How to Identify a Wraith and All Evidence
An EMF Reader will let you know when a Ghost is nearby and interacts with the environment around it. It has 5 different color coded levels which indicate the type of interaction that's taking place. However, only an EMF Level 5 will count as evidence and suggest that you're dealing with a specific type of Ghost.
Other possible Ghosts with EMF Level 5 Evidence: Goryo, Jinn, Myling, Obake, Oni, Raiju, Shade, Spirit, The Twins
To use a Spirit Box, you must be nearby (3m) or in the same room as the Ghost and the lights must be off. Then, you will be able to speak to the Ghost and ask it questions from four different categories - Difficulty, Location, Age, and Personal. 50% of the time, Ghosts will be shy and will only respond on the Spirit Box if there is only one player nearby. Not all Ghosts will respond, but the Wraith is one that will. If it does, you have found another piece of evidence.
Other possible Ghosts with Spirit Box Evidence: Mare, Onryo, Phantom, Poltergeist, Spirit, The Twins, Yokai
When mounted on a wall or the floor, the D.O.T.S Projector will cast a bright green laser grid made up of dots in the surrounding area. If a ghost crosses through the grid, their silhouette may appear as a faint, white figure passing through but is not a guarantee. The silhouette can also be seen through video cameras, so players tracking evidence such as Ghost Orbs from the video feed in the truck can also see this.
