Who Doctor T’Ana is in STFC
Doctor T’Ana is a Federation Science officer in the Lower Decks Crew group, and she shows up on STFC players’ radar for one specific reason: her officer ability can drop a random debuff onto an enemy ship every round of combat. She does not carry a captain’s maneuver. Her job is to ride a bridge slot, not the captain’s chair.
That single quirk shapes how you crew her. If you got T’Ana from an event and you’re trying to figure out where she fits, this guide covers what her ability actually does, why her captain seat is dead weight, and which crews use her well.
She is epic rarity (four stars), maxes out at rank five, and takes 1,500 total shards to fully promote.
Star Trek background
T’Ana is the chief medical officer of the USS Cerritos, the California-class support ship at the center of Star Trek: Lower Decks. She holds the rank of Commander, she’s Caitian (a feline humanoid species), and she has been on the Cerritos since “Second Contact” in 2380. Gillian Vigman voices her on the show.
If you have only watched the marquee Trek series, the Cerritos is the support-ship premise that does the unglamorous follow-up work after the hero ships leave. T’Ana fits that tone. She is foul-mouthed, sharp with ensigns, and in canon she once told the senior staff she was a doctor, not whatever the situation in front of her happened to be. She also has a long-running romance with Cerritos security chief Shaxs and quietly mentored Ensign Tendi out of medical and into senior science officer training.
When you see her in the in-game Lower Decks Crew category, that’s a nod to the show, not her rank. She is a senior officer on the Cerritos, not a lower decker herself.
Role in STFC
T’Ana is a combat officer who lives or dies on her officer ability. STFC officers usually have two jobs that matter: a captain’s maneuver that buffs the whole ship, and a bridge officer ability that activates when she is in one of the two bridge slots.
T’Ana has none of the first kind. The captain seat with her in it gives no bonus at all. Players who don’t know that sometimes plug her into the captain chair and wonder why their hits feel weak.
What she does have is a bridge ability called Make a Mess. At the start of each round of combat, there is a chance she applies a random State to the enemy ship for three rounds. The State rotates between Morale, Burning, and Hull Breach. Morale strips the opponent’s mitigation. Burning ticks damage onto their hull. Hull Breach reduces hull repair and amplifies damage taken. Any one of those is a meaningful swing in PvP and against tankier hostiles.
The chance to trigger scales with her rank. At rank one it is 40 percent. At rank five it is 100 percent every round, as of the latest game data.
Captain ability: Chief Medical Officer
The captain ability listed on her in-game card is called Chief Medical Officer. The actual effect text reads, “This Officer does not have a Captain’s Maneuver.” Equipping her as the captain of a ship provides no benefit. Treat that as a hard constraint when you build a crew around her. She belongs in one of the two bridge officer slots, never in the captain seat. Whoever you put in the captain seat needs to come from a different officer.
Officer ability: Make a Mess
Make a Mess is the only reason she goes on a crew. On round start, T’Ana has a chance to apply a random State (Morale, Burning, or Hull Breach) to the enemy ship for three rounds. The State that gets applied is rolled each time the ability fires, so you do not get to pick which one shows up. The proc rate is below:
Current as of the latest game data.
| Rank | Make a Mess chance |
|---|---|
| 1 | 40% |
| 2 | 45% |
| 3 | 55% |
| 4 | 75% |
| 5 | 100% |
Practically, this means T’Ana is a different officer at rank five than she is at rank one. Below rank five, you are gambling on the proc. At rank five, the proc is automatic at the top of every combat round.
Where she shines
A few situations she fits well, all of them assuming she has been promoted high enough that the proc rate is reliable.
She works on hostile-grinding crews that want extra damage uptime. Burning and Hull Breach both chip away at hostile hull, and Morale removes the mitigation buff that hostile crews lean on. Pair her with a strong damage captain you already have promoted and let the random States do extra work in the background.
She fits PvP crews that want to disrupt the enemy more than out-tank them. Stacking a random State every round can swing a close fight, especially against opponents who built around defense, mitigation, or hull tanking. The catch is that the chance is below 100 percent until rank five, so the swing is most reliable on a fully promoted T’Ana.
She has a role on captain-passive crews. Because she contributes nothing as captain, the spot is usually filled by an officer whose own captain’s maneuver is the strongest one available to you. T’Ana then sits in a bridge slot and quietly piles up Burning ticks without changing the captain bonus.
How to get Doctor T’Ana shards
T’Ana usually shows up through event-related rewards, recruit token pulls, and faction store rotations tied to Lower Decks content. Exact availability shifts month to month, so check the current event and store screens in-game before assuming a fixed path to shards. The total cost from recruitment through full promotion is 1,500 shards, broken down per rank below.
| Rank | Shards to promote | Cumulative total |
|---|---|---|
| 1 | 100 | 100 |
| 2 | 100 | 200 |
| 3 | 200 | 400 |
| 4 | 300 | 700 |
| 5 | 800 | 1,500 |
Synergies and crew building
T’Ana sits in the Lower Decks Crew synergy group. Other officers in that group share class-synergy bonuses when they are crewed together. The exact Command, Engineering, and Science percentages were not pulled into this article, so check the in-game synergy screen for current numbers. Beyond the group itself, her best crewmates depend on what you are trying to do:
For PvP and hostile grinding, pair her with a captain whose ability scales the damage your ship is already doing. The States T’Ana applies amplify that damage either by stripping mitigation (Morale) or by adding ticks (Burning).
For tankier fights, slot her with a captain whose maneuver covers your survivability and let her own ability handle the chip damage.
Across both cases, the second bridge slot is the one you want to think hardest about. T’Ana plus one other strong bridge officer plus a real captain is the usual shape.
Frequently asked questions
Is Doctor T’Ana worth ranking up?
If you are using her in PvP or hostile grinding, yes. Make a Mess is much weaker below rank five because the proc rate is under 100 percent. At rank five it fires every round, which is when she earns the shards you spent on her. Earlier in the game, her shards can sit in inventory while you prioritize officers with captain abilities.
Why does she do nothing as captain?
By design. The in-game text on her captain seat is the literal line “This Officer does not have a Captain’s Maneuver.” Whoever you put in the captain seat needs to come from a different officer.
What ship is she best on?
Any ship that benefits from extra State damage or removed mitigation. That covers most combat ships from interceptors through battleships. She is not picky about hull class.
How many shards to max her out?
1,500 shards total from recruitment through rank five. The per-rank breakdown is in the shard table above.
Where do her shards come from?
Event rewards, recruit token pulls, and faction store rotations tied to Lower Decks content. Availability changes regularly, so check the current event and store screens in-game rather than assuming a fixed source.
The short version
Doctor T’Ana is a niche fit but a useful one. Players who already have strong captains are her main audience, since she pairs cleanly with anyone who can carry the captain slot while she leans on Make a Mess. If you are starting out and short on good captains, spend your event currency elsewhere first and come back to T’Ana when you can sit her behind a captain whose bonus actually moves the fight.
