Buy OSRS Mithril dart
The Mithril dart is a Ranged throwing weapon in Old School RuneScape. It is a members-only item. You need level 20 Ranged to wield it. Each dart has a Ranged Strength bonus of +9 and weighs nothing. Darts are stackable, so you can carry thousands in one inventory slot.
Mithril darts are one of the most cost-effective Ranged training weapons for lower level players. They attack very fast. On the Rapid style they fire every 1.2 seconds. This quick rate of fire makes them great for building Ranged experience. They also work with one-handed setups, so you can wield a shield or god book at the same time for extra protection.
These darts can be poisoned to deal extra damage over time. Their range is 3 tiles on Accurate and Rapid styles, and 5 tiles on Longrange.
Players can also make mithril darts in the game. This needs the Tourist Trap quest, level 54 Smithing, and level 52 Fletching. Each mithril bar makes 10 dart tips, and feathers are added to finish the darts. Buying them ready to use saves that effort and gets you training right away.
