Pericog

A technique that is simple in theory and difficult in practice. Using the principles inherent in the Basic Clone Technique (mostly those that relate to the manipulation of light), the user refracts light with her chakra and guides them into her eyes. This allows the user to see in all directions and even around bends, however, as the user is presumed to be constantly moving, the user of Pericog must also constantly change the areas and degrees of refraction to accommodate her new positions. This makes Pericog a technique that is near impossible to use in combat.

In fact, the most common use of Pericog is instead for scouting. Pericog also allows the user to refract light in such a way so as to enlarge and minimize a visual image, allowing one to observe targets so long as the user is capable to sending chakra to the area to capture its light.
