An eye killer is a creature with a bat-like upper torso on the body of a large snake. Its stunted wings cannot support flight. Its upper body is a dark grey-green while the lower part is a medium green flecked with dully yellow. Its eyes are disproportionately large and apparently lidless. An eye killer dwells in dark places underground. An eye killer will attack creatures by crushing them with its coils, but if an approaching party carries lanterns or torches, the eye killer can use its Death Stare once per day. Its eyes gather the illumination falling on them, amplifying it enormously, and project it back at the light-bearer as a powerful, narrow ray of intense light that kills instantly.
