are also an excellent method for training fletching on ironman accounts. Players can buy 6,000 broad arrowheads per day (3,000 from Turael and 3,000 from any other slayer master) which is equal to 90,000 experience per day at a cost of only 300k gp. This offers a much faster xp/hr method than the commonly used method of gathering maple logs from miscellania. Note: In order for this method to be viable, you must still collect maple logs from Miscellania to use for arrow shafts and you must also buy feathers from shops (8,000+ per day).

Since the "Fletch-x" update on bolts, broad arrows are now considered to be the fastest affordable fletching xp, with the cost of dragon arrows and darts being unreasonable for most.
