Who is Ten of Eleven in STFC?
Ten of Eleven is the Engineering officer in the Unimatrix Twelve sub-collective and an Epic-rarity miner pull. His bridge ability adds straight Mining Speed to whatever ship he sits on, and his captain ability stacks an extra Mining Speed bonus on Parsteel, Tritanium, and Dilithium nodes. Together they make him the cleanest Borg pick for accounts that spend a lot of time parked on mining nodes.
Players know him as the Borg drone studying Tribbles. The in-game flavor text leans into that gag: the Collective sees the Tribbles’ asexual reproduction rate as a potential weapon, and Ten of Eleven is the first attempt at weaponizing the species. The existing wiki page also notes he was originally listed as “Ten of Ten” before Eleven of Eleven shipped, which is a small piece of release-order trivia some players still ask about.
This guide covers his abilities, his rank-up costs, his Engineering-officer traits, and how the Unimatrix Twelve synergy ring fits around him on a mining crew.
Star Trek background
Ten of Eleven himself is an STFC-original character. The canon hook is the Tribble, the rodent-like species from the original-series episode “The Trouble with Tribbles” (1967), reused on Deep Space Nine in “Trials and Tribble-ations” and the Short Treks short “The Trouble with Edward.”
Tribbles are small, furry, non-intelligent creatures from Iota Geminorum IV. They coo when touched, which has a sedative effect on humans, and they reproduce at a famously absurd rate. Worf summed up the Klingon view in 2268: feed one more than a morsel of food, and in a few hours you have ten tribbles, then a hundred, then a thousand. The Klingon Empire treated them as an ecological menace and dispatched armed ships to eradicate them across Klingon space.
The Short Treks short adds the canon precedent the Borg flavor text plays on. Edward Larkin of the USS Cabot, working with sample tribbles in the mid-23rd century, spliced his own DNA into the species to speed up reproduction so they could be farmed as food. The modified tribbles overran the ship, then the nearby planet Pragine 63, then eventually made their way into Klingon territory. STFC takes that idea, swaps Larkin for the Collective, and casts Ten of Eleven as the drone running the experiment.
Ten of Eleven’s role in STFC
Ten of Eleven is an Epic-rarity Engineering officer in the Borg roster, Unimatrix Twelve group, with a Neutral faction tag. He is an economy officer, not a combat or hostile killer. His whole kit feeds Mining Speed: a bridge boost that always works on whatever you mine, and a captain ability that piles a second layer of bonus on the three station resources.
That puts him in two clear lanes. The bridge seat fits any mining ship you want to push faster on resource nodes. The captain seat suits a dedicated Parsteel, Tritanium, or Dilithium runner you take out for long hauls, because the captain stack only applies to those three resources and stays useful regardless of which one you happen to be farming that week.
Captain ability: Multiplicative Extraction
When Ten of Eleven sits in the captain’s chair, your ship mines Parsteel, Tritanium, and Dilithium faster. The rank-1 value, current as of the latest data, is +50% Mining Speed on those three resources. The ability does nothing for gas (Hydrocarbon, Methanogenic, Halogenic), crystal types beyond Dilithium, or any non-station resource.
The captain ability does not present clean per-rank scaling in the live data, so the rank-1 number is the only value worth quoting. Promoting him keeps unlocking trait levels and rank ceilings, but the captain bonus on Parsteel, Tritanium, and Dilithium should be treated as the rank-1 value until corroborating in-game footage of higher ranks shows otherwise.
Officer ability: Tribble Mining Collective
On the bridge, Ten of Eleven adds a flat Mining Speed bonus to the ship, no matter what the ship is mining. Resource type does not matter here: gas, crystal, ore, gas-only nodes, sticky resource events, the bridge bonus applies. That is what makes him a default bridge pickup for any mining ship in the fleet.
Current as of the latest data:
| Rank | Mining Speed bonus |
|---|---|
| Ensign I | 80% |
| Lieutenant JG II | 100% |
| Lieutenant III | 120% |
| Lt. Commander IV | 140% |
| Commander V | 160% |
The numbers scale cleanly across ranks, with a steady 20 percentage-point gain per promotion. The bonus stacks with crew members that have related mining buffs, with refinery upgrades, and with the captain ability on the resources Multiplicative Extraction covers, which is where stacking him as both captain and bridge officer pays off for Parsteel, Tritanium, and Dilithium runs.
Where Ten of Eleven shines
Three situations make him worth the seat.
The first is dedicated station-resource mining. If you are pulling Parsteel, Tritanium, or Dilithium for build queues or research, the captain seat pulls hardest there because the captain bonus and the bridge bonus both apply.
The second is general mining across any other resource. The bridge ability does not care what you are mining, so he slots into a Tritanium ship, a gas ship, or a crystal ship without losing value. He pairs well with the other Borg miners and with classic mining bridge officers when you want to push throughput on a route.
The third is Unimatrix Twelve crews when the rest of your Borg roster is at rank. The synergy ring is wide, so the moment you have two other Unimatrix Twelve officers with a high synergy percentage, your crew snaps into place with very little effort. That makes him a comfortable default in any mining crew that includes other Borg officers.
How to get Ten of Eleven shards
Ten of Eleven is a Borg-track Epic officer, so his shards turn up alongside the rest of the Unimatrix Twelve set: Borg-themed events, Borg recruit drops, and the Borg recruitment store when the store cycles in. The store and event lineup rotate often, so check the current rotations 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, Active Nanoprobes, and Engineering Badges on the usual Borg-officer schedule. The Active Nanoprobe wall at Commander V (around 1.1 million) is the most common bottleneck for accounts that are not deep into Borg progression yet, and the Engineering Badge requirement scales with each rank.
Character traits
Ten of Eleven has three traits that unlock in order. Assimilated comes first and is cheap to finish. Miner opens after Assimilated wraps, with a noticeable price dip at Level 2 before the cost climbs again. Fluffy is the long haul: nine levels deep, with the back half of the tree pulling more Officer XP than every earlier level combined.
| Trait | Per-level Officer XP |
|---|---|
| Assimilated (3 levels) | 1,500 / 2,700 / 3,800 |
| Miner (4 levels) | 7,650 / 6,000 / 7,000 / 8,850 |
| Fluffy (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, Fluffy is the trait to plan around. Level 9 alone costs 107,000, which is more than Assimilated, Miner, and the first six levels of Fluffy put together. Unlocking the next trait requires finishing the previous one, so you cannot skip ahead to Fluffy without paying through Assimilated and Miner first.
Synergy officers and crew building
His class synergy bonuses, when he is captain, are Command 75%, Engineering 25%, and Science 75%. That pattern is the same shape several Borg captains share: pairing him with Command or Science officers in the other seats pays out more than a same-class Engineering pair. For a pure mining crew that is fine, because most of the heavy Borg mining and economy hitters land in those classes anyway.
Named synergy officers (current as of the latest data):
| Officer | Synergy |
|---|---|
| One of Eleven | 75% |
| Two of Eleven | 75% |
| Three Of Eleven | 75% |
| Four of Eleven | 25% |
| Five of Eleven | 25% |
| Six of Eleven | 75% |
| Seven of Eleven | 75% |
| Eight of Eleven | 25% |
| Nine of Eleven | 75% |
| Eleven of Eleven | 75% |
| Hugh | 25% |
| Ghalenar | 75% |
| Borg Queen | 75% |
| Dezoc | 75% |
| Gossa | 25% |
Most of his Unimatrix Twelve crewmates land at 75%, which is the practical reason Borg mining crews glue together so cleanly. Any two of the 75% officers in the other seats keep the synergy multiplier high while you build whatever mining shape you actually need. The 25% slots are useful to know about for crew swapping when the 75% options are not available, but they are not where the value sits.
Frequently asked questions
Is Ten of Eleven worth the rank-up?
If you spend a meaningful share of your week mining station resources, yes. The bridge bonus climbs from 80% to 160% between Ensign I and Commander V, so every promotion translates directly into faster mining runs. Accounts that already have a strong mining-officer roster should weigh the rank-up against other officers competing for the same Active Nanoprobes and Engineering Badges.
Where do you get Ten 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 Ten of Eleven best on?
Whichever mining ship you take out for long sessions. Because the bridge bonus is unconditional, the ship matters less than the activity. For Parsteel, Tritanium, or Dilithium runs, putting him in the captain seat on a station-resource miner stacks both bonuses on the same hold.
Does his captain ability work on gas or crystals other than Dilithium?
No. Multiplicative Extraction only covers Parsteel, Tritanium, and Dilithium. For Raw Gas, Raw Crystal, or other resources, the bridge ability still applies, but the captain bonus does not.
Is he useful in combat?
No. Neither the captain ability nor the bridge ability does anything in PvP, hostile grinds, station strikes, or Armadas. Use him for mining, then swap him out before you undock for combat.
If your account is mid-game and you have any meaningful mining backlog, Ten of Eleven earns his slot quickly once he is at Lieutenant JG II or higher. If you are not running a lot of mining and have other Borg officers competing for the same shards, save the Engineering Badges for an officer whose ability fires in more of your activities first.
