Persona 5 Royal
"A metal mentioned in ancient Greek literature. Some accounts say it was merely brass, but other stories suggest it was, in fact, a legendary material."
Orichalcum is the eighth Persona of the Faith Arcana, and a Treasure Demon found in Maruki's Palace, and happens to be the only Treasure Demon not introduced in Persona 5. It is strong against Physical and Gun skills, but weak against damage dealing Bless skills. When itemized by Electric Chair execution within the Velvet Room, it offers the Orichalcum accessory, which has an Evade Phys effect and raises all stats of its wearer by 6, but when itemized while the fusion alarm is sounding, Orichalcum offers the Orichalcum R accessory, a slightly stronger version that, while retains the Evade Phys effect, raises all stats by 7.
