Eye of Cthulhu

. The Eye of Cthulhu is a Boss monster that the player can fight. It can be summoned by using a Suspicious Looking Eye which is crafted at a Demon Altar. In order to summon the boss, it must be night; otherwise, nothing will happen.

It is also possible for it to spawn soon after the message "You feel an evil presence watching you" appears. This happens when the player has at least ten hearts (200 life), more than 10 defense, hasn't defeated the Eye of Cthulhu before, and has at least 3 NPCs. When these conditions have been filled, each night the Eye of Cthulhu has a 1 in 3 chance of showing up.

This boss has been described as the easiest by the game's developers.

Behavior
The Eye of Cthulhu looks like an enormous Demon Eye, but it behaves much differently. During the first stage of the fight, it alternates between hovering overhead and trying to ram the player. When hovering, the Eye will spawn Servants of Cthulhu. If the player remains still at this time, the Eye will position itself directly overhead. When ramming, it will charge at the player 3 times, often going through walls and diving underground.

After the Eye loses 1400 health, it will transform into its second stage. In this form, the Eye of Cthulhu is faster and deals more damage, but has lower defense and no longer spawns Servants of Cthulhu. It will charge at the player 3 times, then pause for a moment and hover overhead before repeating.

It is worth noting that the Eye of Cthulhu, while it drops Demonite Ore, will not drop Shadow Scales. Some Demonite items (such as Shadow Armor and the Nightmare Pickaxe) cannot be crafted without Shadow Scales. Shadow Scales are dropped by the Eater of Worlds.
