Exorcist Eye

Exorcist Eye (エクソシストアイ Ekusoshisutoai) is a subspecies of Eye Magic that is used by Devil Slayers to combat demons. This particular subspecies can only be obtained via a random mutation that is triggered during the magical processes of becoming a Devil Slayer.

Description
Exorcist Eye's true power lies in its ability to sense demons from miles away, not only that, but, it can also scrutinize the demon's fighting style to try to find any weaknesses or flaws that can be exploited. This type of Eye Magic is usually very vital in defeating more powerful demons, atleast in Heath's case. Some etherious have described the effects of it as a "churning feeling in your stomach, as if you were looking down some high-up cliff."

The eye's take the shape of a completely blackened sclera with two crimson irises. Through extended use over long periods of time, strange markings resembling cracks begin to form around the user's eyes. These cracks grow worse as time goes on which usually can give the user a good idea on the strain of this magic.
