Mythril Ore is a Hardmode ore that appears in the world every two out of three Demon Altars or Crimson Altars (note that its equivalent, Orichalcum Ore, may spawn instead) that have been destroyed.
Mythril Ore is found throughout the Cavern layer. It can only be mined by a Cobalt Drill/Cobalt Pickaxe or higher. To craft all Mythril equipment, the player needs to acquire 155 bars, or a total of 620 ore.
