Ghost mines are invisible mines of Drudge origin that can only be detected with the All-Seeing Eye. They detonate when anything or anyone comes in contact with them. You can use the ASE to detonate them from a distance. They come in from Level 3 onwards. Strangely, their explosion cannot harm anything except the protagonist Michael Ford.
