Avalintra, the Huntress is a mixed encounter - you could insert some social aspects, or some combat elements. She is a focused bounty hunter who is intent on getting the job done no matter the cost.
While there is a heavy fight aspect to the Huntress, there doesn't have to be initially. They're going after the same bounty, but that doesn't mean they have to be against each other. The party could easily work out a deal with the Huntress, where they're aligned on getting the bounty done. Consider having them work together. Maybe they work together fully without issue, or maybe Avalintra finds some reason to work against the party in the interest of getting paid. The world is your oyster!
Avalintra's fight is a fairly straight forward one. Open up with Weak Spot to put the party on their toes immediately. During a normal turn, use your action to hit them with a Chakram attack and Trapper Expert. Rotate through the traps to really give the players the feeling of variance in the fight. If for whatever reason she can't reach a target, use Javelin to close the distance on them.
If she misses an attack, or fails a save, use Primal Instincts as heavy flavor. Maybe she swings at a target, they dodge out of the way only for her to twist suddenly and hit them right in the side. Maybe it looks like she's going to get hit by a spell or attack only for her to last minute dodge out of the way, almost inhumanly.
Avalintra is an aloof bounty hunter, who has two very drastically different personalities. While she's on the job, she's quiet, direct, and focused near solely on seeing it through. Nothing distracts her, nothing will stop her, and she always gets her mark. Sure, she may toy with anyone who gets in her way, but only as long as it doesn't interfere with the job.
As soon as she has her quarry, however, there's a massive shift in personality. She's loud, outgoing, and is often seen drinking everyone else under the table. The village she worked the job for has one insane night of partying that is sparked mostly from the mood she brings to the watering hole. The next morning, however, she's up early and gone. Almost as if she was never there.
Avalintra has been a bounty hunter for a long time. She's an expert at tracking down and apprehending prey, but doesn't often sit around in one spot. Many villages have stories about "The stern, beautiful woman who breezed through town", but not many know her well.
Avalintra has wandered around for as long as she can recall. She came from a small village, that wasn't really eventful. When she could, she set off into the world to find adventure until she finally settled as a career bounty hunter.
Regardless of how you insert the Huntress into your game, music that hits a more wild note is what we have in mind for the mood. For any social aspects with the Huntress, we recommend the Eldain Theme from Thronebreaker. For combat, we recommend The Hunt Begins from The Witcher 3.
