Who Arrock is and why players want him
Arrock is a rare Ferengi officer in Star Trek Fleet Command, slotted into the Ferengi Conglomerate group and built around one specific job: mining Concentrated Latinum faster than anything else in the game. His captain ability sits in a small category of mining specialists with an outsized buff to a single resource, and his officer ability adds a second layer of mining speed on top.
That narrow focus is the point. If you mine Concentrated Latinum regularly, he pays for himself. If you don’t, he stays on the bench. This guide covers what Arrock does, where he fits in a fleet, how synergy stacks with his Ferengi peers, and what to think about before chasing his shards.
Star Trek background
Arrock is an STFC-original character, not a canonical figure from any Star Trek series or film. His in-game lore places him in the Ferengi Conglomerate alongside other merchants and acquisition specialists, with a backstory that frames him as the elder of two brothers mentored by Quark, the Deep Space Nine bartender. The game describes Arrock as impulsive and stubborn, traits that make him a poor business owner but a fierce negotiator who tends to walk away on the winning side of a deal.
The wider Ferengi context is the part players will recognize. The Ferengi are Trek’s mercantile species, known for the Rules of Acquisition and a culture that treats profit as a civic virtue. STFC leans into that backdrop for the Ferengi Conglomerate roster, and Arrock fits the mold as a young trader trying to build a name in a market full of sharper operators.
Role in STFC
Arrock is a Science-class officer designed for one job: mining Concentrated Latinum. Concentrated Latinum is the upgraded version of standard Latinum, found in higher warp systems and used to buy premium items at the Ferengi store, including officer shards. Faster mining means more Latinum per hour, more store purchases, and faster progress on Ferengi-side projects.
He is not a combat officer. He has no listed PvP or PvE buffs, no armada bonus, and no station defense application. Bringing him on anything other than a Concentrated Latinum mining run is a waste of a seat.
Captain ability and officer ability
Arrock’s captain ability is called Exploit Market Opportunities. As captain, he increases mining speed for Concentrated Latinum by 6,500% at rank one, as of the latest game data. This is a single-resource buff, not a generic mining bonus, so it only fires when the ship is collecting Concentrated Latinum. The buff continues to scale with rank-ups, but the exact per-rank values are best confirmed in-game before planning a heavy mining session, since single-resource captain abilities are sometimes adjusted between patches.
His officer ability is Diversify, which adds a general mining speed buff when he sits on the bridge of any ship. The bonus scales with promotion rank: higher ranks produce a larger Diversify buff. The two abilities stack in the obvious way. As captain on a Concentrated Latinum run, Arrock contributes both the headline captain buff and his bridge contribution. If a different miner captains the ship, you can still bring Arrock as crew to add the Diversify bonus on top of whatever the captain is doing.
Where Arrock shines
The clearest use case is a dedicated Concentrated Latinum mining hauler. Drop him in the captain seat of a Science-class miner, fill the bridge with synergy officers (covered below), and route the ship to a Concentrated Latinum node in a high enough warp system. The captain ability does almost all the heavy lifting; the rest of the bridge multiplies it.
He also fits players who run multiple Latinum farms in parallel. If you already have a Quark or Rom crew working other Ferengi resources, Arrock becomes the dedicated Concentrated Latinum specialist that frees the other officers up for whatever they were already doing.
Outside that lane, he sits on the bench. There is no general-purpose miner role for him because the captain bonus only applies to one specific resource, and the Diversify officer bonus on its own is not large enough to justify a bridge seat over a stronger general miner.
How to get Arrock
Arrock is a rare officer with a manageable total shard cost to reach max rank. Like most Ferengi Conglomerate officers, his shards rotate through the Ferengi store, recruit-token tables, and occasional events. Check the current Ferengi store offerings and event rotations before committing chests or tokens to a long shard grind.
From recruitment through max rank he needs 546 shards in total, broken out by rank as follows (current as of the latest game data):
| Rank | Shards to promote into this rank |
|---|---|
| 1 | 36 |
| 2 | 55 |
| 3 | 95 |
| 4 | 145 |
| 5 | 215 |
The early ranks are cheap, so getting Arrock to a usable rank is fast once his shards appear in your store. The last promotion (rank 5) is the longest grind, but it isn’t required for him to function as a Concentrated Latinum specialist.
Synergies
Arrock’s synergy group is the Ferengi Conglomerate. The four named synergy officers are Fess, Quark, Rom, and Cath. Pairing Arrock with any of these officers on the same bridge applies a substantial synergy bonus, listed at 3,000% per officer on the current data.
For a Concentrated Latinum mining build, the typical crew is Arrock as captain with Quark and Rom on the bridge. Both are mining-focused Ferengi officers, both sit in the same synergy group, and their abilities slot cleanly alongside Arrock’s. Fess and Cath are the alternate fills when one of the others is busy on another job, or when you want a second mining ship running in parallel.
For class synergy, Arrock’s seat applies a Science-class bonus, and pairing him with other Science-class officers in the right seats unlocks additional class synergy on top of the named-officer bonus. The sources don’t list specific Command, Engineering, and Science percentages for Arrock, so think of class synergy as a multiplier you pick up when you fill bridge seats with the right classes, not a fixed number to chase.
Character traits
Arrock has two traits in his unlock progression: Uncompromising and Reliable. They unlock in sequence, with the second one becoming available only after the first is fully leveled. Trait effects vary by level and require trait XP to unlock, which is gathered through trait packs and event rewards. There is nothing unusual about the trait costs for an officer in his rarity tier, so treat trait unlocks as a slow background project rather than a priority.
Frequently asked questions
Is Arrock worth getting?
If you mine Concentrated Latinum at any volume, yes. The captain ability buff for Concentrated Latinum is among the largest single-resource mining bonuses in the game, and even a low-rank Arrock outperforms a generic miner in that one job. If you don’t mine Concentrated Latinum, skip him and put your shard budget on an officer who supports a role you actually play.
Where do you get Arrock shards?
The most consistent source is the Ferengi store, where his shards rotate through alongside other Ferengi Conglomerate officers. He also appears in recruit token rolls and shows up in event store rotations from time to time. Check the current event and store availability before grinding any one source.
What is the best ship for Arrock?
Any Science-class miner you have already upgraded for the warp tier where Concentrated Latinum is mined. Arrock’s captain ability applies to the mining speed of the ship he is captaining; the ship itself just needs the cargo and warp range to reach the node and haul the resource home.
Should Arrock be captain or crew?
Captain. His mining bonus sits on the captain ability, not the officer ability, so he has to be in the captain seat to apply the headline Concentrated Latinum buff. If you put him on the bridge under a different captain, you only get the smaller Diversify bonus.
Does Arrock work with other mining crews?
His captain bonus only applies to Concentrated Latinum, so he isn’t a fit for crystal, ore, or gas mining setups. For those resources you would build around different specialists. Inside the Ferengi Conglomerate roster, his synergy stack with Quark, Rom, Fess, and Cath gives you a tight Latinum-focused mining crew.
Final notes
Arrock is a single-purpose officer with a clear job. If Concentrated Latinum is part of your weekly routine, getting him to a usable rank pays back quickly through faster mining cycles and more store purchases. If you don’t touch Concentrated Latinum, there is no reason to chase his shards beyond completionism. Either way, his cost-to-effect ratio at the first couple of ranks is good enough that he is worth picking up opportunistically when his shards happen to be on sale in the Ferengi store.
