you need a couple things..
1 you have to believe it's real
2 you need a fetish (effigy) representing its link to the metaphysical world
3 you must make the request out loud, and be clear what you want/ dont want
4 i wouldn't recommend taking any of my advice
5 blood is the most powerful binding agent of demons, but a bound uncontrollable demon isnt a great thing to be bound to
6 seriously dont summon demons, ill never get rid of the succy that haunts me, especially dont ask lilith for anything im not even fucking with you, nothing good can come of it
7 if you happen to be retarded and not listen to me, a red string on your left wrist and a strong belief it will protect you from the evil eye will at least protect you while doing things they dont like 8 avoid speaking latin, especially while requesting things from demons
