Moon Lord Trophy"Impending doom approaches..."Moon Lord Trophy

The Moon Lord is a Hardmode, post-Lunatic Cultist boss. He is considered the final boss of the PC version PC, Console version Console, Mobile version Mobile, Old Chinese version Old Chinese, tModLoader version tModLoader, and tModLoader 1 tModLoader Legacy versions of Terraria.

The Moon Lord can be spawned by destroying all four Celestial Pillars or by using a Celestial Sigil in any world where Golem has been defeated. In both cases, he will then spawn one minute after the message "Impending doom approaches..." appears.

See below for the Moon Bite debuff inflicted by Moon Lord.

While the Moon Lord is alive, his exclusive Music will play.

Quick Answers

What is the Moon Lord's role in the game Terraria? toggle section
The Moon Lord plays a significant role in Terraria as the final boss of the game. This formidable adversary is summoned either by using a Celestial Sigil or by defeating the Celestial Pillars. The Moon Lord is known for its challenging combat mechanics, requiring players to defeat its two hands and a head by attacking the eyes that appear on them. Once all three eyes are destroyed, a core opens on its chest that also needs to be defeated. The Moon Lord drops a majority of the endgame items, including the Meowmere, and Luminite, an ore used to craft many endgame armor sets and tools. Therefore, learning how to fight the Moon Lord is crucial for players aiming to reach the endgame content of Terraria.

How can you summon the Moon Lord in Terraria? toggle section
In Terraria, the Moon Lord can be summoned in two ways. The first method is by defeating all four of the Celestial Pillars, which triggers the Moon Lord's arrival after a short delay. The second method is by using a Celestial Sigil, an item that can manually summon the Moon Lord when used. Both methods will lead to an epic showdown with the lord of the moon, so be prepared for a challenging fight!

What happens after the status message 'Impending doom approaches...' appears in Terraria? toggle section
In Terraria, after the status message 'Impending doom approaches...' appears, it signifies that the Moon Lord, the final boss of the game, is about to spawn. This happens one minute after the message appears. The 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. If you're using the Celestial Sigil, the Moon Lord will spawn in just 12 seconds after the message. So, get ready for a thrilling fight!

What is the significance of the Golem in relation to the Moon Lord in Terraria? toggle section
In Terraria, the defeat of the Golem is a significant event that sets the stage for the appearance of the Moon Lord. Once the Golem is defeated, Cultists spawn at the Dungeon's entrance. When these Cultists are killed, it summons the Lunatic Cultist and then the Lunar Events, provided certain other conditions are also met. This chain of events eventually leads to the summoning of the Moon Lord, the final boss of Terraria. Alternatively, the Moon Lord can be summoned directly using the Celestial Sigil.

What is the Celestial Sigil and how is it used in Terraria? toggle section
The Celestial Sigil is a boss-summoning item in Terraria, specifically used to summon the Moon Lord, a post-Hardmode boss. It's crafted from 12 / 20 of each of the Lunar Fragments. Unlike other summoning items, the Moon Lord doesn't appear immediately after the Celestial Sigil is used. Instead, it takes 12 / 60 seconds for the Moon Lord to actually show up. The Celestial Sigil can only be used under certain conditions: the world must be in Hardmode, the Golem must have been defeated, and there should be no ongoing invasions.

Behavior

The Moon Lord has two hands and a head that must be killed before his core becomes available for attack. He positions his two hands on either side of the player some distance away.

Each hand, as well as his head, contain a vulnerable eye-like target that is each periodically closed off and opened via an eyelid. These may only be damaged during their "open" states. The core, which is the only part required to be destroyed in order to defeat the boss, only becomes vulnerable when all eye sockets are destroyed.

Moon Lord can teleport to players if all of them get too far out of range.

Attacks

Template:Item/options

  • The Moon Lord's hands move away from the core and their eyes spawn several Phantasmal SpherePhantasmal Spheres. After a couple seconds, they explode, dealing heavy damage. If the player is far enough away, they simultaneously charge the player before exploding, though they cannot travel at an angle higher than approximately 30 degrees in any direction.
  • The hand eyes also spawn multiple Phantasmal EyePhantasmal Eyes, which move in all directions for a short while before homing in on the player. Like the Phantasmal Spheres, they cannot travel at an upward angle, so they can be evaded by swerving upwards. 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. They explode upon contact with a block or player.
  • The hand eyes also occasionally fire two Phantasmal BoltPhantasmal Bolts in quick succession, which pass through blocks and lead the player, requiring swerves to avoid.
  • When attached to the Moon Lord's head, the head eye periodically opens for a few seconds, and then fires a Phantasmal DeathrayPhantasmal Deathray: a large laser that sweeps upward over the player. This is by far Moon Lord's most damaging attack. Afterward, the head eye blinks a couple times, and fires two Phantasmal BoltPhantasmal Bolts (similarly to those of the hands), and then closes. The deathray cannot pass through solid blocks.
  • The mouth periodically attempts to attach a Tentacle to the player. The Tentacle can reach through solid blocks. Once attached, it spawns multiple Moon Leech ClotMoon Leech Clots, which are enemies that travel from the player to Moon Lord's mouth. Any Moon Leech Clot that reaches the mouth without being killed returns 1000 health to one of Moon Lord's parts (one that has not yet been defeated).
  • The Tentacle also inflicts the Moon Bite debuff, preventing any life-steal effects from weapons/armor like Vampire Knives or Spectre Armor for 14 seconds (16 seconds in Expert mode).
  • When a hand or head target is defeated, it becomes a thorny crevice that deals damage on contact.
  • Additionally, when a head or hand target is defeated, a True Eye of CthulhuTrue Eye of Cthulhu spawns, which cycles through four different attacks:
    • The eye spawns Phantasmal EyePhantasmal Eyes, which behave similarly to when before the eyes were defeated.
    • The eye spawns six Phantasmal SpherePhantasmal Spheres in a hexagonal formation around itself, which after a few seconds will charge directly at the player, dealing a significant amount of damage to the player. This is by far the dominant source of damage in the second phase and should be avoided by swerving/dashing.
    • The eye fires two Phantasmal BoltPhantasmal Bolts at the player, similar to those from the hand eyes
    • Finally, the eye charges and fires a lesser Phantasmal Deathray, smaller and dealing significantly less damage. This cannot pass through solid blocks.
    • The eye dances outward in a spiral, dealing a small amount of damage upon impact.
    • The True Eye of Cthulhu is invincible and will only despawn if either all players or Moon Lord is defeated. Also, the eye tends to remain stationary for most of its attacks.
    • He can teleport and attack players with all his attacks when another player dies in a group of two or attack the last player in a group of three.Template:Item/options

Notes

  • Moon Lord can be summoned with a Celestial Sigil before defeating the Lunatic Cultist in any world where Golem has been defeated.
  • Some of Moon Lord's attacks can be avoided using the 200 NPC limit, e.g. the True Eyes of Cthulhu will not spawn when there are 200 other NPCs present in the world.
  • If the player leaves the world after the message "Impending doom approaches...", the Moon Lord will not spawn.
    • This could be useful for players who aren't ready to fight the Moon Lord yet and/or if they don't have enough Lunar Fragments to use.
  • If the player escapes from the Moon Lord, he will teleport to the player. Teleporting home to get healing from the Nurse might result in her death.
  • Every NPC takes reduced damage from The Moon Lord, especially the Nurse. They only take 20-35/40-60 damage for other NPCs and 10-30/25-45 for the Nurse, and for all of them 100-130/125-180 for the Phantasmal Deathray attack. However, this changes in Moon Lord's second form, as the True Eyes of Cthulhu deal around 45-85/60-105.
    • In Multiplayer, Moon Lord will attack the nearest player. Players can take turns teleporting home to get healing from the Nurse.
  • While the Moon Lord is on screen, the sky will turn dark and the world will appear hazy and shadowy with blur effects. In Multiplayer, this only happens if the player is within 130 blocks of the Moon Lord.
  • In Expert mode, the Treasure Bag will not drop a Portal Gun if the player opening it already has a Portal Gun in their inventory. However, he will always drop it in normal mode.
  • If Moon Lord uses Phantasmal Deathray, it will still be used if his head is defeated until finished.
  • If all players die during the Moon Lord's death animation, he will despawn and drop nothing.
    • His eye sockets still deal contact damage during that period. It is wise to move away from the boss once he is defeated.

Tips

For more elaborate strategies on defeating Moon Lord, including weapon and arena recommendations, see Guide:Moon Lord strategies.
  • With the Gravitation Potion, you will be moving vertically fast enough to avoid most of his attacks, but it might be difficult to hit his vital parts, unless you use homing capable attacks.
    • You can also use it to dodge the Phantasmal Deathray.
  • Using a weapon that can attack through blocks, such as the Solar Eruption, can mitigate incoming damage while making evasion less complicated. Two rows of blocks (one to run along and one above to protect from lasers) can be quite effective. Make sure the rows of blocks are separated widely apart so that you can avoid the Phantasmal Spheres that could come horizontally from the True Eyes Of Cthulhu.
  • The Moon Lord is not immune to Ichor nor Betsy's Curse, which can drastically speed up the fight. Do note however, that every time an Eye closes all debuffs will be removed from it.
  • A large portion of the Moon Lord's attacks, including the Phantasmal Deathray he emits from his head, are incapable of passing through blocks. Consider seeking cover to avoid these attacks during the fight.
  • The Moon Bite debuff, which prevents life-steal abilities, is reliant on a tentacle making contact with the player. It is possible to move outside of its maximum range, avoiding the debuff and allowing effects to once again heal the player. However, hitting him becomes harder this way.
  • Avoid killing the head last. This eye remains closed for significantly longer than those in the hands, so you will have to endure the relentless attacks of two Eyes of Cthulhu while waiting for it to open again.
  • Since the hands will start dealing melee damage after they are defeated, running away on an asphalt sky bridge will become an issue if not properly prepared to dodge the hands. Most other strategies are unaffected.
  • It is unwise to use Vampire Knives or the Spectre Hood as the Moon Bite debuff occurs very often, which disables life steal from these items.
    • However, it does not stop health regeneration boosts, so the effects of Nebula armor and the Life Drain are not affected.
  • The Moon Lord teleports to the player closest to him if all players go out of range.
  • You can use Minecart Tracks or platforms going across your world to help avoiding the attacks. Moon Lord will still try teleporting to you, but his attacks cannot catch up. The Mechanical Cart is the best way to move fast along the tracks.
  • Owning a Rod of Discord can provide a great deal of assistance, as it can be used to easily evade Moon Lord's Phantasmal Death Ray. Use it sparingly though, as Chaos State can kill or greatly damage an unaware player.
  • The Cosmic Car Key can provide a huge advantage, as it makes avoiding his attacks easier than on the ground, and also goes slightly faster than the Moon Lord.
  • It is a good idea to use the Chlorophyte Bullets or some homing weapons, because you can focus on dodging and you don’t need to aim as much since the projectiles will chase an undefeated part.
  • Simply having more players on the world will make things significantly easier, because although Moon Lord will have more health and heal more due to his leeches, making the fight much longer than normal, it will also lengthen how long the players can last.
  • The Cute Fishron is capable of mildly outrunning the Moon Lord with its speed bonus (the player must be under half health or have recently touched a liquid). However, care must be taken to stay just far enough away, but not so far as to trigger him to teleport to the player.
    • This can be consistently used as a strategy if the player makes an arena water-filled or populated with water Bubbles.
  • The Phantasmal Deathray can be dodged more easily with the use of a set of wings with high ascent speed such as Fishron Wings, as well as an item that enables dashing such as the Tabi.
  • The Unicorn Mount is also a great way to avoid attacks as it is vastly faster than the Moon Lord. This in conjunction with a one way teleporter and Chlorophyte Bullets makes for an easy Moon Lord fight.

Trivia

  • Despite a mid-development comment by Cenx that this would not be the case, Moon Lord resembles common depictions of Cthulhu, a creature first imagined by H. P. Lovecraft in his story, The Call of Cthulhu. Fans commonly speculated prior to the release of 1.3 that Cthulhu would be the final Terraria boss (which in turn arose partly due to an early concept design floated by the development team).
  • Terraria's final boss was originally going to be the Moon itself descending on the world, but Cenx later stated that this idea had been scrapped.[1][2]
  • Despite being the final boss of the game, Moon Lord drops less money than even pre-Hardmode bosses. He does not drop money on Expert.
  • The Wall of Flesh and The Destroyer are the only other two bosses that do not despawn when the player gets too far away.
  • Due to the colors of the boss and the names of a few of his projectiles, this boss may have been designed from the Vortex Pillar.
  • Despite being the final boss, Moon Lord has the lowest amount of debuff immunities, being immune only to Confusion (which is also the case for about 70% of Terraria's enemies).
  • Moon Lord's resemblance and relation to Cthulhu have a basis within Lovecraft's "Cthulhu Mythos" as Cthulhu has two brothers, an identical twin named Kthanid and a half brother named Hastur, both taking a form similar to Cthulhu's, though Moon Lord is more than likely in reference to Hastur as both have a trademark sign that signals his arrival (see the Celestial Sigil and the Mysterious Tablet) as well as the fact that Kthanid is "as good as his brother is evil" and therefore making it unlikely that he would attack the player.
  • NPCs cannot attack the Moon Lord.
  • According to Cenx, spriting the Moon Lord took over a month.[3]
  • Red has stated that, if 10,000 signatures and 15 dollars are gathered, he would make the lower half of the Moon Lord a boss. However, the validity of this statement is questionable.
    • Both criteria have since been met, however.
  • The Moon Lords design looks like it consists of three of the main bosses in pre-hardmode including, Skeletron, Eye of Cthulhu, and Brain of Cthulhu.
  • Upon defeating one of the 3 "eyes" of the Moon Lord, when the cursor is located on the eye, a name displays directly above it which reads "True Eye of Cthulhu" which lead many to theorize that the pre-hardmode boss Eye of Cthulhu is a fake or a replica and that the Moon Lord is indeed the Cthulhu itself.
