Buy RS3 Mithril crossbow
The mithril crossbow is a ranged weapon in RuneScape 3. It needs level 30 Ranged to wield, and it is free to play. It is stronger than the black crossbow but weaker than the adamant crossbow. It uses bolts as ammo.
This is a tier 30 weapon with 454 accuracy, 288 ability damage, and a range of 7. It attacks at the fastest speed, which is 2.4 seconds. It weighs 2 kg and can be traded or noted.
The mithril crossbow is also useful outside of combat. You need one to build the hidey-hole shortcuts at Musa Point and on Water Obelisk Island. You can pair it with a mithril grapple to use grapple rocks at Catherby and Karamja, or to make an enhanced grappling hook.
Players can also disassemble it for Invention parts. It gives 8 materials per crossbow, with a chance at connector parts, tensile parts, spiked parts, stunning components, and dextrous components. This makes it handy for gathering parts as well as fighting. It is a solid pick for low level rangers and for anyone working on shortcuts or Invention.
