Definitely the Ars Goetia, it’s by far the safest. Find a demon who’s noted as being truthful and faithful to the magician as they’ll probably give you the least trouble and go from there. Some advice:
Make the black handled knife as the grimoire instructs. This is absolutely not optional. If something goes wrong and you don’t have it, you’re fucked. I personally found ferric chloride to be a good way to get the symbols on the blade but most engrave them. There are a lot of articles floating around regarding how to address the blood issue so do your research and disregard anything that says to use your own blood. If you have a friend who’s a vet tech even better.
The lamens are not optional but paper does work. Most goets these days use nice “virgin” (ie new and unmarked) paper
Don’t be a dipshit and try to replace all the names of God and angel names with different ones. These are Abrahamic spirits so use Abrahamic names.
If the demon doesn’t deliver what you agreed to, fuck ‘em up.
NEVER EVER pay beforehand or provide offerings unless the spirit is specifically noted as requiring one (ie Paimon).
The Greater Key has a ton of information regarding the prep work. Use it, especially regarding pre-evocation purification rituals.
