Class
Doctor
Updated:
Sanity-on-cure — every correctly treated patient restores 1 sanity, plus bonus starting sanity at higher tiers.
Overview
Doctor is the sanity-on-cure class, priced at 900 Animal Coins from the lobby shop. Level 1 recovers 1 sanity per patient successfully healed; Levels 2 and 3 add bonus starting sanity on top of the per-cure tick. The whole class identity is sustain — every clean patient run banks sanity that absorbs the next ambient drain (Mass of Eyes uptime, Shadow Figure glances, late-shift wear).
Visually, Doctor is a light-orange deer-like creature in blue medical scrubs under a white consultation coat, with a black stethoscope, taped-bridge eyeglasses, and two muted-tone antlers. The design intentionally echoes Dr. Harlow, the hospital's supervising NPC — they are distinct entities (Doctor is the playable class; Dr. Harlow is the named NPC) but the visual link is deliberate. The 900-coin price point puts Doctor in the mid-tier expensive bracket; the per-cure sanity income generally pays back the unlock cost across the first 10-15 shifts of play.

Class Abilities
- Level 1: Recovers 1 sanity for every patient successfully healed with the correct treatment
- Level 2: Level 1 effect + bonus starting sanity at the beginning of each shift
- Level 3: All previous effects + additional starting sanity bonus stack
Pros & Cons
Pros
- ✓ Predictable +1 sanity per heal — scales naturally with shift length and patient throughput
- ✓ Mid-tier price (900 coins) — accessible after the cheaper specialist unlocks
- ✓ Bonus starting sanity at Levels 2 and 3 makes early-shift survivability safer
Cons
- ✗ No defensive starter item — no Taser, no Coffee, no Cola in the kit
- ✗ Per-heal recovery scales slowly — bad in short panic-heavy shifts with few cures
- ✗ Visual overlap with Dr. Harlow can confuse teammates who don't read nameplates

How to Play This Class
Treat patient throughput as the optimization target. Doctor's sanity income scales linearly with cured-patient count, so longer shifts and faster treatment loops directly inflate the class's value. Aim for 15-20 correct cures per shift; that nets 15-20 sanity, which is usually enough to offset the ambient passive drain and Mass-of-Eyes uptime entirely.
Accuracy matters more than speed. The class only procs on correct treatments — wrong treatments deal the standard wrong-treatment penalty AND give you zero sanity back. A 90% accuracy rate at moderate speed beats a 70% accuracy rate at maximum speed for Doctor specifically.
Level up priority: Push to Level 2 as soon as Animal Coin income permits. The starting sanity bonus stacks with the per-cure tick to give you a comfortable buffer through the first emergency event. Level 3 adds another bonus on top — worth the upgrade if you regularly run high-difficulty shifts.
For anomaly handling, Doctor has no offensive starter weapon. Coordinate with Security or Secret Agent classes for combat encounters (Skinwalker, Mimic Patient). On solo shifts against Skinwalker-heavy nights, upgrade to Level 3 first for the sanity buffer, or pick up a Taser from the office display case at Shift 3+ to cover the gap.
Team role: Doctor is the sustain anchor. In coordinated lobbies, pair with a Secretary (intake income) and a Security (combat coverage) — Doctor handles the treatment loop while the other classes feed patients and clear hostile encounters. Best solo configuration is medical-wing rotation where you can rack up heals without competing with teammates for patient access.
Patch History
Class System rework on 2026-06-19 (Class Update Part 1) added the three-tier upgrade structure that gives Doctor its current Level 2 / Level 3 starting sanity bonuses. The 2026-06-26 skin patch (Part 2) did not add a Doctor-specific skin — Doctor is not currently in the documented six-class skin roster.

Frequently Asked Questions
- Mid-tier difficulty. The per-heal sanity recovery is forgiving once you can diagnose accurately, but the class punishes misdiagnoses (no recovery + standard penalty). Start with Intern until your accuracy rate is reliable.
- Doctor costs 900 Animal Coins. Starter Intern shifts earn around 60-100 coins per completed run, so expect 10-15 shifts to unlock.
- Doctor heals reliably from Level 1 for 900 coins. Surgeon adds a speed boost on heal but costs 2,500 coins. Doctor is better value early-game; Surgeon is endgame once the unlock is affordable.
- Not as of the 2026-06-26 update. Skins are currently available for six classes: Intern, Nurse, Psychologist, Security, Head Nurse, and Secret Agent.
- No — class selection happens in the lobby before joining a shift. You'd have to leave and rejoin to change.
- Doctor has no offensive starter weapon. Coordinate with armed teammates (Security, Secret Agent), or pick up a Taser from the office display case at Shift 3+ to cover the combat gap.
- Doctor doesn't raise the absolute sanity cap — sustained healing keeps you closer to the starting cap longer. For raw sanity ceiling, Intern Level 3 (81%) is higher than Doctor's baseline.
- Deliberate visual echo in the design — Doctor's appearance is modelled on Dr. Harlow, the hospital's supervising NPC. They're distinct entities, but the visual link is intentional.

The accuracy class
Doctor's perk is sanity restored per correct treatment. The structure is similar to Secretary's per-check-in sanity, but the trigger is different — Doctor's procs fire on the treatment floor, not at the front desk.
The 900-coin unlock is a notable jump from Nurse (20) and Secretary (120). The pricing reflects that Doctor is a mid-game class, not an early-game unlock.
What "correct treatment" means in practice
The proc requires applying the right item to the right condition. Wrong-treatment applications fail (item doesn't proc, condition stays unresolved) AND eat the usual wrong-treatment penalty. So Doctor punishes misdiagnosis twice — once with the failed cure, once with the missing sanity income.
This makes Doctor a class for players who already trust their diagnostic flow. If you're still confusing similar symptoms (Bleeding vs Bruises, Flu vs respiratory cues), the Doctor passive doesn't fire often enough to justify the 900-coin spend.
How Doctor compares to Surgeon
Surgeon (2500 coins) does what Doctor does plus a movement-speed buff on each correct cure. The Surgeon proc compounds — multiple cures in succession stack into a transit-speed bonus that helps you reach the next treatment faster, which then procs again.
Doctor is the prerequisite skill-test for Surgeon. If you can run Doctor cleanly, Surgeon's price tag is justified. If Doctor's sanity income feels marginal, Surgeon will too.
Diagnosis-first habit
Speeds up Doctor's effective income: open the patient symptom panel first, get the diagnosis, then fetch the matching item. Most Doctor-class income loss comes from "fetch the closest item, hope it's right" attempts that fail and cost the proc.
