Mythril armor

Mythril armor is an armor which requires Mythril Bars and must be crafted at a Mythril Anvil. Like all Hardmode ore armors, Mythril armor has three different headgear/helmet options, allowing players to focus on magical, melee or ranged combat, and each changing the set bonus. Crafting a one-helmet set requires 45 Mythril Bars or 180 Mythril Ore. Crafting all five pieces requires 65 Mythril Bars or 260 Mythril Ore.

Trivia
The mythril chainmail could be a reference to the Lord of the Rings, where the main character has a chainmail made of mythril, "the strongest metal in the world".
