That skill seems like a Catholic version of exorcism.

There is also the shamanistic method found in GURPS Ice Age.

There are real-world exorcists, though they tend not to be Catholic-oriented. There's even a documentary TV series about them from some years ago.

There are also modern shamanistic exorcists and depossessors. In my experience, they prefer to do a compassionate depossession, where they arrange for the possessing spirit to go get what it really wants somehow other than possessing the subject.

In games, I don't know that I've never seen the Catholic exorcism method used.
