The Eye of Cthulhu is a pre-Hardmode boss. It is one of the first bosses a player may encounter, as it spawns automatically when a relatively early level of game advancement is achieved. It can also be summoned manually with the Suspicious Looking Eye at night (see Spawn below). 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 Servant of 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 (1,400 / 2,366 / 3,016), 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.
