How To Summon Eye Of Cthulhu

What Is The Eye Of Cthulhu

The Eye of Cthulhu is one of the earliest bosses players encounter in Terraria, providing a significant challenge for beginners. This massive, floating eye monster has a two-phase battle:

• Phase One: The Eye hovers and charges at the player in a semi-predictable pattern. It periodically spawns Servants of Cthulhu, small enemies that can be defeated for minor loot and to reduce distractions.
• Phase Two: Once its health is halved, the Eye sheds its pupil, revealing a sharp-toothed mouth. In this phase, it becomes more aggressive, charging rapidly at the player, making movement and dodging critical to survival.

Notable Drops:

• Demonite Ore or Crimtane Ore (used for crafting powerful pre-Hardmode weapons and armor)
• Unholy Arrows (effective early-game ammunition)
• Corrupt Seeds or Crimson Seeds (spreads Corruption or Crimson in your world)
• Shield of Cthulhu (grants a dash ability and adds mobility in combat)
• Eyemaster’s Aviators
• Eye of Cthulhu Mask and Trophy
• Coins and other miscellaneous loot

How To The Summon Eye Of Cthulhu

Suspicious Looking Eye Method

The most reliable way to summon the Eye of Cthulhu is by crafting and using a Suspicious Looking Eye. This method allows you to summon the boss at your convenience, provided it is nighttime. Here's how to prepare and execute this method:

Required Materials:

• 6 Lenses: Dropped by Demon Eyes at night.
• Crafting Station: A Demon or Crimson Altar.

Craft the Suspicious Looking Eye at an altar and use it at night on the surface to summon the boss. Note, that the Eye of Cthulhu cannot be summoned or fought during the day. If the battle extends into daytime, the boss will despawn immediately, so time management is crucial when engaging this fight.

Natural Spawn Method

The Eye of Cthulhu may spawn automatically at night under these conditions:

• The boss hasn’t been defeated in the current world.
• At least one player has 200 maximum health and 10 or more defense.
• At least four NPCs (including pets or the Traveling Merchant) reside in the world.

If these conditions are met, you’ll see the message, “You feel an evil presence watching you…”, indicating that the Eye of Cthulhu is about to spawn and the fight will soon begin. If you stay underground at night, the Eye of Cthulhu won’t spawn, as it requires players to be on the surface.
