To achieve the higher classes of armor, forging two armor sets of the class beneath the current class are required. For example: Two Normal Armors forge to create one Rare Armor Piece, Two Rare Armor Pieces forge to create one Unique Armor Piece. Ancient Armors do not follow the rule. To forge an Ancient armor, you need a Unique Armor Piece and an Option Item. NOTE: Each races Physical and Magical base defense per Armor set differs from each others.
