The basics
Masriad Vael is a 4-star epic officer in Star Trek Fleet Command and the head of the Symbiosis officer group. She is a joined Trill whose symbiont came from the Mirror Universe, which makes her one of the more unusual characters the game has added. In a crew she does her best work below decks, feeding extra critical chance to your ship after enemies open fire on you.
She can also sit on the bridge as the active officer for a more defensive setup. Her on-bridge ability bumps up Apex Barrier against Invading Entities, the true-damage shield you want stacked deep when you are taking sustained fire from armadas and similar PvE threats.
One important note up front: Masriad Vael does not have a captain maneuver. Putting her in the captain seat gives you no buff at all, so plan around using her below decks or as the bridge officer instead.
Who she is in Star Trek
Trill are a humanoid species from the Alpha Quadrant in Star Trek canon. A small fraction of the population hosts a sentient lifeform called a symbiont, and a joined Trill carries the memories and personality of every previous host the symbiont has lived through. The joining is irreversible. Once the binding is complete, the host and symbiont depend on each other to survive. Famous canon examples include Jadzia Dax and Ezri Dax from Deep Space Nine and Odan from The Next Generation episode “The Host.”
Masriad Vael is an original character created for Star Trek Fleet Command, but she draws on canon Trek in two ways. First, she is a joined Trill, so she carries the same multi-lifetime perspective as Jadzia and Ezri. Second, her symbiont came from the Mirror Universe, the parallel reality first explored in the original-series episode “Mirror, Mirror” and revisited in Deep Space Nine, Discovery, and Enterprise. Her version of the Vael symbiont fell through dimensions to the Prime Universe roughly three centuries ago, and Masriad is the latest in a long line of Prime Trill hosts for it.
In the game’s flavor text, she leads a small rogue crew of treasure hunters who pull off heists at the edges of the law. That tone shows up in her below-deck ability name, The Winning Gambit, and in her place at the head of the Symbiosis group.
Her role in STFC
Mechanically, Masriad Vael is a Command-class officer aimed at PvE combat. Her abilities give nothing on offense the way a pure damage officer would. Instead, she helps your ship survive a beating from Invading Entities and turns reactive damage from hostiles, armadas, or Invading Entities into a slowly building critical-chance bonus that pays off over a long fight.
If you spend a lot of time grinding Invading Entities, Borg-style armadas, or any fight that goes longer than two rounds, she is worth looking at. If your priority right now is solo-armada burst damage or PvP, she will not move the needle for you.
Abilities
Captain ability: Chain of Command
She does not have one. The card lists a captain ability called Chain of Command, but the in-game text is explicit: equipping Masriad Vael as the captain of a ship provides no benefit. Treat the captain seat as off-limits for her and put a real captain there instead.
Officer ability: Honor Among Thieves
When combat starts against an Invading Entity, Masriad Vael adds Apex Barrier to your ship. Apex Barrier is a true-damage mitigation pool that sits on top of your normal mitigation: every 100 points of Apex Barrier raises the amount of damage your ship can absorb by 1%. That makes her bridge ability a clean fit for any IE fight where survival is the bottleneck.
The published per-rank values are below. These are current as of the latest game data and may shift with patches.
| Rank | Apex Barrier added |
|---|---|
| 1 | 500 |
| 2 | 1000 |
| 3 | 1500 |
| 4 | 2750 |
| 5 | 5000 |
Below deck ability: The Winning Gambit
The Winning Gambit triggers when your ship is hit by an Armada, Invading Entity, or Hostile. After the hit lands, your critical chance goes up by a small amount for four rounds. The bonus stacks as the fight goes on, so the longer the combat, the more crit she has handed you by the back half of the engagement.
As of the latest game data, the published per-rank crit-chance values are 4%, 5%, 6%, 8%, and 12% for four rounds. The shape of the ability tells you how to use her. She does nothing for the first incoming shot. Her value piles up in extended fights, which lines up with the role of the Symbiosis crew as an armada and Invading Entity team.
Where she shines
Three situations make Masriad Vael feel worth the recruit and rank-up effort.
- Invading Entity grinds. Her bridge ability and her below-deck ability both trigger against IE targets, and Apex Barrier is exactly the stat you want when an IE is chewing through your hull.
- Armada and solo-armada fights that drag on. Her crit-chance buff scales with rounds spent under fire, so a slow armada works in her favor.
- The full Symbiosis crew. Paired with the other three Symbiosis officers, she stops being a single tool and turns into part of a coherent armada-and-IE setup with extra shots, mitigation reduction, crit chance, and crit damage all coming from the same crew.
How to get her
Masriad Vael was introduced in Update 71 as part of the Symbiosis Part 2 rollout. Her shards have rotated through several event tracks and the in-game stores since release. The mix changes patch to patch, so check the current event calendar and the recruiting and faction store rotations rather than relying on a single source. The total shard cost to recruit her and run her to her max rank is 1,500.
Synergies and crewmates
Masriad Vael sits in the Symbiosis officer group with three other named officers: Dajash Tolra, Toli, and Byr Ch’Kelrer. The standard Symbiosis configuration puts Byr Ch’Kelrer on the bridge for the critical-damage buff and Masriad Vael below decks for the critical-chance buff. Dajash Tolra brings extra armada loot when his synergy is filled out, and Toli covers the rest of the kit. The result is a crew built around extended PvE fights against armadas and Invading Entities.
A common addition is Tom Paris below decks for extra mitigation. The Symbiosis crew leans hard into offense and does not bring much of its own damage reduction, so a defensive officer in the spare below-deck slot rounds the setup out.
Shard cost to rank her up
The cost to push Masriad Vael from recruit through rank five, as of the latest game data:
| Rank | Shards to promote | Cumulative total |
|---|---|---|
| 1 | 100 | 100 |
| 2 | 100 | 200 |
| 3 | 200 | 400 |
| 4 | 300 | 700 |
| 5 | 800 | 1500 |
Frequently asked questions
Is Masriad Vael any good?
She is a strong fit if you spend serious time on Invading Entities or armadas and you can run her with the rest of the Symbiosis crew. If you mostly do mining, mission-running, or PvP, she is much lower priority.
Can I put Masriad Vael in the captain seat?
No. Her captain ability gives no benefit. Use her on the bridge as the active officer, or below decks for the crit-chance bonus.
Where do I get Masriad Vael shards?
Her shards rotate through event tracks and stores. The schedule changes between patches, so check the current event calendar and store inventories in your game client rather than assuming a fixed source.
What ship is Masriad Vael best on?
Any ship you take into long Invading Entity or armada fights. Her abilities care about the type of target and the length of the fight rather than any specific ship class, so put her on whatever you are actually using for PvE.
Bottom line
Masriad Vael is a focused PvE officer. She gives no captain buff and she will not move the needle in PvP or early-game faction grinds. What she does do, in a Symbiosis crew on a PvE bridge, is keep your ship alive in IE fights and turn long armadas into slow critical-strike pile-ons. If that matches how you actually spend your in-game time, she is worth chasing. If it doesn’t, save the shards.
