How to summon Moon Lord

Celestial Sigil. Destroy all four Celestial Pillars, or use a Celestial Sigil after Golem is beaten. The sigil is crafted from 12 each of Solar, Vortex, Nebula and Stardust Fragments at the Ancient Manipulator.

Attacks and phases

His two hand eyes and head eye open and close; you can only hit them while open.
The hands fire Phantasmal Spheres, homing Phantasmal Eyes and bolts; the head fires a huge Phantasmal Deathray.
Destroyed eyes become True Eyes of Cthulhu that keep attacking.
Once all eyes are gone, the chest core is exposed and must be destroyed.

Strategy

Build a very long sky bridge with Campfires and Heart Lanterns along it.
Keep moving to the side. Phantasmal Eyes can't track upward well, so jumping helps.
Watch the head: when the Deathray charges, move away and keep going.
His tongue grabs close players and gives Moon Bite, which blocks life steal.
Use the best potions you have, plus Well Fed, and the best pre-lunar armor: Beetle, Shroomite, Spectre or Spooky.
