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.
  • Evening star quest: Alatreon will start in fire element. Weak to ice (3 stars), and thunder (2 stars). Immune to fire.
  • Death star quest: Alatreon will start in ice element. Weak to fire (3 stars), and water (2 stars). Immune to ice.
  • Deals mhw-dragon-damage_sDragon, mhw-ice-damage_sIce, mhw-thunder-damage_sThunder, mhw-fire-damage_sFire and mhw-water-elemental-damage_sWater damage, and can inflict ailments of each element.

  • BRING ELEMENTAL WEAPONS! Dealing elemental damage is the most important part of this fight.

  • Weak to mostly Ice and Water damage in fire form.

  • Resistant to all ailments and the element it is using.

  • Kinsect Extract:

    • Red: Head

    • Orange: Legs

    • White: Wings

  • You can obtain a Shiny Drops by breaking its horns, performing a succesful Wall-Slam and by using the Plunderblade

  • Eat an Elemental Defense (L) Meal (6 Vegetables) before the fight.

  • Blight Resistance 3 should help against the various blights. Bring Nulberries and equip the Coalescence skill to get some extra stats.

  • As always, Health Boost 3 is recommended

  • Alatreon is an Elder Dragon, so no Meat or Trap will work

  • How to survive the nova: There's a very small window where you can use a health booster / Aster Jerky and spam other items like Dust of Life and maybe survive. Success rate is rather low so the best approach is to prevent them by dealing significant ELEMENTAL damage to the monster.

  • Once Again: USE ELEMENTAL WEAPONS. Particulary Ice and Dragon are your best picks. Ailments are hard to trigger and Raw Damage yon't protect you from the Supernovas!

  • Ice is pretty great until Alatreaon switches to Ice-Mode. To avoid this, break its Horn after Alatreon switches Elements for the first time (from Fire to Dragon). Once it went from Fire to Dragon again, You will need to break the second Horn, or Alatreon will switch to Ice-Mode next.

  • Save your Slinger-Bursts until Alatreon switches Elements. Knocking down Alatreon at that point is extremely important since you need to break its horn to avoid Ice-Mode.

  • Also make sure the Slinger Burst hits one of the four Larger Rock formations at the outer Ring of the Arena, since the other walls will not trigger a Wall-Slam.

  • Despite the game's recommendations, fighting Alatreon solo is not a bad option. Its HP is "only 52.500", it gets KO'd by Elemental overload much easier, and you can faint in two of the Supernovas without failing the Quest.

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


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.

    • Dodging, including the Superman-Dive, and all mantles are useless. 

    • The damage is delivered through chip damage, meaning no stagger or knock back (and therefore no I-Frames)

  • 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.


Best Skills for the Fight against Alatreon

  • Health Boost 3: You know the drill.

  • Blight Resist 3: It should be mandatory. All Alatreon attacks are elemental and will give you blight. Otherwise you will run around 90% of time eating nulberries.

  • Stun Resist 3: Three hits in short succession are enough to stun, most likely leading to your demise. Bad. Get Stun immunity.

  • Coalescence: If you don't have Blight Immunity (WHY?), you might as well make something of that. Since you will be constantly recovering from something, Coalescence is pretty much a permanent boost. Coalescence + blight resistance 2 is viable if you're confident to not get hit by Alatreon.

  • Agitator: More Crits

  • Partbreaker: Makes breaking the horns easier, but is mostly useful for severing the Tail.

  • Speed Eating: Not necessary at all unless you're running a healing build. Supernova can be survived easily without it (only if you knock down Alatreon).

  • Wide Range: If your Build allows it, swap your Talisman for a Wide-Range V Talisman. Trust me, your team will thank you for it.

  • Fortify: You don't want to cart, but if you do, might as well come back stronger.


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 elemntal 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).

      Can he still be knocked out from elemental damage during the 5 seconds before he unleashes judgement, or does it do nothing?

            The horn can only be broken when it is in draco mode only in that mode that is to prevent it from going to its third elemental mode, I do not know why they say they break it when it is in ice or fire mode. And the worst thing you can do to break his horn when the elemental mode he was in was that his weapon was disadvantaged if you carried so much ice or fire. And I mean if they couldn't stop her from going into her third elemental mode.

                      The fight itself is fun once you get use to it, but the DPS check and super move is unoriginal. While it has a different mechanic and harder to "stop" it, it still the same idea. We already have Safi, behemoth, ancient leshen, lunastra and Teostra that have a supernova or onehit kill and it's boring. Wheres the flavor. But I like the fight and I'm just nitpicking

                        I slayed Alatreon many time now but only after dying countless times before. Here are some advice for those struggling:

                        1. Bring weapons able to dish high elemental damage like DB, Sns, IG or even CB with power element phials.
                        2. Bring either Ice of Fire weapon depending on the starting element of Alatreon. I personally used Alatreon LBG as it has both the fire and ice ammo. In fact I crafted this weapon by using the materials dropped during my numerous failed attempts. I also defeated it by using Kjarr SA and DB. Remember to always bring opposing elemental weapon to Alatreon starting form.
                        3. However, you can also bring dragon weapons as they will not be useless if you fail to break Alatreon horns. (See below)
                        4. Bring plenty of heal and ways to craft more as forecasting is not an option here.
                        5. Stack skills such as health boost, divine blessing, part breaker (for horns and tail) and blight resistance.
                        6. Eat for elemental resistance L and skills such as feline safeguard of feline insurance.

                        How to fight:

                        1. Dish out maximum damage while either in fire or ice active mode until you topple Alatreon.
                        2. After first elemental switch to Dragon active, focus on breaking Alatreon horns by slamming it against the wall (only in specific areas) or flinch shot it while in the air. This will prevent it from switching to its other elemental form. (Ice active if started as fire active and vice-versa)
                        3. After first nova, Alatreon will revert to its starting element. Again, dish out elemental damage until you topple it. Focus on breaking its horn while it is in dragon active mode as failing to do so will trigger its opposing element after the second nova and this may lead to weapons being useless in reducing the third nova damage. (This is why dragon or even water element may be a safer bet as they are not useless against any of Alatreon's form)

                        This is pretty much it. Alatreon is not overpowered or broken as some says. I carted many times but I realized that this monster was designed in such a way that it forces people out of their comfort zones. I initially used raw weapons which led to instant cart at the first nova. The key is elemental damage and the rest is knowing how to evade and healing.

                          I cleared it solo using the Fortify skill. No elemental damage needed, just need to pump out enough raw dps to kill it before the 4th nuke

                            I can confirm that the handler is a liar. When you break the first horn, she says "Looks like it can't switch into ice form anymore!". When you break the second horn, she says the exact same thing again "Looks like it can't switch into ice form anymore!". Then he switched into ice form and deleted me from existence.

                              I have to question the details on this page saying to use ICE specifically. When you're in the game, note that you can change the details on the affinities list. Ice is only good when Alatreon is in FIRE mode. There are 3 modes. I recommend Dragon, Water or Thunder. Those 3 are always positive. Ice and Fire will be a big ol' 'X' depending on the mode.

                                I think everyone should take the things written in the page with a grain of salt.

                                If we could give the hunters some time to collect more concete data instead of hating on them for "inaccuracies" that would be great...
