Where To Find Viper Napuatzi
You will encounterViper Napuatzi in Utzaalduring the ‘Legacy of the Vaal’ quest near theend of Act 3. She isa mandatory bossthat youmust defeat to reach Aggoratand enter The Black Chambers.
Utzaal is an Area Level 43zone, which means you should besomewhere around Level 50 before fightingViper Napuatzi.

She is highlyresistant to Fire,Cold,Lightning, andPhysical damage. If you are not using a Chaos-based skill, try toinvest in some form of Elemental Penetration.
Preparation And Battle Tips
As forher attacks, most of themdeal Chaos damage, which can be very deadly if you do not find a way to mitigate it. Here are a few ways to do so:
The fight takes place in a small arenathat gradually shrinks over time. Because of this, we recommendat least 20 percent Movement Speedto dodge her attacks.

Also, since no monsters spawn during the encounter, it is verycommon to run out of Flask Charges. This is why we recommend having the ‘Gains # Charges Per Second’ mod on your Flasks. This isnot absolutely necessary, but it is a nice quality-of-life bonus.
Try toburst her downas quickly as possible. The last thing you want is tolet her spam all her abilitiesthroughout the encounter. Unless you may nuke her instantly, the fight issignificantly harder for a melee characterthan a ranged one.

Endgame builds likeSpark,Lightning Arrow, Attribute-stacking etc. can easily trivialize the fight if youinvest in some Chaos Resistanceon your leveling gear. Moreover, skills like theTempest BellandFrost Wallcan keep her in one place, allowing you to deal damage until she is dead.
If you are unable to get Chaos Resistance, your other option is toget as much HP as possibleto brute force the fight.

The fight againstViper Napuatzi is a dodge-check,if anything. If you are able totime your dodges perfectly, you should have little tono trouble with it.

Poison Darts
She locks onto you andfires a barrage of poisonous projectiles. This attack ends with her throwing multiple projectiles in a cone shape.
The best way to avoid this attack is tokeep moving in any direction.

It could take a while to get the hang of this attack, but it is not as complicated as it seems. Ideally,you should dodgewhenever you see the tip of thespears glow green.
If possible,pay attention to her dialogues. She says aspecific set of dialogues before particular attacks, which can help in some cases.
After defeating her, thesoldiers in the arenawill turn theirattention to you. Be careful not to get overwhelmed anddefeat them to complete the encounter.
