Who is Six of Eleven in STFC?
Six of Eleven is the Borg-assimilated form of the Klingon warrior Kras and one of the Epic Command officers in the Unimatrix Twelve sub-collective. His bridge seat boosts Armada damage by converting your crew’s Attack stat into extra penetration, and his captain ability chips through enemy shields by reading off your crew’s Defense stat.
Players bring him in for two reasons. The first is Armadas: at max rank, his bridge ability turns nearly half of your crew’s Attack into Accuracy, Armor Piercing, and Shield Piercing on every hit against an Armada Target. The second is shield stripping, where his captain ability shaves a chunk off the opponent’s Shield Health on each weapon hit, scaled by the combined Defense stat your crew brings to the ship.
This guide covers what each ability does, where he fits in a crew, his shard and Officer XP costs, and how the Unimatrix Twelve synergy ring shakes out around him.
Star Trek background
In canon, Kras is the Klingon warrior introduced in the original-series episode “Friday’s Child” (1967). Played by Tige Andrews, he was sent to Capella IV in 2267 to win mining rights to topaline for the Klingon Empire, and he attached himself to Maab’s faction during a power struggle against the Teer Akaar. The character is descended from the Klingons changed by the Klingon augment virus the geneticist Antaak introduced in 2154, which is why he looks more human than ridged.
His on-screen run ends in the same episode. After the standoff with Captain Kirk’s landing party, Kras pulls a stolen Starfleet phaser, and Maab’s lieutenant Keel kills him with a thrown kleegat. The name “Kras” appears only in the credits; every line of dialogue in the episode just calls him “the Klingon.”
STFC takes that character and reroutes him into the Borg storyline. The in-game flavor text has Kras overseeing a routine Klingon mining expedition when an assimilation fleet rolls over him; the warrior who once advised the Empire ends up speaking on behalf of the Collective. That is why Six of Eleven sits in the Unimatrix Twelve roster alongside the other assimilated officers, even though the rest of the sub-collective are mostly Starfleet cadets rather than Klingons.
Six of Eleven’s role in STFC
Six of Eleven is an Epic rarity Command officer in the Borg roster, grouped under Unimatrix Twelve, with a Neutral faction. He is built for Armada work first, with a captain seat that can put in real shield-stripping work on combat ships. He is not a healer, an economy officer, or a hostile farmer. He is a damage multiplier whose payoff depends on the rest of your crew’s stat lines.
That puts him in two clear lanes: a bridge seat on Armada-focused crews where the Armada-only condition is fine, and the captain seat on combat ships that want a steady source of opponent shield damage on top of their existing kit.
Captain ability: We are the Borg
When Six of Eleven sits in the captain’s chair, every weapon hit your ship lands subtracts a percentage of your crew’s combined Defense stat from the opponent’s Shield Health. The rank-1 value, current as of the latest data, is 20% of total crew Defense per hit. Weapons that fire multiple shots only trigger this once per attack rather than once per shot.
Two things to keep in mind. First, this ability does not present clean per-rank scaling in the live data, so the rank-1 number is the only one worth quoting; the bonus may shift with promotions in ways that aren’t worth guessing at without confirmation in-game. Second, the bigger the Defense stat on the rest of your crew, the more shield damage each hit deals, so pairing him as captain with high-Defense officers in the other two seats stretches the ability further than rank-up alone.
Officer ability: Defenses are irrelevant
On the bridge, Six of Eleven converts a slice of your crew’s Attack stat into raw penetration when you fight Armada Targets. Each weapon hit adds a percentage of total crew Attack to your ship’s Accuracy, Armor Piercing, and Shield Piercing. The bonus only fires against Armada Targets; it does nothing in PvP, hostile grinds, or station strikes.
Current as of the latest data:
| Rank | Bonus to penetration from crew Attack |
|---|---|
| Ensign I | 5% |
| Lieutenant JG II | 10% |
| Lieutenant III | 20% |
| Lt. Commander IV | 30% |
| Commander V | 40% |
The jump from Lieutenant III to Commander V is where the rank-up earns its cost. The per-hit bonus doubles between those two ranks, and at Commander V you are converting 40% of your roster’s Attack into three separate penetration stats on every Armada hit. Like the captain ability, multi-shot weapons trigger this once per attack, not once per shot.
Where Six of Eleven shines
Three situations make him worth the seat.
The first is Solo and Formation Armadas. His bridge ability was designed for Armada Targets, so any ship you take into an Armada is a candidate for a Six of Eleven bridge seat. He stacks with other Armada-flavored officers and benefits directly from a crew built around raw Attack values.
The second is Unimatrix Twelve crews. The Borg cadet roster shares named synergies with him, and at Command class he picks up the same big synergy multipliers most of his sub-collective gets when grouped together. Pairing him with two more Unimatrix Twelve officers gives you a crew that snaps into shape with very little fuss.
The third is using him as captain on combat ships that have room for high-Defense officers in the other seats. Because the captain ability reads off your crew’s combined Defense, putting beefy tank officers next to him stretches the shield-strip per hit further than promoting him alone would.
How to get Six of Eleven shards
Six of Eleven is a Borg-track Epic officer, so his shards turn up alongside the rest of the Unimatrix Twelve set: Borg-themed events, recruit drops, and the Borg recruitment store when it cycles in. The store and event lineup rotate often, so check the current rotation rather than assuming any one source is live this week.
Promotion shard costs:
| Rank | Shards to promote | Cumulative shards |
|---|---|---|
| Ensign I | 115 | 115 |
| Lieutenant JG II | 115 | 230 |
| Lieutenant III | 230 | 460 |
| Lt. Commander IV | 345 | 805 |
| Commander V | 920 | 1,725 |
Beyond shards, ranking him past Lieutenant JG II eats Independent Credits, Officer XP, and Command Badges on the usual Borg-officer schedule. The Command Badge wall is the most common bottleneck for accounts that aren’t deep into Borg progression yet.
Character traits
Six of Eleven has three traits that unlock in order. Assimilated comes first and is cheap to finish. Ruthless opens after Assimilated wraps, with a noticeable cost dip at Level 2 before the price climbs again. Relentless is the long haul: nine levels deep, with the back half of the tree pulling more Officer XP than the first six levels combined.
| Trait | Per-level Officer XP |
|---|---|
| Assimilated (3 levels) | 1,500 / 2,700 / 3,800 |
| Ruthless (4 levels) | 7,650 / 6,000 / 7,000 / 8,850 |
| Relentless (9 levels) | 10,000 / 4,000 / 7,000 / 10,000 / 15,000 / 23,000 / 42,000 / 68,000 / 107,000 |
If you are stockpiling Officer XP, Relentless is the trait to plan around. Level 9 alone costs more than Assimilated, Ruthless, and the first six levels of Relentless put together.
Synergy officers and crew building
His class synergy bonuses, when he is captain, are Command 10%, Engineering 40%, and Science 40%. That pattern reads as a captain who pays out more when the other seats are Engineering or Science than another Command officer, which is unusual for a Command captain and worth working into your crew planning.
Named synergy officers (current as of the latest data):
| Officer | Synergy |
|---|---|
| One of Eleven | 10% |
| Two of Eleven | 40% |
| Three of Eleven | 10% |
| Four of Eleven | 40% |
| Five of Eleven | 40% |
| Seven of Eleven | 40% |
| Eight of Eleven | 40% |
| Nine of Eleven | 10% |
| Ten of Eleven | 40% |
| Eleven of Eleven | 40% |
| Hugh | 40% |
| Ghalenar | 40% |
| Borg Queen | 10% |
| Dezoc | 40% |
| Gossa | 40% |
Most of his Unimatrix Twelve crewmates land at 40%, which is the practical reason Borg crews glue together so cleanly. Any two of the 40% officers in the other seats keep the synergy multiplier high while you build whatever Armada or shield-strip crew you actually need. The 10% slots are useful to know about for crew swapping when you do not have the 40% options available, but they aren’t where the value sits.
Frequently asked questions
Is Six of Eleven worth the rank-up?
If you run Solo or Formation Armadas regularly, yes. The bridge bonus rises from 5% to 40% between Ensign I and Commander V, so the promotions translate directly into more penetration per hit on Armada Targets. Outside Armadas his bridge ability does nothing, so accounts that do not run Armadas should weigh the rank-up against other officers competing for the same Borg resources.
Where do you get Six of Eleven shards?
Borg recruitment drops, Borg-themed events, and store offers in current rotations. The lineup changes often, so check what is live before committing to a pull strategy.
What ship is Six of Eleven best on?
Whichever ship you take into Armadas. His bridge bonus is conditional on the target being an Armada Target, so the ship matters less than the activity. For the captain seat, any combat ship with two high-Defense officers in the other seats will get more out of the shield-strip than a stat-light crew.
Does his bridge ability work against hostiles or in PvP?
No. The bonus only triggers when the target is an Armada Target. He still occupies a bridge seat in those activities, which is the trade-off for the Armada upside.
Is his captain ability worth using over a dedicated combat captain?
It depends on what you already field. The shield strip is real, especially if your crew Defense is high, but it does not directly add to your Attack the way most combat captains do. Bring him as captain when you want shield pressure rather than burst damage.
If your account is mid-game and starting to push into Armadas or Borg progression, Six of Eleven earns his slot quickly once he is at Lieutenant III or higher. If you are not running Armadas and have other Borg officers competing for the same shards, save the Command Badges for an officer whose ability fires in more of your activities first.
