I think you’re very likely to invite random parasites, as this is weakly intended and not the way to go about this. As states by DarkestKnight, a petition isn’t the right tool for this jib, invocation is. Which you already decided you don’t want to do with Asmoday in your other post. Can I just ask Asmodeus for power - #129 by Mulberry
Which makes this part a HUGE problem:
If you get a parasite you don’t get an option, it will embed like a tick and you will have to force it out. And your psychic skills are not developed making this ore difficult. Symptoms are feelings of anxiety and dread, making bad decisions, being emotionally negative much more - angry and irritable, losing friends and family because they sense something is wrong, bad luck, losing jobs, money and wellbeing, getting robbed or mugged, getting sick until you can’t work.
It’s not worth the risk.
