Dragon darts are member's only Ranged throwing weapons. To wield them player must have at least 60 Ranged. They can be obtained by the Impetuous Impulses minigame, trading with another player or by fletching. Fletching dragon darts requires level 95 Fletching. They are fletched by adding feathers to Dragon dart tips, which are obtained by looting Dragon impling jars. Fletching a set of 10 darts gives 250 experience.

They, along with the Dragon Arrows, are technically not like other Dragon equipment in that they are not made from dragon metal and are therefore not red in colour. Rather, they are made from a dragon's talons. Dragon darts are the only dragon weapon not to have a special attack.

Dragon darts are often used by pures in PVP worlds as they hit 2 times a turn and take moderate damage; a good way to pk with them is to throw three darts and change to a more powerful weapon such as a 2-Hander or Dark bow.
