Best Equipment and Items for Arch-Tempered Vaal Hazak

Arch-Tempered Vaal Hazak is no longer a threat in MHW Iceborne. But to be able to fell the Elderdragon in an easier manner, we listed all the necessary tips items, skills, and even sample armor builds to help you out against the Arch-Tempered Elder Dragon.

Best Skills

Effluvia Resistance	Without this skill, it is possible for you to get carted even with a good MR gear setup. This skill prevents AT Vaal Hazak from halving your max HP.
Tool Specialist	This is a great skill to have (much better if the secret is unlocked) to be able to spam those Health Boosters and Temporal Mantles.

Always wall slam the Daora for free downs, this will also open up opportunities to hit the head resulting in more downs (which we invested more skills for that time window instead of a QOL skill that won't even be used half the fight).

Best Weapons

Fire Elemental Weapon	Despite having 3 star weakness to both dragon and fire, Dragon actually doesn't work on unbroken parts. Make sure to bring fire weapons if you rely on elemental damage.
Weapons with Long Reach	Weapons like the Lance is great against AT Vaal Hazak. It allows you to snipe hard to target parts like the tail with ease.

Sample Armor Loadout

Weapon		Decorations
Shattering Flames II		Sprinter/Expert Jewel 4 Tenderizer Jewel 2 Augment:Recovery
Armor		Decorations
Head	Silver Solhelm Beta +	Miasma Jewel+ 4 Shaver Jewel 3
Armor	Silver Solmail Beta +	Sprinter/Expert Jewel 4
Greaves	Silver Solbraces Alpha +	Sprinter/Expert Jewel 4 Sharp Jewel 2
Waist	Silver Solcoil Beta +	Blaze Jewel+ 4 Miasma Jewel 1
Legs	Garuga Greaves Beta +	Expert Jewel+ 4 Tenderizer Jewel 2 x2
Charm	Blaze Charm III	none

Sample Build Skill List

Skills
Critical Eye 7	Fire Attack 5
Windproof 3	Critical Boost 3
Weakness Exploit 3	Marathon Runner 3
Slinger Capacity 3	Effluvia Resistance 3
Protective Polish	Clutch Claw Boost

	This is a modified Critical Silversol Build. We added in some Effluvia Resist to mitigate the Vaal Hazak's Effluvia aura. This will prevent you from losing your HP. The Health Augment will also keep your HP up allowing you to keep the offensive.

Best Mantles

Temporal Mantle	Easy way to dodge its attacks and it also allows you to flinch shot Daora much easier.
Health Booster	The most annoying part about fighting Vaal Hazak is its Effluvia. Not only does it halve your HP, it also does a steady amount of DoT. The HP debuff can be countered by Effluvia Resistance but the only way to counter its DoT is to outsustain it.

Best Items

Max Potion	Instant full healing.
Ancient Potion	More instant full healing.
Nulberry	If for somereason, you don't want to run Effluvia Resistance, make sure to at least bring Nulberries with you. A single pop will allow your health to return to its normal state but the HP removed will still need to be recovered.

Best Felyne and Palico Skills, Weapons, and Gadgets

Vigorwasp Spray	More healing to counter Vaal Hazak's DoT.
Felyne Insurance/Safeguard	More Cart limit.
Felyne Moxie	Allows you to survive a single lethal hit. Just make sure that you're away from Velkhana when the attack hits or not in an area with Effluvia or the damage tick will kill you. Not as recommended as Safeguard.

How to Beat Arch-Tempered Vaal Hazak

Arch-Tempered Vaal Hazak Tips
・Effluvia Resistance is essential ・Use the collapsable rocks in the first area ・Avoid using Rocksteady Mantle

Building Effluvia Resistance

Since Arch-Tempered Vaal Hazak covers himself with effluvia it is highly recommended that you build up your Effluvia Resistance to avoid taking chip damage and reducing your maximum health in half.
However, if you do not have any gears that can build up your Effluvia Resistance, you can rely on using Nullberry to counter any negative effects from the effluvia.

Using the Collapsable Rocks

There are two collapsable rocks in area 14 that you can utilize to deal massive damage to Arch-Tempered Vaal Hazak. Using these rocks will not only take a huge chunk of Arch-Tempered Vaal Hazak's health but it can also stun him for a few seconds giving you an opportunity to attack.

Using Rocksteady Mantle

Many of Arch-Tempered Vaal Hazak's attacks can hit multiple times and it can instantly kill you if you are wearing a Rocksteady Mantle. Some of Arch-Tempered Vaal Hazak's attacks can hit you multiple times until you cart, it is best to avoid using Rocksteady Mantle since it will prevent you from being blown away after taking the initial hit.

Miasma Breath

Arch-Tempered Vaal Hazak's miasma breath attack can cover the area which can be deadly if you are not wearing any Effluvia Resistance. Be sure to move away from the cloud and only engage when you are sure that it is safe to attack.

Moving to the Sides

Miasma Breath covers a large cone-shaped area in front of Arch-Tempered Vaal Hazak, immediately move to Arch-Tempered Vaal Hazak's sides to keep on attacking and to remain aggressive while avoiding damage from the miasma.

Changing Targets

・Attack the Head and the Tail at the beginning of the quest ・You can reduce the amount of miasma around a body part after dealing a certain amount of damage ・Breaking a body part will significantly reduce the amount of miasma in that area ・Amount of miasma increases when Arch-Tempered Vaal Hazak roars or enrages

Which Part to Focus

Once you start the hunt, Arch-Tempered Vaal Hazak will cover his whole body with miasma except for the head and the tail. Focus on attacking these parts and destroy them immediately to prevent Arch-Tempered Vaal Hazak from releasing miasma on these parts.

Reducing The Miasma

Dealing a certain amount of damage to a body part will greatly reduce the amount of miasma that Arch-Tempered Vaal Hazak can release. If Arch-Tempered Vaal Hazak manages to cover his head and tail with miasma, it is best that you focus on attacking the legs instead since they are the easiest part that you can reach with most of the melee weapons available.

Changing Patterns

・Arch-Tempered Vaal Hazak will only use the enhanced miasma breath when his body is covered with miasma. ・Arch-Tempered Vaal Hazak will move faster with less miasma around his body

If the amount of miasma that covers Arch-Tempered Vaal Hazak decreases, there is a higher probability that he will perform a quick counter-attack.
