Mythril Bars are a type of Hardmode-bars made from Mythril Ore. They are necessary to make the Mythril Anvil, which in turn is needed to make most end-game equipment. The Mythril Drill and Mythril Pickaxe are the first tools acquired that are capable of harvesting all but two block types in the game (exceptions being Chlorophyte Ore and Lihzahrd Bricks).
- Mythril Bars can be found within Wooden, Iron, and Golden Crates during hardmode without the need of a drill or pickaxe.
- Mithril is a fictional metal in J.R.R. Tolkien's Middle Earth writings, where it is a rare and high-quality material used for weapons and armor. It has become a widely used material in fantasy works, particularly video games.
