Potenteye is an innate ability which Sapes may rarely be born with. This ability allows a sape to visually perceive the direction, rate, and size of a flow of magic.

This ability differs from the more powerful Magic Sight of a dragon in that skilled sapes may conceal the flow of their magic from other potenteye users. Additionally, potenteye requires some effort to activate and maintain, whereas magic sight requires no effort on the part of the dragon and may be activated or deactivated at will.
