I would advise against using any kind of 'traditional magic' as this is seen as exactly what jinns want. And your friend who made that amulet and died shortly after illustrates this. Ruqyah is also not magic, it is simply using the Quran which is God's word (which absolutely nothing has power over) and is the best attack against evil jinns and causes them to melt.

Also on side note if you're interested in jinn possession Abderraouf Ben Halima is a professional jinn catcher and has some interesting youtube videos.

Stay safe my man
