Demon Eye

The Demon Eye is a basic flying enemy that appears at night. Its trajectory is changed when hit with knockback. The Demon Eye drops coins, and occasionally a Lens or Black Lens, when killed. It has a slow turn rate, follows the player, and bounces off blocks. It uses Flying AI.

When killed a Demon Eye will commonly drop a lens. If your mana is not at full capacity it'll also occasionally drop a Mana Crystal.
