The Oni is one of the few ghosts in Phasmophobia that gives itself away by how it looks during a hunt rather than by anything it leaves behind. It flickers far less than every other ghost, so instead of catching a shape between blinks, you get a near-solid model chasing you across the room. That single trait carries most identifications, and there is a second behavioural test that rules the Oni out without you ever risking a hunt.
Quick answer: An Oni stays visible for roughly 55–63 percent of a hunt, against about 31–33 percent for a standard ghost, and it can never perform the mist form (airball) ghost event. Confirm it with EMF Level 5, Freezing Temperatures, and a D.O.T.S. Projector silhouette.
The Oni blink pattern during a hunt
Every hunting ghost cycles between invisible and visible frames on a fixed set of timers. A standard ghost spends short bursts on screen and long stretches invisible, which is why hunts usually read as a stuttering silhouette. The Oni inverts that balance. Its invisible intervals are shorter and its visible intervals are much longer, so it reads as an almost continuous model with occasional flickers.
| Ghost | Time visible during a hunt | What you see |
|---|---|---|
| Standard ghost | 30.7% – 33.2% | Brief appearances between long invisible gaps |
| Oni | 55.3% – 63% | Sustained visible frames with short blinks |
The gap is wide enough to judge by eye. If you can comfortably track the model around furniture and keep it in frame for a second or more at a time, you are looking at an Oni. A Phantom sits at the opposite extreme, staying mostly invisible while hunting, which makes the two easy to separate in the same test.
Movement speed is not a tell here. The Oni hunts at standard ghost speed, so judge it purely on visibility and use footstep tempo only to rule out faster or slower ghosts.
How to trigger a hunt and watch the blink test
Waiting for a natural hunt wastes contract time and usually starts it while you are somewhere with no sightlines. Forcing one with a cursed possession puts the hunt on your schedule and in a room you have already picked.
Tip: On Nightmare and Insanity, where evidence is hidden, a video camera pointed at the loop you are running gives you a second look at the blink pattern once you are back in the van.
The ghost event that rules an Oni out
An Oni cannot perform the mist form ghost event, the ball of fog that drifts toward a player and vanishes with a hiss on contact. See one of those and the Oni is off your list immediately, no hunt required.
The catch is that a chasing event can also produce a hiss, and players regularly mistake one for the other. Four of the hiss sounds in the game belong to events other than mist form, and only a single hiss is shared between the two, so the audio alone is not decisive.
| Clue | Mist form event | Chasing event |
|---|---|---|
| Visual | Ball of fog moving toward you | Ghost model pursuing you |
| Ghost vocalisation | No | Yes |
| Footsteps | No | Yes |
| Doors in the room | Unaffected | Usually slam shut |
| Oni can do it | No | Yes |
Listen for the vocalisation and footsteps before you write anything off. If doors close around you and you hear the ghost, that was a chase, and the Oni is still in play.
Oni evidence: EMF Level 5, Freezing Temperatures, and D.O.T.S.
On difficulties that still show evidence, three readings lock the Oni in. Because the ghost interacts constantly, these usually come faster than they do for quieter types.
| Evidence | How to get it |
|---|---|
| EMF Level 5 | Carry the EMF Reader into the ghost room and provoke interactions until a reading spikes to 5. |
| Freezing Temperatures | Sweep rooms with the thermometer, or watch for your character’s breath fogging in the ghost room. |
| D.O.T.S. Projector | Place the projector in the ghost room or its doorway with a camera facing it, then watch the feed from the van for a silhouette. |
Set the D.O.T.S. Projector up early rather than saving it for last. The Oni’s high interaction rate means the ghost room is often obvious within the first minute, and an early placement buys you more chances to catch the silhouette on camera.
Activity spikes and the doubled sanity drain
Onis love to scare their victims as much as possible before attacking. They are often seen in their physical form, guarding their place of death.
The journal description matches the numbers. Whenever at least one player is within six metres of the Oni or standing in the same room, its activity increases by 30. Long stretches of silence while you are alone, followed by a burst of interactions once a teammate joins you, is a supporting clue worth logging.
| Behaviour | Oni | Other ghosts |
|---|---|---|
| Chasing event chance | 40% (60% with The Devil tarot card) | 20% |
| Full-form manifestation | 2 in 3 | Lower; often shadow or translucent |
| Sanity lost on ghost event collision | 20% | 10% |
| Mist form event | Never | Possible |
That doubled drain matters more than it looks. A couple of chasing events can drop the team to the hunt threshold well ahead of schedule, so bring sanity medication to claw the loss back, or move incense forward in your loadout and keep it on you rather than in the van.
Why an Oni test fails
Most bad calls come down to a handful of repeatable mistakes rather than bad luck.
- Judging the blink pattern from a doorway or a corridor, where the ghost passes out of sight for reasons that have nothing to do with its timers.
- Hearing a hiss during a chase and crossing the Oni off as though it were a mist form event.
- Never grouping up, so the activity spike that makes the Oni obvious never happens.
- Placing cameras too late to review the hunt footage afterwards.
- Stopping at behaviour alone on lower difficulties, where a Poltergeist or The Mimic can look similar until the evidence is checked.
You know the identification has landed when Oni is the only entry left unstruck in your journal and the end-of-contract summary names the ghost type you selected. If the blink test was ambiguous, run one more hunt with a camera covering the room before committing.
Everything that makes the Oni dangerous on the sanity front is also what makes it quick to pin down. It reacts to you being close, it manifests in full form more often than it hides, and it barely bothers to disappear once a hunt starts. Get one clean look at it moving through a lit room and the call usually makes itself.
