Countermeasures against Vaal Hazak

Recommended Weapon Element and Armor Skills

Recommended Weapon Element
Dragon Weapon	Vaal Hazak is weakest against dragon...
Fire Weapon	...and fire! Choose whichever weapon is stronger for you.
Recommended Armor Skills
Effluvia Resistance	Vaal Hazak can give you Effluvial Buildup, which acts like the miasma in Rotten Vale. He can also halve your health pool. Putting Effluvia Resistance to Lvl 3 can prevent this.
Effluvia Expert	In the meanwhile, fighting with Rotten Vale's miasma affecting you can be annoying. Get rid of this worry with Effluvia Expert.
Health Boost	If you cannot build Effluvial Resistance, having your health pool maxed out is indispensable.
Earplugs	Vaal Hazak has a big roar, so getting Earplugs Lvl 5 would be immensely helpful.

How to Beat Vaal Hazak

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

Building Effluvia Resistance

Since 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 Vaal Hazak. Using these rocks will not only take a huge chunk of 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 Vaal Hazak's attacks can hit multiple times and it can instantly kill you if you are wearing a Rocksteady Mantle. Some of 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

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 Vaal Hazak, immediately move to 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 Vaal Hazak roars or enrages

Which Part to Focus

Once you start the hunt, 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 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 Vaal Hazak can release. If 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

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

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