"Una amenaza ocular que solo aparece por la noche."
no debe confundirse con The Eye of Cthulhu, un Hardmode yoyo, o el True Eye of Cthulhu, un minion of the Moon Lord.

El Eye of Cthulhu es un pre-Hardmode boss. Este es uno de los primeros jefes que puede encontrar un jugador, ya que aparece automáticamente cuando se alcanza un nivel relativamente temprano de avance en el juego. También se puede invocar manualmente con el Suspicious Looking Eye por la noche (see Spawn below).

While the Eye of Cthulhu is alive, the music Jefe final 1 will play. When Otherworldly music is enabled, the track Boss 1 (Otherworldly) will play instead.

En el Versión de consola de antigua generación Versión de consola de antigua generación, Jefe final 5 sonará.


El Ojo de Cthulu se puede invocar manualmente usando un Suspicious Looking Eye por night (beginning at 7:30 PM in-game time).

También tiene una probabilidad de 33.33*1/3 (33.33%) de aparecer automáticamente cada noche, si se cumplen las siguientes condiciones:

  • El Ojo de Cthulhu no ha sido derrotado en el mundo actual.
  • Al menos un jugador en el mundo tiene al menos 200 como máximo health y mas de 10 defense.
  • Al menos cuatro town NPCs (including the Mercader ambulante y town pets) estan presentes en el mundo.

If spawning this way, its arrival is announced by the status message "Crees que una presencia maligna te está observando...". If the player is sufficiently far underground, the Eye of Cthulhu will not spawn until they return to the Surface. If they remain underground all night, the boss will not spawn at all.


The Eye of Cthulhu has two phases, and is able to fly through blocks in both of them. During the first, it attempts to float directly above the player, while spawning 3–4 Siervo de CthulhuServants of Cthulhu, which drop Hearts and Stars on death. A servant is spawned with the typical hit sound . Afterward, it charges at the player three times in succession, before repeating the cycle.

When the Eye of Cthulhu falls below 50% / 65% health (1400 / 2366 / 3016), it transforms into its second form (shedding its iris into a mouth), which rams the player more aggressively three times, then hangs in the air for a period. It no longer spawns Servants of Cthulhu, and has no defense, but now has increased contact damage. It now lets out a roar every time it charges.

In Modo Experto, the boss spawns more Servants of Cthulhu than normal, as well as 4–5 servants upon transforming. In the second phase, it will gain an additional powerful rapid chain dash attack, during which it lets out a higher-pitched roar every time it dashes. These dashes become faster as the Eye of Cthulhu's life decreases, and it can dash nearly continuously when close to death.

If Eye of Cthulhu is not defeated by dawn (4:30 AM), if all players die, or if it goes too far off-screen, it will despawn.


  • When spawning naturally, the Eye of Cthulhu spawns exactly 81 seconds after the status message has appeared.
    • Being in a layer lower than the surface at that moment, or, in single player, exiting the world during that timespan, will prevent the Eye of Cthulhu from spawning naturally.
      • Players will have to remain underground for most of the night to prevent the Eye of Cthulhu from spawning. Returning to the surface using a Magic Mirror before night ends will cause it to spawn as usual.
  • Only one Eye of Cthulhu can be summoned at a time. Nothing will happen if the summon item is used while the eye is still present or the time is unsuitable. However, if one uses the item after the natural spawn message appears but before that eye spawns, the second eye will still spawn.

For more elaborate strategies on defeating Ojo de Cthulhu, including weapon and arena recommendations, see Guide:Eye of Cthulhu strategies.
  • The Eye of Cthulhu drops either Demonite or Crimtane Ore. While the corresponding set of armor and a number of tools additionally require Shadow Scales or Tissue Samples respectively—which the Eye does not drop—the sword, bow, axe, yoyo, and fishing pole can be crafted with only the bars.
  • Due to the ease of crafting its summoning item and relatively low difficulty, farming the Eye of Cthulhu is one of the more effective ways of making money prior to Hardmode. It drops 3 / 750 up front, plus ores which can be sold as bars for twice (Demonite) or triple (Crimtane) that amount.
  • The Eye of Cthulhu will only spawn randomly if a player has more than 10 defense. Taking defense-boosting equipment off before dusk can prevent it from spawning randomly.
  • The boss looks at the player it will follow, which can be helpful information in multiplayer.
  • It is most vulnerable during its transformation, because it neither moves nor attacks. However, there is only a brief window of opportunity for this.
  • Because there are no location-based requirements for summoning, defeating multiple Eyes of Cthulhu in an area can be an effective setup for harder boss fights as the dropped Hearts can be picked up mid-fight as needed, though killing an Eye of Cthulhu for that purpose must be balanced with the time it takes away from killing a night-only boss.
  • While it may seem that killing it on a Corruption-generated world would yield more money than doing so in a Crimson-generated world, as it will drop additional Unholy Arrows, Crimtane Ore and Bars sell for a 30% higher price than their Demonite counterparts, making them much more profitable.
  • In singleplayer, the player can repeatedly pause the game using Autopause in order to properly aim at the Eye of Cthulhu during its dash attacks.


  • The Eye of Cthulhu, among several other bosses, is based on Cthulhu, a creature first imagined by American author H. P. Lovecraft in his short story "The Call of Cthulhu".
  • The existence of the Auténtico ojo de Cthulhu, an entity spawned by the Moon Lord (who bears resemblance to Cthulhu), may imply that the Eye of Cthulhu is not Cthulhu's actual true eye.
    • This was later overturned by retcons from official game lore and Bestiary entry, both of which confirm it was actually separated from Cthulhu.
  • Assuming that the player is at 5′ 9½″ (1.75 m) in terms of height, the Eye of Cthulhu would be about 13′ (4 m) tall and wide in its first form. The teeth would be 2.6′ (0.8 m) long.
  • The Merchant NPC will mention sensing an evil presence watching him once the requirements to battle the Eye of Cthulhu are met.
  • Although irrelevant to game progression, the Eye of Cthulhu will keep spawning naturally until defeated at least once.
  • It is possible to defeat the Eye of Cthulhu without it ever transforming into its second form, e.g. with late-game weapons or Heart Arrow. However, its gore will be unaffected once killed.
  • The Eye of Cthulhu Trophy is a tooth of Eye of Cthulhu, which is only physically seen in its second form.
  • The Eye of Cthulhu seems to have central heterochromia iridum, an eye condition where there are two colors in the same iris.
  • It was one of the first bosses added, debuting in update 1.0.
  • The Eye of Cthulhu is sometimes abbreviated as "EoC".
  • If the player is using an RGB-keyboard, a mini Eye of Cthulhu can be seen dashing from the left to the right during the battle.
  • The Eye of Cthulhu can sometimes be seen flying in the background as ambiance at night.
    • Two clouds shaped like the Eye of Cthulhu's first and second forms can also appear in the background.
  • The Eye of Cthulhu appears in 2 games from a crossover event: Dungeon Defenders 2 as a boss and in Don't Starve Together, under the name "Eye of Terror" instead.
  • The Eye Of Cthulhu appears in day instead of night in some artwork for Terraria. This is most seen in the PS3 Cover & The Xbox 360 Cover.
  • The BestiarioBestiario entry for the Ojo de Cthulhu: "Este es un pedazo de Cthulhu, arrancado de su propio cuerpo hace siglos en una cruenta guerra. Vaga por las noches buscando un cuerpo que le haga de anfitrión... ¡y ansioso de vengarse!"
