Eurydice, the engineering officer who turns shield damage into firepower
Eurydice is an epic engineering officer in Star Trek Fleet Command, and her kit is built around one idea: take a hit, hit back harder. Her captain ability rewards a ship for absorbing shield damage, and her officer ability tops those shields back up while the fight continues.
She belongs to the Mudd’s Company officer group, a crew of rogues and traders who back each other up through synergy bonuses. If you are building around that group, or you just want a survivability-leaning Technik officer for hostile grinding, Eurydice is worth a look.
This guide covers who she is, what her abilities do, where she fits, and how to crew her.
Who Eurydice is
Eurydice is an original character written for Star Trek Fleet Befehl rather than a face pulled from a Star Trek series or film. Her in-game story still gives her a clear personality. Abandoned by her parents and born into poverty, she learned to survive young, working as a pirate and scavenger before she found her real talent: connecting people.
She became a black market arbiter, matching sellers with buyers and specializing in ships and parts, earning a living on the small margin of each deal. The game describes her as someone who can read almost anyone’s body language and shift between manipulative and straight-talking depending on what a deal needs. She also supports a daughter, lives close to the financial edge, and wants a better life for her family.
Her officer group, Mudd’s Company, takes its name from Harcourt Fenton “Harry” Mudd, the con artist who appeared in the original Star Trek series and later in Discovery. Eurydice fits that group’s tone of working the angles rather than following the rulebook.
Eurydice’s role in STFC
Eurydice is a combat-support officer. As an engineering-class officer, her value shows up in sustained fights rather than mining or station defense. Both of her abilities trigger off shield damage, so she is at her best on a ship that expects to trade blows.
One limit matters before you build around her. Both her captain ability and her officer ability work against hostiles of level 70 and under. That makes her an early-game and mid-game pick for grinding hostiles in that range, not a tool for high-level targets. Plan her into crews accordingly.
Eurydice’s abilities
Captain ability: Opportunist
When Eurydice captains a ship and that ship loses shield health from a weapon attack, she increases the ship’s weapon damage by 10% (as of the latest Daten). The bonus is cumulative, so it can build over a fight as long as the ship keeps taking shield damage. One detail to know: weapons that fire multiple shots only trigger the bonus once per attack, and the ability applies against hostiles of level 70 and under.
On its own, a 10% starting bump is modest for an epic officer. Opportunist earns its place through the cumulative stacking and through synergy, which is covered below. Treat it as a payoff for a ship meant to soak shield damage, not as a burst-damage opener.
Officer ability: Delta Quadrant Technology
When the ship’s shields are depleted, Eurydice has a chance to heal shield health by 5%. The heal amount stays the same as she ranks up; what improves is the chance it fires. Like her captain ability, this works against hostiles of level 70 and under.
The chance to heal climbs with each promotion. The progression below is current as of the latest game data.
| Rang | Chance to heal shields |
|---|---|
| 1 | 35% |
| 2 | 45% |
| 3 | 55% |
| 4 | 65% |
| 5 | 75% |
Paired with her captain ability, the two work as a loop. Opportunist wants the ship to keep losing shield health; Delta Quadrant Technology helps put some of that shield health back, so the fight, and the damage bonus, can continue.
Where Eurydice shines
Eurydice fits a few specific spots.
She suits early-game and mid-game hostile grinding against targets level 70 and under. A ship that expects return fire can lean on her shield regeneration to stay in the fight longer while Opportunist builds up.
She also rewards a shield-tank playstyle. If your ship is set up to absorb damage on its shields rather than dodge it, both of her abilities stay active and feed each other.
She is a natural pick when you are building around Mudd's Unternehmen. Her synergy bonuses and synergy partners all sit inside that group, so she slots in cleanly next to the other rogue Offiziere.
How to get Eurydice
Eurydice is an epic officer tied to the Mudd’s Company group, so she shows up through the events and store rotations that feature those officers. Shard availability moves around as STFC cycles its content, so check the current event schedule and store offers rather than counting on a fixed source.
Ranking her up takes 1,425 shards in total across five ranks. The shard cost per rank climbs steeply at the top end, and her abilities reach full strength at rank 5.
| Rang | Shards to promote |
|---|---|
| 1 | 95 |
| 2 | 95 |
| 3 | 190 |
| 4 | 285 |
| 5 | 760 |
That last rank is most of the cost, and it is also where her officer ability hits its 75% heal chance. Decide whether the full rank-up is worth it based on how much you plan to use her, since most of the shards go into that final promotion.
Crewing Eurydice and her synergies
Eurydice carries class synergy bonuses, which means she contributes more when she sits next to officers of certain classes. As of the latest data, her synergy bonus is 5% with command-class officers, 2% with engineering-class officers, and 5% with science-class officers. In practice, a bridge built mostly from command and Wissenschaft officers gets the most out of her.
Her named synergy officers all come from Mudd’s Company. When Eurydice is crewed with them, she gains an extra bonus. The current synergy partners are Harcourt Fenton Mudd, Sesha, Ro Mudd, Goon, and Tiza at 5% each, and Ahvix at 2%. Both officer versions of Harcourt Fenton Mudd count toward this synergy.
Synergy is what lifts Opportunist above its base value. Stacking Eurydice with Mudd’s Company officers pushes the cumulative damage bonus higher and makes her captain ability meaningfully stronger. If you run her as captain, build the rest of the bridge from her synergy partners where you can.
Her character traits round her out. Eurydice’s traits are Deceptive, Charismatic, and Trader, a set that fits her black market background. Traits unlock in sequence, with each one opening up after the previous is complete.
Frequently asked questions
Is Eurydice good in STFC?
Eurydice is a solid situational pick rather than a must-have. She is strongest on a combat ship grinding hostiles level 70 and under, especially one crewed with her Mudd’s Company synergy partners. Outside that range and that crew, her impact drops, so judge her against what you actually need.
What does Eurydice’s captain ability do?
Her captain ability, Opportunist, increases the ship’s weapon damage when the ship loses shield health from a weapon attack. The bonus is cumulative and builds over a fight, though it only applies against hostiles of level 70 and under.
Where do you get Eurydice shards?
Eurydice shards come through the events and store rotations that feature Mudd’s Company officers. Because STFC changes its offers often, check the current event schedule and store rather than relying on a single fixed source.
Is Eurydice worth ranking up?
Her officer ability improves only in its chance to fire, climbing from a 35% heal chance at rank 1 to 75% at rank 5. Most of her 1,425-shard cost sits in that final rank. If you plan to use her regularly on hostile crews, the rank-up pays off; if she is a bench officer, the early ranks may be enough.
What ship is Eurydice best on?
She fits a combat ship that expects to take shield damage and stay in the fight, since both of her abilities trigger off shield hits. A ship you use to grind hostiles in her level range is the natural home for her.
Is Eurydice right for your crew?
Eurydice rewards a specific plan: a combat ship that soaks shield damage, a crew drawn from Mudd’s Company, and targets in her level 70 and under range. Bring those together and she is a capable survivability officer. If your roster is pointed at higher-level content, or you have no Mudd’s Company crew to pair her with, your shards will likely do more elsewhere.
