What is Operator Liaison?
Operator Liaison is a passive bonus system that lets you assign operators to outposts. When an operator's attributes match the outpost's requirements, you receive bonus rewards on every trade.
How it Works
- 1. Open any outpost menu -- Access the trade interface
- 2. Assign one operator to the Liaison slot -- Choose from your roster
- 3. If attributes match requirements -- Bonus activates on trades
- 4. Each matching attribute -- Has a 20% trigger chance per trade
Free Currency
Bonus Stock Bills and Prosperity on every trade with zero cost or cooldown.
Passive Income
Bonuses compound over time across hundreds of daily trades.
Stacks Normally
Liaison bonuses add on top of standard outpost trade rewards.
The 3 Liaison Bonus Types
Each bonus type is linked to a specific operator attribute. Matching the attribute gives a 20% trigger chance for bonus rewards on every trade.
| Bonus Type | Trigger Attribute | Effect | Priority |
|---|---|---|---|
| SAR Response | Faction | 20% chance to earn 1 extra Prosperity per trade | Medium |
| Turn Scrap to Treasure | Hobbies | 20% chance to earn 1 extra Stock Bill per trade | High |
| Survival Knowledge | Expertise | 20% chance to earn 1 extra Stock Bill per trade | High |
Stock Bill Bonuses Prioritized
If you can only optimize one bonus per outpost, prioritize Hobbies or Expertise matches over Faction. Stock Bills have direct spending value in Stock Redistribution, Depot_node upgrades, and weapon stores. Prosperity is valuable mid-game for AIC expansion, but Stock Bills unlock immediate progression tools.
Bonuses Trigger Independently
An operator matching 2-3 attributes can trigger multiple bonus types on the same trade. Each bonus rolls its 20% chance separately. For example, an operator matching both Faction and Hobbies has a 20% chance for SAR Response AND a separate 20% chance for Turn Scrap to Treasure.
Trading Profit Bonus (20% Boost)
The 20% trading bonus is mathematically significant because it is applied after the outpost's base pool is exhausted. If an operator sells $100,000 SB worth of goods to an outpost, a matching liaison provides a statistical 20% boost, effectively generating $20,000 extra Stock Bills "out of thin air." This bonus is independent of the outpost's local funds, allowing the operator to extract more money than the outpost technically contains.
| Outpost | Recommended Liaison (Accumulation) | Recommended Liaison (Trading) | Bonus Type |
|---|---|---|---|
| Refugee Camp | Yvonne | Laevatain / Tangtang | Trade Profit |
| Infra-Station | Yvonne | Yvonne / Rossi / Tangtang | Trade Profit |
| Reconstruction HQ | Yvonne | Gilberta / Alesh | Trade Profit |
| Sky King Flats | Tangtang | Tangtang / Ardelia | Prosperity / Trade |
| Remediation Station | Zhuang Fangyi | Zhuang Fangyi / Chen Qianyu | Trade Profit |
Understanding the 20% Trading Bonus
Accumulation vs Trading: Some operators are better for passively accumulating Prosperity (SAR Response bonus), while others excel at maximizing immediate trading profits. The table above separates these roles by outpost.
Strategic Rotation: Consider assigning a Prosperity-bonus operator while the outpost stockpiles bills, then swapping to a Trading-bonus operator just before selling high-value goods for maximum efficiency.
All 5 Outpost Locations & Requirements
Each outpost has specific attribute requirements for triggering liaison bonuses. Matching any one of the three attributes activates the corresponding bonus type.
| Outpost | Region | Unlock Requirement | Currency |
|---|---|---|---|
| Refugee Camp | Valley Pass | "Building an Outpost" exploration | Valley Stock Bills |
| Infra-Station | Originium Science Park | "Outpost: Infra-Station" after "Cross the Science Park" | Valley Stock Bills |
| Reconstruction HQ | Power Plateau | "Outpost: Reconstruction HQ" at Authority Level 34 | Valley Stock Bills |
| Sky King Flats | Jingyu Valley (Wuling) | Authority Level 43+ after "Where Danger Sleeps" | Wuling Stock Bills |
| Remediation Station | Marker Stone (Wuling) | Version 1.2 "At the Wake of Spring" | Wuling Stock Bills |
Attribute Requirements
Each outpost requires specific operator attributes (Faction, Hobbies, or Expertise) to trigger liaison bonuses. Refugee Camp requirements are fully documented below. For other outposts, check the in-game liaison assignment menu to view attribute requirements, then match operators from your Trust system.
Refugee Camp Operator Assignments (Complete)
Refugee Camp is the first outpost you unlock and has fully documented attribute requirements. This section provides a complete operator tier list with all available operators and their bonus potential.
Outpost Requirements
Region -- Valley Pass
Unlock -- Complete "Building an Outpost" exploration mission after "Valley Reboot"
Faction -- Rhodes Island
Hobbies -- Creative
Expertise -- Situation Analysis
Tier 1 - Best Matches (Match 2 Attributes)
| Operator | Rarity | Faction | Hobbies | Matches | Bonuses |
|---|---|---|---|---|---|
| Laevatain | 6★ | Rhodes Island ✅ | Creative ✅, Lifestyle | 2/3 attributes | SAR Response + Turn Scrap to Treasure |
Why Laevatain is Best
Matches both Hobbies (Creative) AND Faction (Rhodes Island). Triggers both SAR Response (+1 Prosperity) and Turn Scrap to Treasure (+1 Stock Bill) bonuses with independent 20% trigger chances. 6★ rarity with strong utility across other game systems.
Tier 2 - Strong Matches (Single Strong Match)
| Operator | Rarity | Faction | Hobbies | Match | Bonus |
|---|---|---|---|---|---|
| Gilberta | 6★ | Rhodes Island ✅ | Fashion, Culture | Faction | SAR Response |
| Ardelia | 5★ | Rhodes Island ✅ | Lifestyle, Nature | Faction | SAR Response |
| Perlica | 5★ | Endfield Industries | Creative ✅, Lifestyle | Hobbies | Turn Scrap to Treasure |
Gilberta (6★): Strong roster utility. Faction match provides +1 Prosperity. Good for mid-game AIC expansion focus.
Ardelia (5★): Solid combat utility. Faction match provides +1 Prosperity. Good backup when Laevatain/Gilberta unavailable.
Perlica (5★): Excellent Dijiang operator with strong manufacturing bonuses. Hobbies match provides +1 Stock Bill.
Tier 3 - Filler/Backup (Single Weak Match)
| Operator | Rarity | Faction | Hobbies | Match | Bonus |
|---|---|---|---|---|---|
| Antal | 4★ | Endfield Industries | Creative ✅, Mind Honing | Hobbies | Turn Scrap to Treasure |
| Fluorite | 4★ | Endfield Industries | Creative ✅, Nature | Hobbies | Turn Scrap to Treasure |
| Snowshine | 5★ | Rhodes Island ✅ | Sports, Charity | Faction | SAR Response |
| Pogranichnik | 5★ | Rhodes Island ✅ | Culture, Mind Honing | Faction | SAR Response |

| Tangtang | 6★ | Endfield Industries | Creative ✅, Nature | Hobbies | Turn Scrap to Treasure |
| Rossi | 6★ | Endfield Industries | Nature, Sports | Expertise | Survival Knowledge |
Tier 3 Notes
Use these operators when Tier 1-2 are unavailable or assigned elsewhere. Single attribute match still provides 20% bonus chance. 4★ operators are generally weaker roster members overall. Keep roster depth to allow rotation across 4 outposts.
Tangtang (6★): Matches Creative hobby for +1 Stock Bill bonus. Good backup for Refugee Camp, excellent for Infra-Station (matches Endfield Industries faction).
Rossi (6★): Matches Situational Analysis expertise for +1 Stock Bill bonus. Unique expertise match makes her valuable when Laevatain is assigned elsewhere. Also matches Endfield Industries faction at Infra-Station.
Pro Tip: Refugee Camp Strategy
Prioritize Stock Bill bonuses (Hobbies match) over Prosperity for Refugee Camp. Early game, Stock Bills are your primary bottleneck for Depot Node upgrades and Stock Redistribution terminal unlocks. Assign operators with "Creative" hobby: Laevatain (best), Perlica (Tier 2), Antal/Fluorite/Wulfgard (Tier 3).

How to Check Operator Attributes
Open the Trust system from the main menu to view operator attributes. All three attribute types (Faction, Hobbies, Expertise) are displayed in each operator's profile.
Steps to Find Attributes
- 1. Open the main menu -- Press the menu button or access key
- 2. Navigate to "Trust" tab -- The Trust system is available from the start
- 3. Select any operator -- Choose from your recruited roster
- 4. View their profile -- Three attribute tabs are displayed: Faction, Hobbies, Expertise
Faction
Single value displayed near the operator's portrait. Examples: Rhodes Island, Endfield Industries, UWST, TGCC, HAS, Ses'qa, Hannabit Circuit.
Hobbies
Two values per operator. Examples: Creative, Sports, Technology, Lifestyle, Nature, Fashion, Culture, Charity, Fine Arts, Mind Honing.
Expertise
Single value in operator details section. Examples: Situation Analysis, Engineering, Medical, Combat, Research.
Important: One Operator Per Outpost
You cannot assign the same operator to multiple outposts simultaneously. Each outpost requires its own dedicated liaison. Plan your assignments strategically across your 4 outposts based on operator availability and attribute matches.
Common Mistakes & How to Avoid Them
1. Not Assigning Any Operator
Free 20% bonus chance on every trade is passive income. Even a single attribute match provides value over time. The bonus compounds across dozens of daily trades. Every outpost without a matched liaison is leaving currency on the table.
2. Assigning High-Value Operators to Wrong Outposts
Laevatain matches both Faction and Hobbies at Refugee Camp. Assigning her to a different outpost wastes her double-match potential. Prioritize Tier 1 operators for outposts where they match the most attributes.
3. Prioritizing Prosperity Over Stock Bills Early Game
Stock Bills unlock Depot capacity, terminal upgrades, and Stock Redistribution purchases. These provide immediate progression value. Prosperity expands your AIC area, which matters more mid-game when you have better factory layouts. Prioritize Stock Bill bonuses (Hobbies/Expertise) in early game.
4. Checking Only Faction Attribute
Many players assume Faction is the most important. Outpost-specific requirements may prioritize Hobbies or Expertise. Check all three attribute types before choosing an operator. The Trust system makes this easy.
5. Ignoring Expertise Attribute
Expertise is often overlooked because it's one value per operator (vs. two for Hobbies). But Expertise matches provide +1 Stock Bill, which has direct value. Don't ignore operators with matching Expertise even if they don't match Faction or Hobbies.
6. Not Rotating Liaisons Across Outposts
One operator can only be assigned to one outpost at a time. If you have 4 outposts but only 2 good liaisons, plan rotation schedules. Check daily trade volume at each outpost -- assign your best operators to highest-volume outposts.
7. Forgetting to Check Requirements in Game
The Liaison assignment menu displays exactly which Faction, Hobbies, or Expertise values trigger bonuses. Don't rely solely on external guides -- requirements may change or differ in future updates. Always verify in-game.
8. Matching Wrong Operator Attributes
Double-check that you're assigning the RIGHT operator for the specific outpost. Refugee Camp requires Rhodes Island faction, Creative hobby, or Situation Analysis expertise. A Rhodes Island operator without Creative or Situation Analysis won't trigger anything at Refugee Camp.
9. Regularly Re-evaluating Assignments
As your operator roster grows through gacha and recruitment, re-evaluate your liaison assignments. A newly recruited operator may have better attribute matches than your current assignments. Periodic checks ensure maximum efficiency.
