The Cost of Obsession is a Borg Arc mission in Star Trek Fleet Command where you search for a new piece of Borg technology. It is listed at recommended level 1, starts at warp 1 and needs warp 18 to complete. Everything happens around Pasadoran: you visit a colony, find the organization behind it, clear 10 hostiles of level 26 or higher, then decide whether to attack the colony or abandon Dalen. Attacking pays 75,000 Dilithium; walking away pays 182,000 Officer XP.
The Cost of Obsession objectives
The first five steps are shared:
- Visit the Colony. Location: Pasadoran.
- Find the organization. Location: Pasadoran.
- Defeat 10 Hostiles of Level 26 or higher.
- Return to the colony. Location: Pasadoran.
- Attack the colony?
That last question is a choice split with two very different outcomes.
Path A: attack the colony
- Defeat the colony leader. Location: Pasadoran. Enemy strength is roughly 296,419.
- Return to your Station.
Path B: abandon Dalen
- Return to your Station.
Path A adds a serious fight at close to 300,000 strength. Path B skips combat entirely and sends you straight home.
Where and what warp
The mission picks up at warp 1 and needs warp 18 to complete. Pasadoran is the only named system; the hostile count does not name one. Both paths end with a return to your station.
The recommended level is 1, but the level 26 hostiles and, on Path A, the colony leader are what decide when you can finish it.
The Cost of Obsession rewards
| Path | Extra objectives | Reward |
|---|---|---|
| Path A: attack the colony | Defeat the colony leader (about 296,419) | 75,000 Dilithium |
| Path B: abandon Dalen | None | 182,000 Officer XP |
Either path unlocks the next mission in the Borg Arc.
Which path to pick
Path B is the easier choice and, for most players, the better one. It skips the colony leader fight and pays 182,000 Officer XP, which goes straight into levelling your crew.
Path A makes sense if you need Dilithium more than officer levels and your ship can beat a target at nearly 300,000 strength.
How it fits the Borg Arc
| Mission | Warp to complete | Story | Rewards |
|---|---|---|---|
| Over the Line | 18 | Steal the drone back from Starfleet | 400 Ultra Recruit Token or 20 15 Minute Repair Speed Up, depending on your choice |
| The Cost of Obsession | 18 | Search for the new Borg technology | 75,000 Dilithium or 182,000 Officer XP, depending on your choice |
Both missions finish at warp 18 and both end in a choice, so the same ship and the same planning carry straight over from Over the Line.
Tips
Clear the 10 hostiles with a combat ship before you return to the colony. They must be level 26 or higher, so pick your targets accordingly.
If you plan to attack, repair before you return to Pasadoran for the final step. The colony leader is the hardest fight in the mission.
Dalen also appears earlier in the arc in Swift Reprisal. The previous mission is Over the Line and the next is Smokescreen. Every mission by level is on the mission guide.
