Ghost-Touch is a dangerous condition caused by ghosts. When a person has been ghost-touched, they rapidly turn blue. After that, their internal organs begin shutting down, quickly leading to death, unless the person affected recieves an adrenaline injection to the heart.
Ghost-Touch is caused when a living being comes into contact with concentrated Ectoplasm. It is the most dangerous ability of malicious ghosts, except for the Poltergeist, which has no Ectoplasm.
