Wandering Eye

Wandering Eyes are Hardmode only enemies that act similar to both Demon Eyes and Eye of Cthulhu. They will attack like Demon Eyes until they reach half health, then their pupils will turn into fangs much like Eye of Cthulhu, adding speed and damage. And much like Demon Eyes as well, they only spawn at Night and will flee when the sun rises. Unlike the Demon Eye, the Wandering Eye doesn't drop Lenses.

Wandering Eyes appear more often during a new moon.
