@DonGiovanni No, I saying that he should save it for when an evil spirit is about to take his life or cause malicious intent that would put him in a hospital if he didnt die from it. Those emergency situations. unless he has a batch of them, he really should not waste them. Might stuck that the neibour get possessed, but nothing life threatening or dangerous.
Its only mischief. The ghost has also clearly
been friendly with him, but he intended to use some
holy attack on her.. but in the end, its just a prank. so it didnt matter. Better finding out its a prank, than using it when your life is on the line lol.
