Moon Lord is the final boss in Terraria. Because of its high health and its numerous, highly damaging attacks, it is generally considered the hardest boss in the game.

The Fight[edit | edit source]

The Moon Lord's main attacks come from the Eyes on its hands and forehead, which are also its weak points where it can be damaged.

When the eyes on the hands are exposed, they will alternate between spawning Phantasmal Eyes and shooting Phantasmal Spheres. The eye on its forehead will instead charge up the Phantasmal Deathray, and then fire it based on the player's position.

The eyes can only be damaged on their "active" state and they will always shoot 2 Phantasmal Bolts before closing.

When an eye is defeated, it will detach from the main body and spawn a True Eye of Cthulhu, an unkillable enemy that uses weaker versions of the Moon Lord's attacks. The empty eye sockets will also reveal fangs which do contact damage if touched, but the Moon Lord won't directly attack with them.

Occasionally, a tongue will spawn from its mouth and chase the player. If it connects, it will inflict the Moon Bite debuff, which prevents healing from the Vampire Knives and the Spectre Hood. The Moon Leech Clots spawned from the tongue will heal one of the Moon Lord's parts for 1000 HP if they reach its mouth.

The Phantasmal Sphere is the boss’s second strongest attack. It is difficult to escape its range, so the directional dodge provided by the Master Ninja Gear is very important.

The Phantasmal Deathray is one of the strongest attacks in the game, and the player must always watch out for it, especially on Expert mode. It can very easily finish off a player at medium health, so it must be dodged at all costs. It is only fired by the eye on its forehead, so you must be prepared for it when it opens. The safest way to dodge it is by flying over him with Wings, preferably Fishron's. It can also be dodged with a Rod of Discord by teleporting out of its path. Because of this attack it is a bad idea to keep the Moon Lord offscreen, as the player won't be able to see it coming.

The Phantasmal Bolts don't do a lot of damage, but they are hard to dodge as the Moon Lord doesn't shoot directly at the player; it instead tries to predict their position, and does so very accurately. The eyes will look at the player when preparing the attack, so you can predict it as well.

After all 3 eyes are defeated, the Moon Lord's core will be revealed, and what is arguably the hardest part of the fight will begin. The True Eyes of Cthulhu attack very frequently, quickly overwhelming even skilled players. Running away in this case is better, as the True Eyes' Deathrays have much shorter reach compared to the Moon Lord's.

General tips[edit | edit source]

This content is transcluded from Guide:Practical Tips#Combat.

  • It is suggested to build houses for the DryadDryad and the NurseNurse NPCs in your arena. The former casts the Dryad's BlessingDryad's BlessingDesktop VersionConsole Version buff, which increases your defense and provides you with a thorns-like effect, while the latter can heal and remove debuffs instantly, at the cost of some coinscoins.
  • Bosses are displayed on the Minimap: Follow the boss's icon to track it when you're struggling to find it. You can identify the boss icons by checking their respective wiki pages.
  • Once you have freed the MechanicMechanic in the Dungeon, you can use WireWire to enhance your arena with TrapsTraps and helpful HeartHeart and Star StatuesStar Statues. The former help to damage the enemies, though be careful to set them up correctly in order not to hurt yourself during the battle. The latter will spawn heart and star pickups, respectively. Connect these devices to timerstimers.
  • It may be useful to summon and kill the Eye of Cthulhu before summoning any harder boss in order to spawn an extra one-use pool of hearts.

Terrain preparation[edit | edit source]

If one is having problems fighting the Moon Lord, a skybridge can be built to make the fight significantly easier. Ideally, it should extend quite far from either side of your spawn point (700-1000 platform blocks should suffice). The Moon Lord will not despawn unless all players are dead, meaning you can outrun him and heal for a while if need be. However, straying too far will cause the Moon Lord to teleport on top of you, so careful spacing is required. This is of less concern in multiplayer, as the Moon Lord will only chase one player at a time, giving the others time to retreat and heal up if necessary. A long straight Minecart Track paired with the Mechanical Minecart will help you avoid most of his attacks. Make sure to hammer the ends for bumpers or make a loop to return to the straight track.

A simple roof made of solid blocks is useful for blocking the Phantasmal Deathray. Thickening the roof will also mitigate the explosions of the Phantasmal Eyes. You can open up holes in the roof to shoot through when the Deathray isn't active, or you can leave the roof without any holes and damage the Moon Lord exclusively with weapons that can phase through walls.

Asphalt can still be used to dodge the tongue if you value the ability to use Vampire Knives. When the Moon Lord teleports with his tongue already chasing you, the tip of the tongue will not teleport with him. This allows you to completely outrun the tongue, avoiding Moon Bite and allowing Vampire Knives/Spectre armor to work normally.

Gearing up[edit | edit source]

Armor[edit | edit source]

  • For melee characters, the Beetle armorBeetle armor is the best available. The Beetle Scale MailBeetle Scale Mail provides better offensive bonuses, while the Beetle ShellBeetle Shell is much tankier, especially if you can avoid taking hits frequently. The latter is a viable option even for those who don't wish to use melee weapons.
  • For ranged characters, the Shroomite armorShroomite armorShroomite armorShroomite armor is the strongest available.
    • The set bonus will be mostly useless due to the importance of dodging the Moon Lord's attacks, so the chest piece can be swapped with the Valhalla Knight's BreastplateValhalla Knight's Breastplate if more survivability is needed.
  • For a magic user, the strongest armor is a hybrid set consisting of Hallowed HeadgearHallowed Headgear, Valhalla Knight's BreastplateValhalla Knight's Breastplate, and Dark Artist's LeggingsDark Artist's Leggings.
    • Dark Artist's RobesDark Artist's Robes can be substituted into the above setup for even more damage, though it gives up a significant amount of survivability.
    • Spectre armorSpectre armor is another viable option. The Spectre HoodSpectre Hood is not very useful due to the Moon Bite debuff.
  • A summoner should summon their minions while wearing Spooky armorSpooky armor and then equip Tiki armorTiki armor for an extra, weaker minion and slightly higher defense.

Weapons[edit | edit source]

Every class will benefit the most from the weapons made with Celestial fragments, with some exceptions.

For Melee users:

For Ranged users:

For Magic users:

  • Nebula BlazeNebula Blaze deals decent DPS and is accurate, but its mana cost is difficult to sustain.
  • The RazorpineRazorpine and Blizzard StaffBlizzard Staff have higher DPS than the Nebula Blaze and lower mana cost, but lack the homing effect.
  • Nebula ArcanumNebula Arcanum deals extremely high DPS if you can manipulate the Moon Lord into staying in roughly the same position.
  • Razorblade TyphoonRazorblade Typhoon may be weaker than all the others, but it has a fast, mana efficient projectile which can hit all 3 parts with the same shot.
  • Betsy's WrathBetsy's Wrath inflicts a potent defense-lowering debuff that the Moon Lord is not immune to.

For Summoners:

Accessories[edit | edit source]

Due to the amount of high damaging attacks during the fight, it is better to focus on mobility and damage rather than defense.

  • The Master Ninja GearMaster Ninja Gear and Fishron WingsFishron Wings are essential for mobility. A Frog LegFrog Leg makes wings ascend significantly faster, which helps a lot when dodging.
    • The Cosmic Car KeyCosmic Car Key can be used as a replacement for the above, trading mobility for an extra accessory slot.
  • Damage increasing accessories are very important, such as any Emblem, Celestial ShellCelestial Shell or Celestial StoneCelestial Stone.
  • The knockback from the Phantasmal eyes could hinder mobility at a bad time. A Cobalt ShieldCobalt Shield or better will prevent this.
  • The effects of the Philosopher's StonePhilosopher's Stone are only applied the second a Healing Potion is drunk, so it can be kept in a vanity slot until the player needs to heal.

Every accessory should have the Lucky or Menacing Modifier.

Potions[edit | edit source]


  • As mentioned above, the Rod of DiscordRod of Discord is another way to avoid the Phantasmal Deathray. There is no need to worry about Chaos State, as the Moon Lord uses the attack on a timed interval, allowing for the teleport debuff to wear off.

Specific Strategies[edit | edit source]

Synchronized release[edit | edit source]

For those who want to fight the Moon Lord conventionally, it is highly recommended to synchronize the release of the True Eyes of Cthulhu. To do this, the health of the Moon Lord's head and hands must be brought to zero at a very precise moment in the True Eye of Cthulhu's attack pattern. Prepare by bringing all three of the Moon Lord's eyes to a very low amount of health, and release one. After the True Eye of Cthulhu fires a Phantasmal Deathray, another True Eye of Cthulhu must be released during the Phantasmal Sphere attack that immediately follows the Deathray. The timing is indicated by a unique noise. If done correctly, the newly released True Eyes of Cthulhu will attack in the same pattern, making them far simpler to dodge.

Minecart and Teleporters[edit | edit source]

For this strategy, a very long railway with bumper ends should be made in a straight line. Make sure to build a ceiling above to block Moon Lord's Deathray.

A Minecart's speed makes it very easy to avoid the Phantasmal Spheres and Bolts, and as mentioned previously, the Deathray will be blocked by the Ceiling. When you reach the end of the track, the Bumper end will quickly change your direction while also keeping your momentum. A Teleporter wired from the beginning to end can also serve the same purpose if triggered with a Pressure Plate Track.

Shelter strategy[edit | edit source]

This strategy is based on exploiting the fact that a lot of Moon Lord's attacks can't go through walls.

A half screen-width wide, 6-12 tiles high shelter must be built. Make sure to add Heart Statues, Heart Lanterns and Honey for better regeneration. A weapon with the ability to attack through blocks such as the Solar Eruption must be used to attack him.

While inside the Shelter, only the Phantasmal Spheres will be able to hit the player, making for a very easy fight.

  • A smaller shelter is acceptable. Simply build a small 2-story house mid-air with honey on the top floor (and other items mentioned above except for heart statues), and move the nurse downstairs. When you are damaged below 200 health, simply pay the nurse for more health.

Cute Fishron[edit | edit source]

The Shrimpy Truffle mount from Expert Duke Fishron is mandatory. A large water arena (at least 100x20) large enough when riding Cute Fishron will greatly increase mobility, as well as saving accessory slots that would have been used for mobility. Pumps can be used to speed up the construction of the arena.

With Cute Fishron's speed, you can outrun the Leech, circle around the Deathray and dodge the Phantasmal Spheres quite easily, while also getting a small damage increase.

The Hoik Method[edit | edit source]

This the easiest, but longest way of fighting/farming the Moon Lord. It doesn't require much in the means of equipment, other than what you would probably have already at this point in the game. It will require patience as the battle will be lengthy, but this is a sure-fire way of winning that only requires clicking the mouse to use.

Best example of this method is shown here:
