Classes are persistent role choices bought with Shards or, for at least one currently documented option, Robux. The useful question is not which class has the longest perk list. It is which class helps with the part of a shift that repeatedly ends your run: movement, diagnosis, treatment, sanity pressure, survival, or anomaly response.
Currently documented class roster
Rookie
Reported cost: 250 Shards.
The entry purchase. Use it to learn how the class menu and upgrades behave before committing a larger balance.
Cost corroboratedWard Assistant
Reported cost: 400 Shards.
Community descriptions associate it with carrying supplies. Confirm the live perk text before buying.
Single-source reportReceptionist
Reported cost: 750 Shards.
Community coverage connects it with patient-flow support. It fits organized groups more naturally than a blind solo purchase.
Cost corroboratedSurgeon
Reported cost: 1,000 Shards.
A treatment-oriented choice in current guides. Check whether the live wording matches the task that slows your runs.
Cost corroboratedSurvivor
Reported cost: 1,500 Shards.
Reported as a resilience-oriented class. It may forgive pressure, but it cannot replace correct patient decisions.
Cost corroboratedChief Doctor
Reported cost: 2,500 Shards.
A higher-cost general medical role in one current class guide. Treat its exact benefits as unverified.
Single-source reportTherapist
Reported cost: 3,000 Shards.
Community reporting links it to sanity support. Verify whether the effect helps self, team, or both in the current menu.
Single-source reportExorcist
Reported cost: 4,000 Shards.
An anomaly-response specialist in current descriptions. High price makes live-menu verification especially important.
Cost corroboratedPlague Doctor
Reported cost: 6,000 Shards or 360 Robux.
The largest documented Shard commitment. Do not infer best-in-slot status from cost alone.
Cost corroboratedOpen the complete class list for source-by-source notes. Prices can change during beta, so the menu shown in your current server is final.
Choose by repeated failure
Review the last two failed shifts. If unfinished treatment caused both, inspect a treatment-oriented class. If sanity pressure repeatedly destroyed your evidence checks, inspect sanity or survival support. If the team loses time moving supplies or patients, inspect support roles. If confirmed anomalies are the point of collapse, compare an anomaly-response role only after the group already diagnoses reliably.
This method avoids buying a prestigious class that solves a problem you do not have. It also separates a route mistake from a stat problem. A class cannot fix calling the next patient early, misreading the active objective, or continuing ordinary treatment after a reveal.
Spend Shards in checkpoints
Treat 250, 750, 1,500, 3,000, and 6,000 as planning checkpoints derived from reported prices, not a mandatory ladder. Redeem current code candidates before making a purchase, then compare the live balance with the exact menu price. Keep a reserve if an update has just changed the title or added a night, because class balance can move with the content.
The safest first purchase is one whose text you understand and whose benefit applies frequently. The safest expensive purchase is one you have observed a teammate use in the same game build. Avoid converting Robux only because the Shard path looks slow; Robux spending is irreversible, while reported costs can be outdated.
Solo and squad roles
Solo players need broad value. Prioritize a benefit that applies to most patients or protects the resource that ends your runs. Squad players can specialize, but should avoid four people assuming someone else owns the patient decision. Assign one case lead, one treatment operator, and support as the live objective allows.
Class names do not grant authority over the task. The person reading the objective should call the next step, and anyone seeing contradictory evidence should pause the branch. A specialist should make the protocol clearer, not create parallel clicking.
Progression and upgrades
Current community coverage describes class levels and upgrades, but the checked sources did not provide enough stable, creator-owned detail to publish exact level tables. Use the live class panel for upgrade price, cap, and effect. Record before-and-after values if you are testing; one successful run is not enough to prove a hidden percentage.
The progression guide gives a budget route, while class selection turns common failure patterns into purchase questions. Both deliberately defer to current menu wording.
Class mistakes to avoid
Do not call a class official meta because one guide ranks it highly. Do not copy exact percentage claims from an old patch. Do not assume the most expensive role has the best solo value. Do not purchase around a bug before trying the troubleshooting guide. Finally, do not spend Robux through any external site or person; only use Roblox’s in-experience purchase flow.
Classes FAQ
How many classes are documented?
Nine appear in the current detailed class source. Six names and costs are independently corroborated; three remain single-source reports.
What is the best first class?
There is no evidence-backed universal best. Choose the lowest-cost live option that addresses a repeated failure and whose menu text is clear.
Are the prices official?
No. They are current community reports checked on 2026-08-06. The live class menu is authoritative.
Can a class identify anomalies automatically?
No such universal mechanic is claimed here. Continue to use the detection protocol.
Should I buy Plague Doctor with Robux?
Only after verifying the live price and effect yourself. Its reported cost does not prove it is necessary or optimal.
