The mithril dart tip is a dart tip made with the Smithing skill. Players can craft this item when using a mithril bar on an anvil with a hammer in the inventory and a Smithing level of 54. Each bar makes 10 mithril dart tips, yielding 50 experience. They can be fletched into mithril darts at level 52 Fletching when used with feathers, granting 112 Fletching experience per 10 darts made.
To smith darts, one must have started the Tourist Trap quest to the point where you return to the Bedabin Camp with the weapon plans.
