Vaal Hazak is an Elder Dragon in Monster Hunter World (MHW).ヴァルハザク (屍套龍) in Japanese.

Vaal Hazak Details & Locations


Vaal Hazak Combat Info

  • Elemental damages: Vaal Hazak emits a fatal vapor, also called "Miasma", which it uses to hurt its enemies.
  • Weaknesses: Vaal Hazak is weak to mhw-fire-damageFire and mhw-dragon-damageDragon .
  • Moderately susceptible to blastBlastblight and stunStun.
  • Weapons with mhw-eldersealElderseal cause its Miasma to dissipate for a short time.
  • Head, chest, front legs and tail are weakspots.
  • Weakness signs: As soon as the Vaal Hazak is injured enough, it starts limping. At a certain amount of damage, it starts playing dead to collect Miasma for a powerful attack.
  • Combat tactics: Due to its ability to shorten your Healthbar, a meal to get your Health up to 150, Vitality gems for up to 50 more HP, and a couple of Max Potions and Nutrients would be best to take on a hunt if you want to slay this Elder Dragon.
    • Nulberries can get rid of the Effect of Miasma.
    • The above mentioned "playing dead" should be approached from behind, since after collecting enough Miasma, it will shoot out a beam in front of itself, which can sometimes be fatal.This attack can be prevented by doing enough damage to it before it can collect enough Miasma. This attack can be stopped with a flash pod.
    • Equipping 3 Miasma gems will completely negate its ability to reduce your health to half. You'll still take damage, but your health bar will remain intact.
    • In the area just outside its den, on the ceiling are two fangs suspended by vines; hitting them with a projectile will cause them to fall down. Hitting Vaal Hazak with these does a decent amount of damage, and also knocks it over.
    • Multiplayer sessions should be wary of its Miasma beam. If it detects a target far enough away from it, it may decide to use this attack. Given the beam's large area of effect and distance, it's very possible that unwary hunters may be caught up in the beam by coincidence.
      • This can also be triggered by your Palico or nearby monsters such as the Raphinos that appear just outside it's lair and the Girros within, even though he is not hostile to them. Confirmed in single player and VERY close up, he just spammed the beam attack for a while, any corroboration would be appreciated.
      • In certain areas the beam can be blocked by the locale, such as a boulder or a wall
    • Stay away from acid pools, as the combination of acid damage and Miasma damage combined drains health very quickly.
  • Resistances: The Vaal Hazak is Immune to mhw-water-elemental-damageWater and has a relative high resistance to Poison, Sleep and Paralysis with only 1⭐
  • Vaal Hazak's mhw-dragon-damage_sDragon  weakness only applies to wounded body parts while its mhw-fire-damage_sFire weakness is always active.
  • The general tactics against Vaal Hazak is staying on its two sides (since it only has one breath ability that can attack sideways), maintaining a relatively close distance (since it has long distance reposition abilities that can put you in a position where it is impossible to be out of the line of fire of its breath), and keeping in mind that its charge abilities are (somewhat) wide and long.

        the wings do damage when he does a jump attack. THE WINGS! Then I block all of his attacks just fine only to be one shotted by one of his rush moves (I stay behind him!) or his miasma burbs (shield up...). Why exactly when it is 99 times no problem at all? Nobody knows... I can handle him fine now, got everything I need from him but these random sudden deaths totaly out of the blue are a bit annoying tbh.

          I'm featuring the Rotten Vale in a DnD oneshot. Here's what I got so far. Note that I don't plan on having them face Raodobann or Great Girnos and its for a level 20 party. It's also gonna be my first time being a DM. Anyways let me know what you think and sorry for the wall of text. Girnos stats! HP: 50 Strength: 11 Dexterity: 12 Constitution: 12 Intelligence: 4 Wisdom: 5 Charisma: 0 Slash: the Girnos slashes at a target, dealing 1d10 slashing damage on a hit. Bite: the Girnos attempts to bite its prey, dealing 1d6 piercing damage on a hit. If hit target must make a Constitution saving throw, if failed target is paralysed for 2 turns. Odogaron stats! HP: 1200 Strength: 19 Dexterity: 20 Constitution: 18 Intelligence: 0 Wisdom: 0 Charisma: 0 Resistances: Fire, Water, Poison. Weaknesses: Cold, Paralysis. Bite: the Odogaron attempts to bite for 3d8 piercing damage. Slash: the Odogaron slashes at its prey dealing 4d10 slashing damage on a hit, if hit target must make a Constitution save, if failed, target is now bleeding for 1d10 bleeding damage every turn for 4 turns. Pounce: the Odogaron leaps at it prey, knocking it down on a hit, and deals 3d8 piercing damage until knocked off. Odogaron will continue to attack the pounced party member until it is knocked off, the pounced target succeeds a Strength throw, or the target is dead. Tail Whip: the Odogaron slaps enemies behind it with its tail, dealing 4d6 bludgeoning damage on a hit. Roar: the Odogaron can use its bonus action to roar, all humanoid creatures within 30 feet must make a Constitution saving throw, if a creature fails that creature is stunned until next round. Vaal Hazzak! The Corpse Coat Dragon stats! HP: 3482 Resistances: Lightning, Poison, Sleep, Paralysis. Weaknesses: Fire. Strength: 20 Dexterity: 20 Constitution: 20 Intelligence: 20 Wisdom: 20 Charisma: 0 Effluvium Beam: Vaal Hazzak breaths a beam of pure Effluvium in a 60 degree arc starting from its right. All targets hit make a Constitution saving throw. Targets take 4d20 necrotic damage on a failed throw or half as much on a successful throw. Effluvium Mist: Vaal Hazzak can disperse the Effluvium built up in its body into a mist covering 30 feet surrounding it lasting for 3 turns. Anyone in this mist must make a Constitution saving throw. On a failed throw, max HP is cut in half for 5 turns and take 1d6 necrotic damage for every turn they spend in the mist. Effluvium Mist Beam: Vaal Hazzak fires an Effluvium Beam at the ground, dealing 1d20 necrotic damage to anyone caught by it. This attack applies the effects of Effluvium Mist. Effluvium Drain: Vaal Hazzak can drain the Effluvium from any nearby creatures with the status "Effluvium Corruption", healing Vaal Hazzak for 1d12+6 for every creature drained. This move kills any creatures drained. Bite: Vaal Hazzak bites at its target, dealing 2d12 piercing damage on a hit.

            For those trying to get fangs and not sure of if you've broken his head, when it breaks the spine bones where the head and neck meet will be broken off. It will look sort of like a crater.

              weird how i dont see anyone commenting or showing off his palico armour set, like who wouldn't want a tiny cat skeleton warrior running around with you? oh and the fight is fine as long as you get something to counter the effluvia, the instant that is not a critical element, you can just go in and attack for almost you heart content.

                RE: Fangs. Using HBG Spreadshots and shooting entirely at his face [and nowhere else], even after head breaks + using Legiana 2 piece set [extra rewards] + being on an investigation managed to net me a fang on almost every kill. No clue how a melee user would be able to reliably farm them. It was slow and tedious but I was able to get about 5 per hour.

                  This page makes Vaal seem so much more threatening than it actually is. I just took a lvl 1 dragonbone bow and it did the job. It's miasma "beam" attack is the only thing you need to watch out for and it is very telegraphed. When he is about to do it run behind him and fire a couple dragon piercers from its tail to its head and just spam your shots get that elderseal proc'd on him. Take max potions, null berries, and such, and make sure you eat the first go around. It is stupid simple.

                        Complete joke with lance/gunlance. Just guard and poke him between his legs until he does his breath thing, move to his side and go to town with your best combos. Repeat until dead. Easy solo with Nergal Ram + Nerg Armor A

                          Been farming fangs using the long sword. Best way I've seen is hit his head as much as possible when he turns around and go crazy on him when he has no gas left or when he is getting gas. Killed him in 16 minutes, 10 seconds, used a lot of nulberries and potions

                            The Medicine skill is really useful for AT Vaal Hazak, either when you have support teammates or run a friendship build yourself. Having just 1 level is immensely helpful when you heal yourself or others heal you. Keep everyone alive, and ohana.

                              PSA for Arch Tempered Vaal Hazak;

                              Assuming his weapons are any indication he naturally deals Dragon Element, which ironically is one of 2 elements he's weakest against. Equip Dragon Res jewels (+20 & bonus +10 def) and take a veggie meal (15) in the canteen. It helps a lot if you have a build that starts out with a positive Dragon Res value.

                              When Arch Tempered Kirin was around, I made sure to have my Thunder Res above 40. At that point his 2 insane charged-up lightning bolt attacks stopped 1-shotting me, taking only about 40% of my HP. The same principle should apply to Vaal Hazak's elemental attacks.

                                  Took him out with Legiana armor. It helps keep your damage to a minimum fairly often and also would help you farm for the fangs with its luck boost. Especially great for mounters with an addition of increased air attack.

                                    I beat a 15 min investigation, solo. Use a small weapon, sword and shield, dual blades. I tried great sword, but I'm hitting the armored legs too much. Didn't make it in time. Small one, stick to the chest. Fire element or dragon. Be very aggressive. Took him down w one min and 9 seconds to spare.
