As I said, keep it simple.
I literally wrote that because I expected this question.
If you want pure sex, and lots of it, Sitri is more than enough.
If you want to learn how to get chicks and make them cum by dominating them, Belial.
If you want to get relationships and love, I’ve heard Beleth and Sallos are excellent for this.
The thing is, you aren’t taking into account the raw power these mighty spirits possess.
For example, Sitri.
Sitri is a damn DEMONIC PRINCE.
The titles aren’t just for show.
Belial, a DEMONIC KING.
Just one entity is more than enough for you.
My advise - since you want a seductive aura, contact either Sitri or Belial, and ask for a seductive aura to get chicks.
But, you have to do your own research.
Go and research - this is immersion into the spirits and their energies. As you research and find out more, you will know what to do.
And don’t think that combining the energies of 3 spirits will get you farther. It’s not just about the quantity of energy. For this operation, you need developed astral senses or really fucking good divination skills.
