Third Dynasty: Eye of Horus

Unlike most of Fa' raos known jutsu this one allows Fa' rao to see the chakra of his opponent and its nature during thier attack, what makes thie eye so unique is that it can see the cells in the body and can even tell the difference between clone and the real one. With this eye active in battle any genjutsu used on him the damages is immediately inflicted back to the user as the eye can read the chakra and sever the link. He will still the images of the genjutsu but the mental damage it causes will be directed back toward the Caster. This jutsu can effectively warn him of impending danger of an jutsu as well as where it is at its strongest and its weakest

Fa' rao developed this jutsu to deal with the Rinnegan of the Sage and the Unique eye of the Juubi
