Fatalis (Black Dragon) is a Large Monster in Monster Hunter World (MHW). 黒龍ミラボレアス (Miraboreasu) in Japanese.


A legendary black dragon known only as Fatalis. Rumored to have destroyed a kingdom in a single night, and has taken its castle for a roost.

As Long as its horns are intact, overcoming its final form's breath attack may be impossible. Cannons and ballistae can topple it. Flinch shots when its flying or standing will lower its head.

Fatalis Details & Locations


Fatalis Combat Info

  • Immune to stun-iconStun.

  • Kinsect Extracts:

    • Red: Head (1)
    • Orange: Forearms (3)
    • White: Hindlegs (2)
    • Green: Tail
  • You can fight Fatalis after you've completed the Iceborne storyline (MR24), discovered the Guiding Lands, encountered Safi'jiiva and encountered Alatreon.

  • You will unlock this quest by first talking to the Excitable A-Lister near the start of Seliana. This will take you on a quest to defeat an Alatreon with much less health than normal. After you have defeated Alatreon, you will obtain the quest "The Black Dragon" as a special assignment.

  • The start of this quest is solo only. After taking down about 22% of his total health, a cutscene will play and multiplayer will permanently be unlocked for the quest, even if you return back from it.

  • The Special Assignment version of the quest allows for up to 5 carts, the Event Quest version (Fade to Black) only for up to 3. 

  • First Nova: Fatalis will do the first area wide flame breath after losing about 22% of his health. You can only hide from this in a shelter on the right side of the arena, which is the same area you ran to with your NPC companion during the solo cutscene. After this nova the back of the arena will be unlocked, which includes multiple more siege weapons.

  • Second Nova: Performed after losing 50% of his health. You can only survive this one by running at the gate in the back of the arena and pulling the lever before the big flame comes out. Fatalis will enter his 3rd and final phase after this one.

  • Third/Fourth/Fifth Nova: Performed when Fatalis has 38%/20%/5% health left. You need to run towards Fatalis in order to avoid it. Since the Nova is cone shaped, it is recommended to run towards the sides rather than the center to get out of it faster.

  • After the second Nova, Fatalis will have a glowing chest. During this phase he gains new attacks (of which one can pin you) and all of his attacks become much more dangerous.

  • Breaking Fatalis's head once will weaken the attacks in the 3rd phase. Breaking it twice will prevent him from using the most dangerous versions of his attacks entirely.

  • The arena for the fight has multiple siege weapons, including three cannons, two ballistae, a roaming ballista and the Dragonator. There are also two one-shot binders (one near the wall behind the roaming ballista and the other one behind the ballista on the opposite side of the arena) that can be used to restrain Fatalis. Note that Fatalis tends to focus any player trying to operate siege weaponry.

  • Fatalis will be knocked down up to two times if he received enough damage through siege weapons. The first knockdown will happen after 1000 damage, the second one after 3000 damage. Heavy Artillery will increase the damage from siege weapons making it easier to knock down Fatalis with the siege weapons.

  • Each head of the Dragonator will deal damage equivalent to 5% of Fatalis's total health. Note that the Dragonator hitbox is much bigger than it looks.

  • Flinch shotting Fatalis when he's standing on two feet will cause him to go down on all fours. Only in this position Fatalis can be wall-slammed.

  • Every second Dragon Pod shot on Fatalis will make him flinch and interrupt his current attack. Fatalis will naturally drop dragon pods throughout the hunt, but you can also make him drop them through clutch attacks.

  • Because Fatalis is the hardest fight in the game, it is not recommended to tackle it until you have access to a fully optimized endgame setup, if possible with health augment for melee weapons (only unlocked after MR100 for R12 weapons).

Recommended Skills

  • Health Boost: Fatalis hits extremely hard and several of his attacks can even one shot melee players.

  • Divine Blessing: See above.

  • Fire Resistance: Almost all of his attacks are fire based and inflict Fireblight.

  • Blight Resistance: Use Blight Resistance if Fire Resistance of 20 or above is not possible for your build.

  • Coalescence: An almost guaranteed damage boost provided you aren't immune to Fireblight.

  • Agitator: Fatalis stays enraged rather long, so this is a good damage boost.

  • Partbreaker: Makes it easier to break his head.

  • Heavy Artillery: Increases the damage dealt with ballistae and cannons.

        At time of writing, I have 68 successful hunts on Fatalis, most of them on duo, but I have atleast 20-22 solo hunts on him.
        If you ever come across this page, here are some tips.
        Assuming you haven't killed him yet and it's your first encounter, naturally, you won't have Fatalis set.
        What you can use is 2pc Golden Rathian (Chest, and Coil) that'll give you Divine Blessing 5.
        3pc Lunastra Set on the remaining parts, for the Tool Specialist 5.
        That will make the fight easier. Use the vigorwasp palico gadget, when you max it out, it gives a revive if ever you overcommitted or miscalculated your steps.

        For the fight tips:
        You can use the cannon on the first phase, but keep in mind, in doing so, that would mean you wont be able to knock Fatalis down after the first phase using the Gattling, since it would need 3000 dmg, you wouldn't reach that easily even with HeavyArt2.
        As a matter of personal preference, I'd rather not use the cannons, so I can knock him down with the ballista.
        The reason for that is, I'm a longsword main, most of the hunts, it's either I have red gauge or yellow after knocking him down, if you use the cannon, you'll have to build up from nothing, and you won't maximize the damage.

        Evade Extender is unbelievably underrated in this fight, it'll save you a lot of time trying to close the distance or evading the cones, and his gigantic breath.

        As much as possible, hit his head on the first phase whenever you can, the best time to do so is when he does that long strafing fire breath while he is stepping backwards continuously.
        For his moveset, just try to fight him every time you feel like, that way you can at least memorize his pattern, his hitbox is extremely janky, so be mindful not to overcommit

          Just your perfectly average CASUL passing by:
          After a couple of nights of fighting against the clock, the game finally let me carve this wacky lizard with just ~8 seconds of time remaining.
          I just don't understand what these clown developers were hoping to achieve with this BS time limit... At least, I didn't have to grind Master Ranks and Guiding Lands for augments.

          It may sound amusing to you, but in the last 3-2 minutes of the fight, I got so nervous - I straight up stopped feeling my face and arms. Thought I was about to have a stroke. That was rough. Even though, to be brutally honest, I'm kind of fed up with living - that would've been a fairly silly way to kick the bucket. Heheheh!

            Abnd dead, finally took him out all by myself, only 2:35 left on the clock. What a fight, thou I chessed the heck out of it.

              Holy sh*** ran out of time after the fifrh firebreath, and a topple with a full TCS, meaning he probably had around 2.5k hp left. But the kicker is that I put him to sleep un front of the dragonrazor, but accidentally fired a sticky which wake him up before I could pull the lever.

                  Hello, some tips I found were that usually the sides and back are safe and I recommend using a weapon that can block. If your in multiplayer you go for the cannons for some free 1.5k damage (if most hit) I also used the MR kulave tarroth armor so I was immune to fireblight. His attacks are hit like a truck and some attacks are super hard to avoid like the breath sweep to blocking help
                  You don’t have to believe me, I’m not some monster hunting expert, but these are some tips I found usefull

                    Alright, I've just managed to down him for the first time, and gotta say... WHAT A FIGHT. Jesus, what a brilliant design, what a thrill, and the music, oh dear, THE MUSIC. This right here is one of my favourite bossfights, and I don't mean only in the MH franchise. God damn well done.

                      can someone explain me wtf just happened with my fatalis hunt? this was my 23rd solo hunt and after 4th nova he keep spamming the glowing chest pin attack. I had 2 carts remaining and after second head break(~20% hp left) he will do a ground fire sweep then pin and repeat it on a loop, i survived 5 consecutive pins but then i run out of max potions and eventually failed the quest. Previous runs were normal only ever got pinned 3 times in 3 different runs. This hunt has scared me for life.

                        Now imagine in a future Mh game we gotta fight (it will never happen but just imagine) A Frenzied, Hyper, arch-tempered, apex WHITE Fatalis in just 40 min. (now i know this sounds absurd knowing elder dragons can't get any of these things except arch-T, but still IMAGINE!!!!.
