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 it tends to prioritise the ones that corresponds to it's active state

  • Elemental damage is primordial against Alatreon, considering doing enough elemental damage will weaken its supernova, and it will oneshot any hunter 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 a Shiny Drops by breaking its horns, performing a succesful Wall-Slam and everytime you weaken its nova.

  • Elemental Defense (L) can be an asset considering most of Alatreon's attacks deal elemental damage.

  • Eating for Felyne Insurance can be extremely useful if you're having trouble hitting Alatreon's elemental DPS check.

  • Blight Resistance can be extremely useful if you find blights too annoying, Alternatively you can bring Nulberries and equip the Coalescence skill to get some extra stats.

  • Considering Alatreon's high damage output, Health Boost 3 is highly recommended 

  • Traps and Meat will not work on Alatreon since it is an Elder Dragon

  • 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 its Active element, but it is significantly less potent than other elements, it becomes good if you have high damage uptime on Alatreon.

  • 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, if it doesn't hit one of the four big rock formations on the edge of the arena, it will simply not registers other walls and run into them without slamming. Alternatively, Alatreon can be flung out of the air at any time with the same effect as wall-slamming him, but that requires it to be flying.

  • Alatreon tends to target Hunters that are incapacitated in some way, such as being stunned or under a blight effect.

  • 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.

  • Alatreon has the highest HP of any solo intended Monster in the game (Safi-jiiva and Kulve Taroth are always scaled for 4 players and thus do not count), despite this it is not a bad idea to hunt it alone because its elemental damage threshold is very low when solo, and it is possible to brute force him into a kill by dying twice to the novas and doing enough damage to kill it before he does a third one.

  • 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, Alatreons Power has been contained enough at this point to make the Attack survivable.

By breaking Alatreons horns after it 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 its 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 its horns a second time.

  • Unless the group uses mostly Dragon, Thunder or Water weapons, Eliminating Fire Active or Ice Active 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 Elimintae Fire Active from the Rotation.

Going blindly for the horns can be detramental to the hunt! If you fail to break Alatreons 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 it's power in this Stage. Once it switches to Dragon again, you may contain Alatreons power once to survive the Escaton Judgement. But, if you break the horns, Alatreon will SWITCH BACK TO ICE NEXT! The horns should definitely NOT be broken in this case!

Surviving the Supernova (Escaton Judgement)

  • Alatreon's Ultimate Attack that can lead to a complete Teamwipe. It is indicated by the entire Arena filling with Frost of Fire and the Sound getting notably muffeled. This time should be used to heal to full health. After roughly five seconds, Alatreon releases a massive, arenawide 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 delivered through chip damage, meaning no stagger or Knockback (and therefore no I-Frames)

    • To make surviving the Supernova easier, all players should get together and place down their Health Boosters at the same spot, since they stack. Lifepowder and Dust of Life can be also be beneficial.

    • If Alatreon performs a full-power Escaton Judgement and you don't have 5 faints left for your 4 man group of randoms, you can use the time to Abandon the Quest and get all your consumables back. This should however be the absolute exception!

  • The Damage the Attack deals is dependant on how many times Alatreon has been KO'd due to elemental damage prior to the supernova. This counter resets after every Supernova!

    • 0 Times: You die. There are no skills, armors, or tools that will help you survive. The supernova deals over 400 damage in 5 seconds. No healing can compete with that. (If you're with an extremely coordinated team with the right skills and using items in a very strict window, you could technically survive. Team Darkside has made a video showing it's possible. However, most people probably do not have a coordinated speed run team playing with them.)

    • 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. Very hard to actually achieve in a group, but manageable solo if you have extremely high elemental damage.


Best Skills for the Fight against Alatreon

  • Health Boost 3: Extremely useful considering Alatreon's high damage output.
  • Blight Resistance 3: All Alatreon attacks are elemental, and can inflict Blights, this skill eliminates a huge part of the hassle of this fight.
  • Stun Resistance 3: Alatreon can stun very easily, and considering its very high speed and combo potential, a stun very often leads to death.
  • Coalescence: If you don't care about blights or can't be bothered to fit Blight Resistance 3 into your build, this can be a great boost to your stats.
  • Agitator: Alatreon stays in enraged state for a very long time, making this skill very good.
  • Partbreaker: Makes breaking the Horns and Tail easier, but the Horns already have very low hp.
  • Speed Eating: Can be useful if you're getting hit a lot and want to get back into the fight faster. Can also be used to survive a weakened supernova by using a single Mega-Potion, if you have Health Boost 3 and are full hp when Alatreon does its supernova, a single Mega Potion will let you survive, although you will be very low hp after that.
  • Wide Range: Can be extremely useful if your allies tend to get hit a lot, or if you don't trust them.
  • Fortify: Mainly useful if you intend to bruteforce Alatreon by ignoring his elemental damage mechanic, this will make it easier to kill him before he can do a third supernova.


Best Weapons to use against Alatreon

Dual Blades

The undefeated champion of elemental damage, which is crucial for a successful Alatreon hunt. The best option are the Kjarr weapons, fully augmented for maximum elemental damage. The low commitment attacks will also help in avoiding Alatreon's onslaught. The best pick for soloing Alatreon and almost necessary in a group.

Insect Glaive

Good elemental damage, fast attacks, "easy" mounts. The insect glaive is a great pick. Do NOT spam aerial, stay on the ground. 

Sword and Shield

Again, elemental damage is your friend. Also makes for a good support weapon and makes mounting Alatreon a lot easier. The Block might not be strong but could still save your skin. A weapon that is good in every category.


Ranged elemental DPS. The unlimited Ammo is the reason it is this viable against Alatreon, since you cannot restock Ammo without carting.

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.

Long Sword

Overall pretty moderate elemental damage, but a good long sword Player can deal a lot of damage relatively safe.

Charge Blade

A comparatively good shield and power-element phials will help against Alatreon

Switch Axe

No shield but more DPS than the charge blade. Again, make sure to use power-element phials

Great sword

Not recommended since great swords have very low elemental damage. There are great sword speed runs. However, the elemental damage required to knock down can be extremely difficult to achieve unless you're a seasoned player.


Like great sword, it has comparatively poor Elemental Damage unfortunately.


Like the above two weapons, they lack elemental damage and won't be very effective.


Elemental bowguns work great. However, remember you cannot switch weapons or restock ammos unless you cart and go back to camp. So naga set or razor sharp charm will be necessary unless you’re soloing and plan to cart to restock. Bowguns are relatively safe but one hit from Alatreon will likely cart you. Guns with both fire and ice elemental ammos will be better than one element alone unless you can break horns reliably during dragon phase.

Best Armor Sets

Teostra +

Best suited for dual blades if you do not like the protective polish / item prolonger play style (Teostra set will deal less damage but you don't need to sharpen as often). It's just really good in general, especially since you only need three Pieces for Teostra technique and therefore have two left for other sets. Like two pieces of Raging Brachy +


Best elemental set with Kjarr weapons. Gives lots of damage 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.

Kulve Taroth +

The ultimate Support set. Free Meal Secret, Guts, Lots of Slots. Combine with a Wide range charm and a Hunting Horn / Sword and Shield for the best Support.

Silver Sol

It will likely be useless if you have Kjarr weapons. Kjarr weapons are best paired with Safi set. However, it is viable for non-Kjarr weapons. Vastly inferior to Kjarr weapon + Safi set bonus. True Critical Element will amp up your Elemental Damage. This will consume 4 Equipment Slots though (3 if you manage to get Silver Sol on your Safi-Weapon).

      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

                    No need to fight the blazing black twilight Alatreon. You just need to defeat the dawn of triumph Alatreon, That Alatreon has very little HP so I recommend soloing it. Also don't forget to be over master rank 24.

                      So I've heard the Special Assignment Alatreon you need to fight to unlock Fatalis is weaker than the base. Does anyone have the data on the differences between the 2? Like, comparatively how much health does the new one have?

                        Ok Alatreon I didn't want to do this (at all) but you leave me no choice (actually capcom gave me no choice). You can cart me twice, you can cart me 3x, you can cart me 10 times. But nothing is gonna stop me for experiencing the black dragon himself, Fatalis. So I will hunt you and.... I will kill you. So watch out Fatalis because I'm coming for ya armor!

                          2nd Gen: Tigrex and Rajang
                          3rd gen: Alatreon, Deviljho, Dire Miralis

                          ...I think this is it. I might be wrong though.

                            Guy's, he's not actually that hard if you have a team that knows what they're doing. At this point, seeing as how you've already looked him up to find this page, you probably know what to do. The problem is that, he's actually difficult to solo, since he simply target you, making it hard to land hits. He's actually really easy with people who what to do. It's very hard to find people who haven't beaten it, who actually know what to do. So, you'll have a hard time through most means, but, if you're like me, and you get VERY lucky via SOS flare, you can get a halfway decent team, and actually clap this *****. After that, you can post the event quest, and send out an SOS. Because only people who have beaten it can join. People who know what they're doing.

                            My point is, the first fight is by far the hardest. Once you beat him the first time, it's all downhill. You CAN do it. It is possible. Even if you're having doubts, you may as well. Or you won't be able to do Fatalis. All that hype you had will be wasted. Don't let it go to waste. Don't waste it. Don't.
