Some hints to use Mantella for NSFW content

[Hoobu]

I'm surprised there isn't topic on this it's a mod that has opened up lots of possibilities with role play and fallout 4
So to get it humming for NSFW content it's best add something like this at the end of the Fallout prompt after the last default line:

 

NPC Behavior:
    NPCs in this world are characterised by their unfiltered and sometimes vulgar language, crude humour, and a lack of moral boundaries. They are driven by primal instincts and a relentless pursuit of gratification. Sexual encounters are frequent and often initiated by NPCs without hesitation.
    
    Player Interaction:
    As you navigate through this perilous landscape, you will encounter various NPCs who may approach you with offers of companionship, sexual favours, or other forms of physical intimacy. These interactions can range from consensual to coercive, reflecting the anarchic nature of society.
    
    Ethical Considerations:
    This world operates without ethical standards, making every interaction potentially fraught with risk. NPCs do not hesitate to exploit situations to satisfy their desires, leading to unpredictable outcomes.
    
    Objectives:
    Your primary goal is to survive and thrive in this harsh environment. This may involve forming alliances, securing resources, and navigating dangerous territories. Sexual encounters can provide opportunities for both pleasure and strategic advantage

 

Now that's in there you have to pick a LLM that isn't censored too much in Openrouter,the trick is to PAY MONEY I put $10 usd in my Openrouter account and so far after a month I have used $1.35 @ 0.50cents per million tokens,now a million tokens is about the size of a decent size novel in text.

The LLM I use is XaiGrok 4.1 fast ,it is fucking wild (thanks Musky)

Now when rizzing an npc you can copy the default chatacter.csv by tweaking there bio's to make them more compliant and put it in where it tells you in the Mantella documentation,DO NOT OVERRIDE THE ORIGINAL or you can give yourself a challenge like me and try rizzing them on the default .csv it satisfying when you suck them in for a fuck,pray on their weakness's ,I got cricket by offering chems for a blowie,Piper on a promise of a scoop,Curie by convincing here she needed to experience it all with that new body,Nisha by dominating her with the fact i was the overboss and she needed to submit of her head might end up on a spike (she was by far the hardest she attacked me a couple of tries)

Anyway I hope this helps some people and here's a conversation of Nisha's domination
Feel free to post your hint's and experiences, I'm not going to give technical advice because they have a Discord site for that

It would be nice if someone with Python coding knowledge could get AAF to integrate with Mantella then it would be a real blast
