If you wait for the Eye of Cthulhu in the middle of your arena, well equipped with ranged weapons and a bag full of healing potions, you have already drastically increased your chances of winning. In order not to be overwhelmed by the boss’s attacks now, you need to familiarize yourself with its attack patterns. The eye of Cthulhu has two combat phases in which it uses different strategies.

In the first phase, the boss will start hovering around you and summon three to four servants of Cthulhu. They will then attack you. Once you have defeated the servants, the Eye of Cthulhu itself becomes active and tries to ram you three times. The eye will aim exactly at your character and race towards him. After three ramming attacks, the cycle begins again with the summoning of the servants.

While the servants are flying towards you, you can shoot the eye with your ranged weapon to defeat the servants in melee. Alternatively, you can drop the servants with shuriken right after they spawn. Shuriken have the property that they fly through enemies and damage other enemies. So they can be perfectly used here to defeat the servants and at the same time cause damage to the eye itself.

For ramming attacks, you must try to dodge by jumping to a higher or lower platform of your arena. At the same time, you can fire at the eye rushing towards you to cause further damage.

If the Eye of Cthulhu has only half of its health left, a transformation occurs. The pupil disappears and in its place now gapes a large mouth armed with sharp teeth. In this second phase, the boss has no more defense, but it causes significantly more damage. The boss will only try to ram you, this time with higher frequency and more aggressively. So make sure that you always keep enough distance from him and switch often between the levels of your arena. At the same time, you can constantly attack with your ranged weapon to minimize your opponent’s life bar bit by bit.
