Who is Mirek in STFC?
Mirek is a Rare Romulan science officer whose officer ability hits Federation ships harder the more you promote her. She is part of the Romulan Patriots synergy group, with class bonuses for Command and Engineering seats and a smaller bonus for Science. If you fight Federation hostiles often, or you are building a crew that punishes the blue side of the map, she is one of the cheaper Rare officers worth looking at.
The shorthand: a low-rarity officer with a damage multiplier against Federation targets that scales to a very large bonus at higher ranks. Her captain seat is more situational, and the rest of this guide walks through where she fits and where she does not.
Star Trek background
Mirek does not appear in canon Star Trek. She was created for Star Trek Fleet Command as the younger sister of Liviana Charvanek, the Romulan Commander from the original series episode “The Enterprise Incident.” In that story, the Commander tries to obtain a Federation cloaking device by recruiting Spock, who turns out to be running an undercover operation against her. Charvanek is canon; Mirek is the game’s invention sitting alongside her.
Her in-game bio gives her a science specialty in deflection fields and radiation phenomena. She also gets paired with her sister inside the Romulan Patriots group, a small handful of officers loyal to the Romulan Star Empire. None of this affects how she plays, but it explains why the game places her next to other Patriots officers in your roster screen.
Mirek’s role in STFC
Mirek is a damage amplifier tuned specifically against Federation targets. She is not a generalist. If the opponent or hostile in front of you is not flying a Federation ship, her officer ability does nothing for the fight. That makes her a slot-in piece for known matchups rather than a default seat in an all-purpose PvE crew.
Her captain ability sits in a different niche: a chance to apply Burning to the attacker when your ship gets hit. Burning is a damage-over-time effect, so the captain seat rewards ships that expect to take incoming fire and live long enough for the burn to add up. Glass cannons will not benefit much; tankier ships and hostile-grinding builds will.
Most players treat Mirek as an officer ability piece first and a captain second. Her real value is on the bridge of a Federation-hunting crew, with someone else in the captain seat who multiplies Defense or damage.
Captain ability: Burning Vengeance
As captain, Mirek’s ship has a 20% chance to apply Burning to the attacker for 1 round each time it gets hit by a weapon attack. Weapons that fire multiple shots per round only roll the chance once per attack rather than per shot, so high rate-of-fire opponents do not multiply your trigger count.
This reads as a defensive captain ability dressed up as retaliation. You want to be tanky so the trigger fires often, and you want the Burn to stack across multiple rounds against tougher enemies. The 20% figure is as of the latest data, and the underlying source data for this ability does not give a clean rank-by-rank progression we can verify, so treat the rank-1 chance as the headline and assume the bonus scales modestly with promotion rather than copying any tables you might see elsewhere.
Practical use cases for Mirek-as-captain: long fights where you trade hits over many rounds, like low-effort hostile grinding or station defense. Avoid burst PvP or fast PvE clears, where the Burn ticks rarely matter before the fight ends.
Officer ability: Acid Bitterness
On the bridge as an officer, Mirek increases the ship’s Damage against Federation ships by a percentage of the crew’s total Defense stat. The percentage climbs sharply with each promotion. The ability does nothing against non-Federation ships, which is why this is a situational pick rather than a default damage seat.
Current per-rank scaling, as of the latest game data:
| Rank | Damage vs Federation |
|---|---|
| 1 | 25% |
| 2 | 35% |
| 3 | 75% |
| 4 | 175% |
| 5 | 500% |
The jump from rank 4 to rank 5 is large enough that fully ranking her changes the math on any crew that includes her. Below rank 5, she is a respectable supporting piece against Federation targets. At rank 5, she becomes a meaningful damage multiplier, assuming the rest of the crew brings Defense to scale off of.
Because the bonus reads off the crew’s total Defense, this ability rewards stacking Defense-buffing officers on the same bridge or running ships with high base Defense. The interaction with damage-modifier officers can compound in your favor, but only when the target flies a Federation flag.
One implication worth flagging: if you are deciding between leveling Mirek and ranking her, the rank threshold matters more here than for many officers. Levels mostly raise base stats; rank changes the percentage on her officer ability, and the percentage is the whole point.
Where Mirek shines
The clearest fit is anywhere Federation hostiles or armadas are the target. Federation faction grinding is the most common reason to slot her in, and mission lines or events built around Starfleet enemies push her value higher. She also has a place in PvP if you are hunting a known Federation player and want to skew the matchup.
She does less for you when the target is Klingon or Romulan, both of which come up often in PvE rotations. Keep her on a swap crew rather than your daily driver if you alternate factions through the week.
For new players still climbing through faction space, Mirek can pull above her weight if your current grinding lane is Federation. Rare officers are cheaper to push to rank 5 than Epics, and the rank 5 jump on her officer ability gives a small account a damage tool it would otherwise be missing.
How to recruit and rank up Mirek
Mirek is recruited through shards, and her rarity puts her in the Rare pool rather than the Epic pool. The specific sources for her shards rotate with events and store offerings, so check current Faction Store inventories and the latest recruit token sources in the recruit screen for what is live this week.
Her promotion costs grow steeply at higher ranks, with the rank 5 promotion costing several hundred shards on top of what you already spent to get there. Plan the rank-5 push around an event where her shards are reliably available, not as an impulse spend.
Leveling is the cheaper half of the work; ranking is the expensive half. If your shard supply is thin, level her up to the next rank’s cap and pause until the next event drops more of her into the game.
Crew synergies and pairings
Mirek belongs to the Romulan Patriots synergy group with her sister Liviana Charvanek. As a Science-class officer in the captain seat, she gets a 10% synergy bonus from a Command-class bridge officer and another 10% from an Engineering-class bridge officer, with a smaller 5% bonus for Science-class. The practical takeaway: when she captains, the other two bridge seats are usually better filled with non-Science officers to max her synergy contribution.
When she rides as an officer rather than captain, the goal is to pair her with anyone who multiplies Defense, since Acid Bitterness reads off the crew’s total Defense. Captains that bring straight Defense buffs in their captain ability are the obvious shortlist, and bridge officers that contribute Defense help too.
She is rarely the right pick for a PvE crew that fights Klingon space, since her officer ability does not trigger there. Treat her as a Federation-tagged tool you slot in when the target asks for it.
Frequently asked questions
Is Mirek any good?
She is good in her lane and unremarkable outside it. Against Federation ships, especially at rank 5, she is a strong damage amplifier for a Rare officer. Against any other faction, she does nothing on the bridge.
Where do you get Mirek shards?
Look for her in event stores and rotating recruit token chests. The exact source set shifts with each event cycle, so check what is live in the recruit screen and Faction Store rather than relying on older guides.
What ship is Mirek best on?
Any ship you plan to fight Federation targets with, especially ones that can stack Defense from crew and research. As captain, ships that survive long enough to apply multiple Burns benefit most.
Is Mirek worth ranking to 5?
If you regularly farm Federation hostiles or run Federation-themed events, yes. The rank 5 jump in her officer ability is large enough to change the value of every crew she sits on. If you rarely fight Federation, the shard spend is better saved for a more general-use officer.
Does Mirek pair with her sister Liviana?
They share the Romulan Patriots synergy group, which is more a flavor pairing than a hard mechanical synergy in current builds. They can sit on the same bridge without conflict, but the real stacking comes from the captain plus officer ability combo on whichever ship you put them on, not from any group bonus.
Bottom line for new recruits
Mirek is a specialist. If you fight Federation often or want a cheaper Rare option for anti-Fed content, pull her shards when the opportunity comes up and push her to rank 5 over time. If your normal targets are anywhere else, she is a swap-crew piece rather than a daily driver, and your rank-up budget is better aimed at a generalist first.
