EX Orbs (EXオーブ, ekusu oobu), also known as Ancient Orbs (古の宝珠, inishie no houshu), are orbs that can be inserted in the core of a Divine Knight to enhance its basic parameters. Ancient technology, like the tool found by Clara in the Ancient Quarry in Sen no Kiseki II, is required to create EX Orbs. Valimar is the only known Divine Knight to support this technology and can hold up to three EX Orbs at the same time.
