Moon Lord

Background

He spawns once the four Celestial Pillars are destroyed, or can be summoned with a Celestial Sigil in any world where Golem has been defeated. A countdown comes first, lasting 60 seconds after the pillars or 12 seconds with the Sigil, while the screen dims and the world shakes. The heart in his chest is the core that must be destroyed to win, but it only becomes vulnerable after the three eyes in his forehead and hands are destroyed, and each eye can only be hurt while it is open. A destroyed eye turns into an invulnerable True Eye of Cthulhu that keeps attacking until the fight is over. While he is alive, no enemies or critters spawn near players who are close to him.
