The titular medallion is a gift presented to young Nicole Elmi. Once the girl places the gift around her neck, she is possessed by the spirit of a dead child who was a murderess.
The Night Child (1975) is a supernatural film. Yet, very, very little gore. Infact there's no excessive gore at all. For horror movie lovers of 70s Italian this is filmed beautifully. The Director, D.P. and Location Manager plus Actors did their jobs superbly. It's filled with breathtaking Italian countryside, that of England including amazing paintings in Italy that are part of the story. The Night Child is a highly underrated and overlooked horror masterpiece.
There are vintage special effects of traveling mattes for certain scenes where people are falling. And done very well for the time. A scene with a person on fire yet not very intense. Therefore, this question is a matter of opinion.
This is one of those films where the main character is making a movie. Later he and the studio editor have to view some footage of the film. Upon that you find that "shakey cam" then that's an opinion. Years ago we called that viewing for editing.
Definitely the character who falls to her death into the fast flowing water with rocks and a waterfall did. But there aren't any close-up scenes of bones being broken.
