Her amity minigame is horrible and reliant on incredible luck. You'll either have to hedge your bets with a combo of Luke, Lafi Bedmountain, Incas, Edan and Kina in some order, or just spam greeting, which is going to take a massive amount of energy considering you need 500 amity for her 2nd quest.

Finished her game up to 500 amity in under 60 energy. It really isn't so bad. Use greetings strategically before 100 and 300 to save a bit of energy if needed

she is hot isnt she

She is located up in Western Guard Camp.

P.S: Currently a bug in the game in which she will not appear if you have completed the main quest storyline from the Black Spirit up to Kama pt. 2.

How can I get the knowledge of her under the category node managers balenos???

It's virtually impossible to obtain the letter you need to complete Jarette's Support. The instance of her that is supposed to be in the Western Camp is just simply non existent. And the instance of her in Heidel has no options to talk to her.
I sent the devs a ticket about the bug twice and only ever gotten a halfass reply telling me to just do other quests in the area. They don't think I already did that?
I've had to just come to terms that I will never, ever finish this quest line.
