The Late Shift
It is generally a bad idea to look a vampire in the eye. They have a way of messing with your head that seems to rely on eye-contact.
Obviously, FPD agents have made a hobby of collecting vampire eyes. They seem to keep if you soak them in blood.
A vampire eye can be implanted into an operative. Results seem to vary . . . it seems that not all vampires are created equal.
Cost: 1 willpower/1 bashing damage
Benefit: VARIES (grants strange powers)
Drawback: The eye is EXTREMELY sensitive to sunlight!!!
