Orichalcum Armor is a Hardmode armor set and is the counterpart to Mythril Armor. Like all Hardmode ore armors, Orichalcum armor has three different headwear options, allowing players to focus on magical, melee, or ranged combat, and each with a corresponding set bonus. Crafting a one-helmet set requires 54 Orichalcum Bars or 216 Orichalcum Ore. Crafting all five pieces requires 78 Orichalcum Bars or 312 Orichalcum Ore.
Whenever the player strikes an enemy while wearing a full set, a flower petal is summoned at the edge of the screen and shoots to the other end of the screen. The flower petal will always be aimed at the enemy that triggered it, but it will damage any other enemy that it goes through. The flower petal deals around 30 damage to each target it strikes and can pierce, causing damage to multiple foes in a line with a single attack. Petals travel very quickly and pass through solid blocks and liquid with ease. There is roughly a one-second cooldown before another flower petal can be summoned again.
- The flower petals will destroy pots, grass, etc, which can also lead to summoning the Queen Bee by accidentally destroying the Larva inside a Bee Hive.
- The flower petals can be triggered by Minion attacks.
- if you have a star cloak, the stars caused from being attacked will cause flower petals.
- This is very effective with The Horseman's Blade due to the attack making both petals and pumpkins.
- To color-match items to Orichalcum armor, use Violet Dye as opposed to Pink Dye.
- The Orichalcum armor's set bonus is powerful against worm-type enemies like the The Destroyer or the Wyvern, as a well-aimed petal will hit all of their segments.
- Orichalcum is a metal mentioned in ancient writings, but its nature and means of creation is lost to history, leaving it known only by name. It is frequently used in fantasy works as a material more valuable than real-world metals, but there is little consistency between its properties in popular culture.
