Orichalcum armor

Orichalcum Armor is a hardmode armor and is ultimately crafted from ore that can spawn in place of Mythril Ore. Its stats are similar to those of Mythril armor and can therefore be seen as a direct replacement.

Mechanics
Whenever you strike an enemy a Flower petal spawns at the edge of your screen and shoots to the other end of your screen. The Flower petal will always hit the enemy you hit, however it can hit any other enemy that it goes through. The Flower petal deals approximately 18-25 damage to each target it strikes. A flower petal is also spawned when you hit a projectile that can be destroyed when hit. The Flower Petal appears roughly once per second, provided that there is a source of continuous damage.

Trivia

 * This armor appears to be very 'girly', because of pink color and set bonus.
