Behavior: A devourer of fear, these ghosts have been shown to haunt their prey, feasting off their nightmares to grow stronger. Their general behavior seems to mimic that of a Revenant, slowly stalking their victims until it is sufficiently strong to chase them down.

Behavior: A wisp of piercing cold, these seemingly tame apparitions aren't so peaceful. According to the collaboration of our Outwatch pages generally the Wraith likes to lurk very close to the walls to catch unknowing victims off guard, and only a pinch of salt can save the unfortunate.

Behavior: Full of hatred and dissatisfaction, the touch of these sin-bound spirits causes deathly ailments. Generally, these ghosts linger near former possessions, positioning themselves in such a way that it is impossible for Seekers to escape their piercing gaze.

Phantom: Flickering in and out of sight, the song of this Being is not so easily tracked.
Movement: 3
Special: Can teleport 2 spaces at the start of its turn. These 2 spaces can be through walls, and can’t be picked up by detection equipment.
Cleansing Ritual: [NAME] flickering shadow, your attempts to hide from your [DEATH TYPE] has tied you to the [BONE ROOM]. Leave no trace in this world.
Paranoia Bonuses: 30%>= Paranormal Paraphernalia doesn’t detect it. 40%>= Can teleport to any unoccupied room at the start of its turn before moving. 60%>= Can teleport 3 spaces at the start of its turn. These 3 spaces…
Behavior: Information on this spector is spotty as its haunting song seems to come everywhere all at once. It appears to generally lurk in adjacent rooms ready to noose its obsession and often changes rooms quickly, rendering Ghost Detecting equipment useless.

Doppelgänger: A lack of identity during life has made it difficult to identify in death.
Movement: 5
Special: Select a ghost type and mimic those evidence rooms.
Cleansing Ritual: Trying to find yourself brought your [DEATH TYPE] in the [RECEPTION]. [NAME] you are sufficient, go home.

NOTE: When paranoia is reduced, if it goes past the thresholds lose the ability of that threshold and gain previous ability.
Behavior:Difficult to identify, these tricksters play with dedicated Ghost Hunters as their evidences are never quite where it should be. These ghosts appear to have no set personality, shifting their behavior frequently.

Movement: 4
Special: During haunts, can move one insane seeker (for their movement) per turn. During search, for every insane seeker, it can get 1 space closer to sane seekers (if a haunt is started on top of a sane seeker they don’t immediately become insane).
