Guide:Eye of Cthulhu strategies

Terrain and Gear


Like all Bosses, preparing for the fight is probably the biggest factor in your success:

When fighting the Eye of Cthulhu, a strategy I've always found to work is to make an arena of Dirt Block or Stone Block and place wood platforms every 6 blocks so that you can evade the Eye by either running, jumping or dropping.

Good Armor is recommended for this fight, because even though the boss doesn't hit very hard, he summons a lot of Servant of Cthulhu and can be rather hard to dodge for the new/inexperienced player.

Weapons
Because of all the servants this boss summons, weapons with a piercing attack are extremely useful. An effective weapon to take are shurikens, a stack or two is more than enough to defeat this boss with relative ease, other weapons to take would be a Bows with Flaming Arrows/Unholy Arrows for the high damage. If you have the money to spare, grenades can be used. Because the boss is a flying type, melee weapons are limited in use.

First Phase
During this phase, the Eye will, for a large majority of the fight, float around above you, summoning Servants to fly towards you and kill you. A good strategy in this phase is to aim ranged weapons at the pupil of his eye, since that is where he spawns the Servants. That way, you can kill the servant and damage the eye.

Second Phase
For the last half of the fight, the boss turns into a massive, flying, eye-mouth... Thing... It'll charge you 3 times, and then wait a few seconds during which you can nuke him.

Death
Fail to kill the Eye of Cthuhlu and he despawns.
