Dragon dart tips are used in the making of dragon darts. At level 95 Fletching, they can be made into dragon darts by adding feathers. Fletching a set of 10 will provide 250 experience (10 darts per action).
In theory, it is possible to get up to 13,500,000 experience per hour fletching dragon darts. Doing this in practice is impossible without third-party software, as it requires nine sets to be fletched every 0.6 seconds, and one can expect to get up to 3-4 per tick by hand. Nonetheless, dragon darts are the fastest method of training Fletching, although due to their price and limited supply, this is usually nonviable for long-term training.
