Here is a thread about the intranquility spirit spell: Intranquility Spirit spell - everything you need to know
I cannot find the exact thread of evoking Sallos and Dantalion that I was looking for but if you type evoking Sallos or evoking Dantalion into the search bar something should come up. The basic principle is this you gaze at the demons sigil and chant their enn until the sigil starts to flash. Sometimes you will feel an energy and sometimes not. You make your request to the demon. This can be done as a petition if you wish
Hope this helps
It’s important not to lust for results. There is no best method to get this girl. What matters is your intent.
