Orichalcum Ore is a magenta-colored Hardmode ore which can replace Mythril Ore in a given world. It requires a pickaxe power of 110% to mine (Cobalt/Palladium Pickaxe or better, or any drill). Like most Hardmode ores, Orichalcum Ore is generated upon destruction of a Demon/Crimson Altar with a Pwnhammer or any better hammer.
- On a small map, Orichalcum spawns below a depth of 1,000 feet (500 tiles).
- On a medium map, Orichalcum spawns below a depth of 1,400 feet (700 tiles).
- On a large map, Orichalcum spawns below a depth of 2,000 feet (1,000 tiles).
- The advantage Orichalcum has over Mythril is its unique color. Mythril Ore does not stand out as much and bears resemblance to other ores and blocks.
- In real life, orichalcum is a legendary metal described by the Athenian philosopher Plato in his work Critias to have been mined in the lost city of Atlantis. It is suspected to have been a sort of alloy involving copper.
- While the in-game color is magenta, orichalcum is speculated to be a more reddish hue.
