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.


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

  • Like Zombies, Demon Eyes sometimes spawn as either larger or smaller than normal; larger Demon Eyes have more health, damage, defense, and knockback resistance, while smaller Demon Eyes are faster and harder to hit.
  • Demon Eyes appear more often during a new moon.
  • Although the Dilated Eye variant appears to have a large, black pupil, its drop rate for Black Lenses are not guaranteed nor raised.


  • 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.
