"...an aberrant behemoth from beyond the stars."

The Moon Lord is a Hardmode boss. Defeating the Moon Lord is required to unlock the final broad group of bosses and content in the Calamity mod.

While in Revengeance Mode and Death Mode, the Moon Lord gains several changes to his AI and stats, making him substantially more difficult to fight.

Spawn

The Moon Lord can be spawned by fulfilling either of these conditions:

• Destroying all four Celestial Pillars;
• Using a Celestial Sigil.

Behavior

In all modes, True Eyes of Cthulhu no longer deal contact damage.

In Revengeance Mode

Phase 1

The Moon Lord spawns a minute after being summoned and immediately begins attacking, cycling through his roster of attacks. He teleports more frequently based on his distance from the player, attempting to stay close at all times.

The Phantasmal Deathray attack sweeps noticeably faster, making it more difficult to avoid. Following the Deathray, the Moon Leech Clots spawned by the Tentacle heal the Moon Lord for 1,250 health each instead of 1,000. Phantasmal Sphere attacks are more spread out and move slowly initially, accelerating over time. Phantasmal Eyes home in for a while longer than normal.

Defeating each of the Moon Lord's eyes does not disable them, and will instead spawn several True Eyes of Cthulhu. The Moon Lord's eyes continue attacking afterward, but at a reduced frequency and with lower velocity projectiles. True Eyes of Cthulhu do not use their deathray attack in Revengeance Mode, and will instead stick together and attack in sync.

Phase 2

After defeating all three of Moon Lord's eyes, his core becomes exposed. Following this, players will take 10% more damage from all sources until the Moon Lord is defeated or leaves.

In the second phase, the Phantasmal Deathray will now penetrate blocks, forcing the player to dodge the attack in order to avoid it.

In Death Mode

• Clots heal for 1,500 instead of 1,250.
• All projectiles have their velocity increased.
• The Moon Lord and True Eyes of Cthulhu are more aggressive.

On the For the worthy seed

• Moon Lord's Phantasmal Bolts are predictive.
• Moon Lord's Phantasmal Deathray sweeps around even faster.
• Moon Lord and True Eyes of Cthulhu are more aggressive.
• Moon Lord retains maximum aggression regardless if the True Eyes of Cthulhu are out or not (Rev+).

During the Boss Rush

• Moon Lord is the first of the Tier 4 bosses to appear, and the final vanilla boss in the Boss Rush.
• Moon Lord's total health is set to 3,100,000 / 4,650,000 / 7,980,000 .
  • The Moon Lord's head is set to 600,000 / 900,000 / 1,080,000 health.
  • The Moon Lord's hands are each set to 450,000 / 675,000 / 810,000 health.
  • The Moon Lord's core is set to 1,600,000 / 2,400,000 / 5,280,000 health.
• Gains the predictive Phantasmal Bolts from the For the worthy seed.

Resistances

• The Moon Lord's Core takes:
  • 10% damage from the True Biome Blade's Mercurial Tides attunement.
  • 85% damage from the Pestilent Defiler.

Aftermath

• New enemies begin spawning in the Hallow and the Underworld.
• Luminite and Exodium Clusters are generated as Planetoids.
• Enemies in the Dungeon are buffed and begin spawning Phantom Spirits.
• The Bandit begins selling the Celestial Reaper.
• Shockstorm Shuttles can now drop Exodium Clusters.
• Sky or Azure Crates will contain Exodium Clusters.

Gearing Up

For a Normal and Expert mode guide to Moon Lord, see Moon Lord strategies on the vanilla wiki.

Armor

• The Hydrothermic armor and Astral armor sets are the preferred types for all classes.
• Beetle armor is a viable alternative for Melee users wishing to absorb damage. The Beetle Shell is preferable to the Beetle Scale Mail, as it features the highest total defense of any armor at this stage as well as the Beetle Endurance buff.
• The Plague Reaper armor's armor set bonus, paired with the Plague Hive, can be devastatingly effective for Rangers - however, the negative effects of the set bonus debuff make it a risky strategy.
• Summoners can use Spooky armor, Plaguebringer armor, or Valhalla Knight armor. Valhalla Knight armor provides an exceptionally high defense for the Summoner class, and its damage boost synergizes well with playstyles that use fewer minions.

Accessories

• At this point of the game, Angel Treads are a must.
• The Asgard's Valor can be used to provide a dash.
• The Blood Pact is an accessory that doubles max health, but causes the player to get critically hit 25% of the time.
• The Community's decent buffs to all stats are useful here.
• The Fishron Wings are almost the highest-tier wings available at this point.
  • Despite that, the Hadal Mantle can be used because of its vertical mobility.
• The Celestial Shell and Fire Gauntlet should be used by melee players.
• The Recon Scope or Deadshot Brooch should be used by rangers to boost damage.
• The Sigil of Calamitas or Celestial Emblem should be used by mages to increase damage output.
• The Star-Tainted Generator or Statis' Curse are useful for summoners.
• The Vampiric Talisman is almost essential for rogues, and the Dark Matter Sheath is useful if prioritizing stealth strikes.
• The player should also use their respective class emblems to maximize the damage output.

Weapons

Melee

• The Briny Baron has a powerful but situational left-click attack that can be supplemented by its safer right-click function, giving the player the versatility of multiple weapons in one.
• The Solar Eruption and Daybreak are cost-efficient options. The Solar Eruption has a high DPS and moderate range but suffers from its unpredictable swing pattern. Daybreak is less powerful but can be used from a safer distance with more accuracy.
• The Astral Blade's unique damage mechanic and Astral Infection debuff make it an excellent choice for the first portion of the fight.
• The Grand Guardian is a riskier option as it lacks a ranged projectile, but deals very high true melee damage and can lower Moon Lord's defense.
• The Fault Line is the best yoyo at this stage.

Ranger

• The Phantasm is an excellent option with a high DPS, especially when paired with Terra Arrows.
• The Astral Bow is another powerful bow that is crafted with different resources, if the player is conserving lunar fragments.
• The Conference Call is a heavy-hitting gun, best used with Chlorophyte Bullets.
• Both of the Scorpio's fire modes deal high damage, though the secondary fire generally lacks the radius to damage multiple Moon Lord body parts at once.
  • The Spectralstorm Cannon's circling projectiles can be used to hit different parts of Moon Lord's body if used properly.
• The Vortexpopper, when combined with Chlorophyte Bullets, should make the fight fairly straightforward.
• The Hive's rockets, bees, and Plague debuff do very high damage to the boss.

Mage

• The Swarmer can do good homing damage in this fight when paired with the Plague Hive.
• Nebula Blaze has homing projectiles and decent damage, but has a high mana cost.
• The Lazhar has precise targeting and relatively good damage.
• The Nano Purge deals high damage once it has reached its full rate of fire.
• The Vesuvius, especially with its right-click attack, can do extraordinary damage to the boss.

Summoner

• The Starspawn Helix Staff and Stardust Cell Staff have similar damage outputs, differing primarily in their movement mechanics (the Starspawn Helix Staff spawns a probe that orbits the player in proximity, while the Stardust Cell Staff spawns cells that teleport after the player's target.)
  • Though heavily neutered from its vanilla incarnation, the Stardust Dragon Staff is still effective with maximized minion count and damage accessories, as it has a range that far exceeds either aforementioned staff's minions.
• The Spikecrag Staff is the best sentry available.

Rogue

• The Radiant Star is an excellent choice for this boss due to its large area of effect and ability to hit multiple eyes.
• The Regulus Riot's homing capability and high damage are useful if keeping some distance from the Moon Lord.
• The Shard of Antumbra has a stealth strike with homing stars, while its main attack is very effective at close distances.

Classless

• The Golden Gun is a weapon that deals classless damage.
• The Lunic Eye can lower damage reduction.
• Yanmei's Knife is a close range option that deals classless damage.

Tips

• Though the Moon Lord can be fought at any point in Hardmode (through the use of an Eidolon Tablet and defeating the Lunatic Cultist and proceeding Lunar Events), fighting him before the player has defeated most other Hardmode bosses and acquired proper gear is generally ill-advised.
• As in vanilla, the Moon Lord takes one minute to spawn after he is summoned regardless of the method. This period is invaluable for reaching the player's arena and making other last-minute preparations.
