This is an unpredictable LoRA. It can add realism to non-realistic models or add 2.5D/toon look to realistic models. It can do a lot, but your best bet is to look at the samples. It can produce mature/NSFW themes, but only if instructed to do so. Trigger words aren't strictly required, but they certainly help:
zerthicon, strellis, ithrion, vaelith, shadowian
I've provided a text file with all of the training tags.
Depending on a model, you may need to ramp up the triggers up to 5 or keep them around 1. I've provided some XYZ plots.
Q: Do I need this LoRA?
A: Only you have the answer to that question.
Q: Why do you always put pictures of naked women?
A: Because I'm a filthy old bastard.
That is more or less all there is to it.
Have fun, enjoy, be happy and share your work.
