All Anomaly Types and Counters in Night at The Infirmary (Roblox)

Anomalies are the real fail condition behind most bad runs because they pressure your Sanity, not your HP. A clean run comes from treating every patient like a test: inspect them before admission, verify them again on the bed, and react the moment their behavior stops matching a normal patient.

Sanity, Reject, and Wooden Crucifix rules

An anomaly does not directly damage your character’s health. The danger is that it can trigger jumpscares, and each jumpscare can cut into your Sanity. Once Sanity reaches 0, the run ends automatically.

Your counter depends on where you catch the problem. If the patient looks wrong before you admit them, use Reject on the form and keep them out of the ward. If the anomaly is already inside, or it reveals itself during treatment, stop trying to finish the procedure and use the Wooden Crucifix.

Anomaly categories and fastest counters

The table is the quick read, but the important habit is consistency. Some anomalies are obvious before they enter the ward, while the nastier ones only expose themselves after you have already started treatment.

Patient check routine for each run

Inspect appearance and movement

Look for a twisted body, distorted limbs, faceless appearance, or walking that does not look normal.

Check the patient photo

If the file portrait moves, press Reject instead of admitting the patient.

Admit only clean arrivals

Let the patient into the ward only when the desk checks do not show a clear anomaly.

Connect the heart monitor

Check BPM before casts, IV work, or other treatment actions.

Scan with the Temperature Gun

Compare the reading against the normal 36-37°C range.

Listen before trusting them

Treat weird sentences, scrambled words, wrong names, or unnatural talking as a serious warning.

Watch the operation

If vitals spike, the room changes, or the patient warps out of bed, stop the procedure.

Reject or exorcise

Use Reject before admission and the Wooden Crucifix after an anomaly is in the ward.

Physical body anomalies

Physical anomalies are among the easiest ones to catch because the patient gives themselves away before you need tools. Watch their body shape and movement as soon as they arrive: twisted posture, stretched or distorted limbs, odd walking, and faceless appearances are all rejection signs.

If you notice the problem at the front desk, do not bring them to a bed just to be sure. Press Reject on the form and move on, because admitting an obvious visual anomaly only gives it room to start draining Sanity through scares.

Photo, BPM, and temperature checks

The file photo, heart monitor, and Temperature Gun form your main inspection route after the first visual pass. A moving patient photo is a desk-level fail: deny admission before the patient reaches the treatment area.

Once a patient is registered and placed on a treatment bed, connect the heart monitor. A reading of 0 BPM or an extremely high BPM means the patient should not be treated normally. Use the Wooden Crucifix instead, especially if the spike happens while you are already operating.

Skinwalker and shapeshifter behavior

Skinwalkers and shapeshifters work like the same threat in a run: they mimic something familiar enough to make you hesitate. They can appear as your Roblox avatar, your Roblox friends, previous patients, or ordinary-looking patients.

The problem is that devices may not expose them. Their BPM and temperature can look human, and Night Vision Goggles may show nothing strange, so speech becomes the strongest tell. Wrong names, scrambled words, broken sentences, and unnatural talking patterns are the signs to trust.

Their timing has one small wrinkle: they are tied to Night 2, with some runs describing them as starting on Night 2 and others as appearing after Night 2. Either way, once they enter the rotation, stop giving normal-looking patients a free pass.

Teleporting anomaly warnings

Teleporting anomalies are dangerous because they can pass the normal BPM and temperature checks at first. The warning usually comes from the room instead of the patient: ringing bells, flickering lights, shifting shadows, and monitor scale triggers all mean you should be ready to react.

The clearest reveal happens during the operation. If the patient warps out of the bed, the treatment is over. Continuing the procedure risks more jumpscares and heavy Sanity loss, so switch immediately to the Wooden Crucifix.

Event anomalies and Sanity control

Event anomalies are different from patient tells because some of their jumpscares can be unavoidable. You survive those runs by entering each stretch with enough Sanity to absorb a mistake or forced scare.

Use Sanity items when needed instead of saving them until the bar is already collapsing. After operations, clean patient beds so the ward does not fall behind and force you into rushed checks, because rushed checks are how a manageable night turns into a failed run.

Run-ending mistakes to avoid

The most common failed runs come from doing medical work before basic checks. Do not finish casts or IV treatment before checking BPM and temperature, and do not admit a patient whose file photo moves.

Also avoid trusting tools over behavior. If a patient speaks strangely, uses the wrong name, or acts wrong while the lights, bells, or shadows are misbehaving, treat that as the warning. Gambling with Sanity is worse than losing a patient to Reject or spending the Wooden Crucifix early.
