Demon Eye

The Demon Eye is a common flying enemy that appears on most Surface biomes during the night. It has a slow turn rate, follows the player, and bounces off blocks. Its trajectory is changed when hit with a weapon that causes knockback.

Variants
There are fourteen variants of the Demon Eye, all of which have the same drops and drop chances.

Tips

 * Demon Eyes attempt to fly straight towards the player, and when they hit a wall, they bounce up. This allows for relatively easy escape by hiding behind a wall with a upside-down L shape.
 * Due to the fact they cannot enter water, they cannot reach the player if they are completely submerged. However, they can still hit them with their broadsword or any ranged weapon.
 * New players may find that spear-type weapons are quite effective against these enemies.
 * It is also recommended to use ranged weapons, such as the Wooden Bow, when dealing with Demon Eyes, as they spend much of their time out of reach. The best time to attack it is when the Demon Eye is turning, as a successful hit will knock it back and interrupt its flight pattern, allowing the player to get in more shots before it reaches them.
 * One can avoid damage from Demon Eyes entirely by using said bow while within a box with a 1 wide hole. This is enough space to allow proectiles through, but not Demon Eyes.
 * If the player swings in a different direction each time with their sword, they can effectively trap a Demon Eye with knockback in their sword's range, as the sword will knock it in the way the player is facing.

Trivia

 * The Eye of Cthulhu, Servant of Cthulhu, and Wandering Eye are modeled after this enemy.
 * The Cataract Eye takes reference to the real-life eye condition known as both in sprite and name, hence the cloudy lens.
 * The Sleepy Eye resembles the Monoeyes from the Kid Icarus series.
 * A sprite based off the Demon Eye served as the loading icon of the after Mobile 1.2.12715's release and before Mobile 1.3.0.7's release.
 * Demon Eyes appear in the video game Dungeon Defenders 2 as enemies.
 * According to the Bestiary, Demon Eyes can become erratic during a Blood Moon and twist together into a cluster of blood and eyeballs, creating a Drippler.
