If there was a spell or ritual that existed in a movie/series/anime/etc. And of course the given spell/ritual would be greatly explained on how it works in that universe and the meaning it has and pretty much everything. Now, let’s say that the movie/series/anime/etc. is really famous and really many people know about that ritual and know perhaps a little bit more that the basics on how it works because they like it.
The spell/ritual isn’t from our world but if it’s that much accepted and powered by all these people’s thoughts in that way, could a magician make the exact same spell/ritual in the exact same way and make it work successfully?
