Wraith

„A Wraith is one of the most dangerous Ghosts you will find. It is also the only known ghost that has the ability of flight and has sometimes been known to travel through walls.”

—The Journal^[src]

Wraiths are one of the twelve types of Ghosts that can be encountered in Phasmophobia, and the second ghost described in the Journal. Wraiths are best known for being able to "fly", indicative of them typically not producing footsteps while moving or teleporting to players randomly. The lack of footsteps and ability to teleport is the only thing that sets Wraiths apart from most ghosts, however, a common misconception is that they can travel through walls and see through doors. This information is false, despite the Journal's odd wording of a Wraith's abilities that would say otherwise.

Strengths and Weaknesses

Strengths: Wraiths almost never touch the ground, but this does not apply to the ghost model. Because of this, footprint sounds from a wraith will be rare to non-existent, and they can travel directly through walls doors without having to open them.

Weaknesses: Wraiths have a toxic reaction to Salt. If a Wraith comes into contact with a pile of salt, Ghost Activity will significantly increase.

Power

When a Wraith uses its power, it will teleport to a spot within 3 meters of a random player, creating an Interaction EMF. This is possibly what is meant by "traveling through walls" in the Journal. Be wary of this ability as it can sometimes throw you off and make you think the ghost room is somewhere it's not.

Additional Notes

Although Salt can make a Wraith stop attacking according to the Journal, nothing can really stop an ongoing Hunt.

The Wraith will hover without touching the ground for long periods of time, but it occasionally takes steps on the ground. In other words, a Wraith can still be tracked with Salt to some degree. Wraiths can step on and disturb a pile of salt, but they will not leave green Footprints. If Salt is placed in a doorway, a Wraith will most often fly over the Salt, leaving a hand print on the door that can be seen with a UV Light. However, this is not guaranteed, and it may result in a glitch where the wraith will enter its hunting phase and never stop.

Strategies

If you are struggling to get more Objectives such as "Witness a Ghost Event" or "Capture a Photo of the Ghost", you can try placing Salt. When the Wraith steps on the salt, you can have a higher chance of activity and a higher chance to complete the objectives.
