Afterward, the head eye blinks a couple times, fires two Phantasmal Bolts again, and then closes. This is by far the Moon Lord's most damaging attack, and it can pass through solid blocks that block it from the player. The sweep direction depends on the location of the target: if the target is to the left of the Moon Lord, it sweeps clockwise, otherwise, it sweeps counter-clockwise.

When Otherworldly music is enabled, the track Lunar Boss (Otherworldly) (Otherworldly).mp3 will play instead. While Moon Lord is alive, his exclusive music Moon Lord will play.

If using a Celestial Sigil to summon the Moon Lord, it takes 12 seconds for the Moon Lord to spawn, and the screen effect will only appear once. If Moon Lord is spawned by destroying Celestial Pillars, it takes 60 seconds for the Moon Lord to spawn, and the screen effect will appear 5 times each time the screen will go darker and all objects and walls will oscillate more violently. During the countdown, the screen will go dim and all objects and walls will oscillate back and forth, and then go back to normal, and the sound volume will gradually decrease, eventually becoming completely silent. The status message " Impending doom approaches." indicates the Moon Lord's spawning countdown.

Moon Lord can be spawned by destroying the four Celestial Pillars or by using a Celestial Sigil in any world where Golem has been defeated. He is the final boss of the Desktop, Console, and Mobile versions of Terraria. Moon Lord is a Hardmode, post- Lunatic Cultist boss.
