Alatreon is a Large Monster in Monster Hunter World (MHW). アルバトリオン (Arubatorion) in Japanese.


Known as a symbol of destruction, people fear even uttering it’s name. It’s rumoured to control all of the elements, but most, if not all, records of its existence have been burned.

Alatreon Details & Locations


Alatreon Combat Info

  • There are two events that allow you to fight Alatreon (Evening Star and Death Star). They rotate on a daily basis and differ from player to player.

  • The Evening Star is the quest where Alatreon will always start in Fire Active.

  • Dawn of the Death Star is the quest where Alatreon will always start in Ice Active.

  • Alatreon can use attack from any element in any form, though he tends to prioritize the ones that corresponds to his active state.

  • Elemental damage is primordial against Alatreon, considering doing enough elemental damage will weaken its supernova, and it will cart the hunter in almost every case if not weakened.

  • Alatreon's elemental weakness changes depending on its active element.

  • Alatreon is extremely resistant to all ailments and it will take a lot of time for you to inflict it just once.

  • Kinsect Extracts:

    • Red: Head

    • Orange: Legs

    • White: Wings

  • You can obtain Shiny Drops by breaking his horns, performing a successful wall-slam and everytime you weaken his nova.

  • It is possible to survive the unweakened supernova by putting down a Health Booster and eating a well timed Astera Jerky but it is pretty difficult, and the intended way is to deal enough elemental damage to weaken the supernova.

  • Although Water and Thunder are marked as 2 stars weaknesses for Fire and Ice Actives respectively, Fire and Ice are a lot more effective against their counterpart, even though they are only marked 1 star higher.

  • Dragon damage is always effective against Alatreon no matter his active element, but it is significantly less potent than any other element.

  • A popular strategy is to wait until Alatreon goes into Dragon Active before wall-slamming him, since this makes breaking his horns extremely easy.

  • Alatreon can be very tricky to wall-slam, as it only works if he hits one of the three big rock formations on the edge of the arena. Alternatively, Alatreon can be slammed down to the ground when he's flying.

  • Alatreon can be stunned with Flash Pods (even out of the air), but only when he's not enraged.

  • Getting up immediately after getting hit by Alatreon is not always a good idea considering it tends to combo a lot of its move, waiting on the floor longer while invincible could save a faint.

  • Give your Palico the Plunderblade. You might not complete the quest, but you can still farm Alatreon materials until you eventually do succeed.

 Alatreon's Elemental Rotatation and how to take advantage of it

Alatreon has three "Elemental States": Fire, Dragon and Ice, through which he will circle during the hunt. Alatreon switches elements every 3 minutes. Depending on the quest you fight Alatreon in, the rotation will be different.

  • In the Special Assignment and the Event Quest "The Evening Star", Alatreon will start in Fire Active and switch as follows:

    • Fire to Dragon to Ice to Dragon to Fire

  • In the Event Quest "Dawn of the Death Star", Alatreon will start in Ice Active and switch as follows:

    • Ice to Dragon to Fire to Dragon to Ice

Every time Alatreon Switches from Dragon to the next element he will perform the Escaton Judgement attack. Hopefully, Alatreon's power has been contained enough at this point to make the attack survivable.

By breaking Alatreon's horns after he shifts to Dragon, the next Elemental State can be avoided, and Alatreon will be forced to switch to the other element next. The rotation of the elements resets back to the start.

  • Example: If Alatreon switched from Fire to Dragon and you break his horns, he will be forced to switch to Fire again, after he performs the Escaton Judgement. Afterwards, he switches to Dragon, and after that to Ice, if you don't break his horns a second time.

  • Unless the group uses mostly Dragon, Thunder or Water weapons, eliminating either Fire Active or Ice Active from the rotation is critical to success.

  • If Alatreon starts in Fire Active, he has a 3 star weakness to Ice and is immune to Fire. Bring Ice weapons and eliminate Ice Active from the rotation.

  • If Alatreon starts in Ice Active, he has a 3 star weakness to Fire and is immune to Ice. Bring Fire weapons and eliminate Fire Active from the rotation.

Going blindly for the horns can be detrimental to the hunt! If you fail to break Alatreon's horns and are stuck with the wrong Elemental state DO NOT break the horns once Alatreon switches back to Dragon!

  • Example: Your team is running 3 Ice weapons, one Light Bowgun. If Alatreon switches to Ice, you can't effectively contain his power in this stage. Once it switches to Dragon again, you may contain Alatreon's power once to survive the Escaton Judgement. But, if you break the horns, Alatreon will SWITCH BACK TO ICE NEXT! The horns should NOT be broken in this case!

Surviving the Supernova (Escaton Judgement)

  • Alatreon's Ultimate Attack. It is indicated by the entire Arena filling with Frost of Fire and the Sound getting notably muffled. After roughly five seconds, Alatreon releases a massive, arena-wide elemental blast, that deals a set amount of damage in 5 seconds.

  • The Supernova functions identically to Lunastras Supernova. Only this time, there is no running from it.

    • Dodging, including the Superman-Dive, and most mantles are useless. The Vitality Mantle will give you 100 additional health, reducing the effects of the Supernova somewhat.

    • The damage is dealt in form of red health without stagger or knockback. It is not possible to i-frame it, and it will not trigger Vigorwasp Revival.

  • Dealing enough elemental damage to Alatreon will cause him to do a special topple animation (similar to Velkhana when you break her ice armor). Once this happens, the next Escaton Judgment will be severely weakened.
  • The damage dealt by the nova is dependant on how many times Alatreon has been toppled through elemental damage before Escaton Judgment. This counter resets after every EJ.

    • 0 Times: The supernova deals over 400 damage in 5 seconds. It is only possible to survive this nova through extreme coordination and perfect timing, but you shouldn't count on that.

    • 1 Time: Deals around 280 damage. Easily survivable with two Astera jerkies / Sushifish scales without Health Boost or Health Booster. 

    • 2 Times: The supernova now only deals 140 damage in 5 Seconds, making it completely survivable without healing if you start at full 150 health.

    • 3 Times: Alatreons Power is fully contained and the Supernova deals a miniscule amount of damage.

  • Players can survive Escaton Judgment more easily by getting together and placing down their Health Boosters at the same spot, since they stack. Lifepowder and Dust of Life can be also be beneficial.


Recommended Skills

  • Health Boost: Extremely useful considering Alatreon's high damage output.

  • Blight Resistance: All Alatreon attacks are elemental, and can inflict blights, this skill eliminates a huge part of the hassle of this fight.

  • Dragon Resistance: Since Dragonblight shuts down your elemental damage (required to weaken Escaton Judgment), it is very important to make sure you aren't hit by this blight. Having a dragon resistance of 20 or more will prevent him from inflicting Dragonblight, but you still will be hit by other blights, which in turn will proc Coalescence.

  • Coalescence: This is almost a free damage boost considering how many blights Alatreon inflicts to the hunters. Note that Blight Resistance lv3 will nullify Coalescence (use lv2 instead).

  • Agitator: Alatreon stays in enraged state for a very long time, making this skill very good.

  • Fortify: Mainly useful if you intend to bruteforce Alatreon by ignoring his elemental damage mechanics.


Weapon Match-Ups

Dual Blades

Champion of elemental damage, it can benefit from Alatreon's high sever hitzones as well. Keep in mind some of his attacks might be hard to see if you're focusing the backlegs.

Insect Glaive

The kinsect alone has higher elemental output than most weapons in the game, making it possible to hit the elemental topple even without any element on the weapon. Alatreon also has plenty of openings to use Descending Thrust on him. 

Sword and Shield

The weapon could have some issues hitting Alatreon's head sometimes, but overall its high raw damage output allows it to clear the hunt easily.


Bow suffers a little against Alatreon due to the awkward shot hitzones (see Bowguns below for more details). It can still hit elemental topples easily thanks to the high elemental damage output.

Hunting Horn

Alatreon might not get stunned easily but it is possible. The best part about the Hunting Horn are the songs though. Especially Elemental Resist Up and Remove Blights will be very helpful. Ultimately more of a support weapon against Alatreon.


Overall pretty moderate elemental damage, but a relatively safe weapon overall.

Charge Blade

Can score topples very easily thanks to the high elemental damage output of phials and Savage Axe ticks. The weapon has also a relatively high modifier when it comes to the elemental topple buildup.

Switch Axe

In sword mode, the weapon has pretty high elemental output, especially when using power element phials. In axe mode, the increased part break values of Power Axe will contribute towards tripping Alatreon.


Greatsword is surprisingly good against Alatreon because of its high innate part break values, which count towards the elemental topple. However, unexperienced players might struggle because of the low elemental output of the weapon.


Like Greatsword, it has comparatively poor elemental damage. It is recommended to abuse spinning bludgeons on the head or the forelegs to rack up as much elemental damage as possible.


It can apply elemental damage decently, but it might have issues catching up with Alatreon while he jumps around the arena.


It is recommended to use melee attacks rather than shelling on Gunlance until Alatreon topples.


While Elemental Ammo can score the elemental topple pretty easily, the awkward shot hitzones (which are very low on parts that have high elemental hitzones) and the inability to use Farcaster to restock makes it one of the worst match-ups against Alatreon. For this reason, it is recommended to use Pierce Ammo instead and focus Alatreon's chest. Note that this will likely require you to cart during the nova.

Best Armor Sets


Best elemental set for Kjarr weapons and bowguns. Increases the elemental damage significantly but at the cost of health. If you are confident in your abilities to avoid damage, go ahead. Keep in mind however that Alatreon can quickly cut your health bar in half with most attacks.

Raging Brachy

Two pieces for Agitator Secret is a pretty good deal, especially since Alatreon stays enraged for long periods of time.

Silver Sol

True Critical Element will amp up your Elemental Damage. However it requires 4 equipment slots and is vastly inferior to Kjarr weapon + Safi set bonus.

      O dragon of the elements
      See the Hunters pitch their tents
      A battle had begun
      A time of forever done
      If this fight is lost
      Hunters blow your horns
      Hone your blades and release your arrows!

        The run should be perfect. Kill him before the third eschaton breaking both horns and get it over with in sub 20 min... or be a scrub and use dragon element and fight him for 30 minutes without breaking a single horn, while loudly proclaiming how ‘easy’ he is on forums.

              Now after 6 solo tries I still fail this quest but I broke its first horn within 4 minutes! I am using longsword so my strategy is primarily perfect iai spirit slash timing. My goal is not to play safe, rather I need to counter all his attacks and maximize elemental/ raw dps. The only way to kill this solo is by speedrunning it.

                I told myself I'll solo him , since I have a sort of rivalry with him from 3U.
                The first few times I tried, I failed utterly, mostly because it took me a while to realise my safi-resentment set didn't work, because of my health regen augment.
                Switched my armour to an agitator build, had 560 Element with IG.
                Killed him first try with that set, 23minutes, was far from a perfect run, could definetly shave the time down by 2-3 minutes.
                I really like what they did with the fight, I'm one of the few people who has nothing against the Escaton Judgement, and even though you can argue it's "fake" difficulty, I still enjoy more of a challenge. With my set, I toppled him in 2 minutes, and then proceeded to bully him to the ground. I really think they did him well, the weapons could've been more diverse though.

                  Made it (the short one, but still). Switched to support for this fight (lancer primary, to fast for me yet). Kulve Taroth + Frostfanng Barioth SnS.
                  But to be honest - Raging Brachy was way more harder, maybe because he is the first of an end game challenge.
                  Good luck to everyone!

                        Feel kinda bad for the guy. first got beaten up by Fatalis and retreated with only 30% of his health left, and in "Dawn Triumphs" we just come in and finish him off. btw can anybody confirm this is true? I heard that Alatreon was weak because Fatalis beat him up badly but can anyone clarify?

                            I’ve tested this btw, you can wear a vitality mantle and survive his supernova while he is NOT weakened as long as you drink a mega potion and have close to max health
