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 attached to Moon Lord's head, the head eye opens every 20–21 seconds for a few seconds, fires two Phantasmal Bolts (similarly to those of the hands), and then fires a Phantasmal Deathray: a large laser that sweeps 60 degrees upward over the player.Another viable option is to quickly drop down before the bolts fire, saving the player from getting hit. The hand eyes also occasionally fire two Phantasmal Bolts in quick succession, aiming at the player, which pass through blocks, requiring swerves to avoid.They explode upon contact with a block or player. If they cannot get a direct lock and a player is in range then they will attempt to match the target's trajectory to stay in their path.

Like the Phantasmal Spheres, they cannot travel at an upward angle, so they can be evaded by swerving upwards. The hand eyes also spawn multiple Phantasmal Eyes, which move in all directions for a short while before homing in on the player.If the player is far enough away, they simultaneously charge at the player before exploding, though they cannot travel at an angle higher than approximately 30 degrees in any direction. After a couple of seconds, they explode, dealing heavy damage. Moon Lord's hands move away from the core and their eyes spawn six Phantasmal Spheres.The Moon Lord in battle firing his Phantasmal Deathray.

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.
