## 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. 1. **Open any outpost menu** \-- Access the trade interface
2. 2. **Assign one operator to the Liaison slot** \-- Choose from your roster
3. 3. **If attributes match requirements** \-- Bonus activates on trades
4. 4. **Each linked reward point** \-- Has a 20% chance to generate one more

### 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 Reward Slots

Each station has a Prosperity slot and two Stock Bill slots. The display names and exact requirements vary, but matching a requirement always activates its linked reward bonus.

| Reward Slot              | Typical Requirement                   | Effect                                                                           | Priority |
| ------------------------ | ------------------------------------- | -------------------------------------------------------------------------------- | -------- |
| Prosperity bonus         | Faction or station-specific expertise | Every linked Prosperity point has a **20% chance to generate 1 more**            | Medium   |
| Trade Stock Bill bonus   | Hobbies                               | Every linked traded Stock Bill has a **20% chance to generate 1 more**           | High     |
| Outpost Stock Bill bonus | Expertise                             | Every linked outpost-produced Stock Bill has a **20% chance to generate 1 more** | High     |

SAR Response, Turn Scrap to Treasure, and Survival Knowledge are the Refugee Camp names. Xiranflow Cloudseeder uses Xiranite Scripting, Nature's Overwatch, and Mastery of Pen and Blade.

### 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](https://endfieldhub.org/guides/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 requirements activates multiple reward slots. Every linked Prosperity or Stock Bill point rolls its own 20% chance independently, so a 3/3 liaison maximizes all three bonuses at once.

## 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               | Best Liaison  | Matches | Best Backup            |
| --------------------- | ------------- | ------- | ---------------------- |
| Refugee Camp          | Laevatain     | 3/3     | Rossi or Perlica (1/3) |
| Infra-Station         | Yvonne        | 3/3     | Chen Qianyu (2/3)      |
| Reconstruction HQ     | Gilberta      | 3/3     | Pogranichnik (2/3)     |
| Sky King Flats        | Tangtang      | 3/3     | Lifeng or Arcane (2/3) |
| Cardiac Remediation   | Zhuang Fangyi | 3/3     | Arcane (2/3)           |
| Xiranflow Cloudseeder | Arcane        | 3/3     | Lifeng or Mi Fu (2/3)  |

### Conflict-Free Version 1.4 Lineup

The six best operators are all unique: Laevatain, Yvonne, Gilberta, Tangtang, Zhuang Fangyi, and Arcane can be assigned together without conflicts.

The backup column is evaluated station by station. If a backup is already serving elsewhere, use the next operator who matches that station's Hobby or Expertise Stock Bill requirement.

## All 6 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 |
| Cardiac Remediation Station   | Marker Stone (Wuling)  | Chapter II Process IV: "Free Will"                      | Wuling Stock Bills |
| Xiranflow Cloudseeder Station | Yinglung Pass (Wuling) | Version 1.4 "Outpost: Cloudseeder STN"                  | 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 - Perfect Match (All 3 Attributes)

| Operator  | Rarity | Faction         | Hobbies               | Expertise                              | Matches        | Bonuses                |
| --------- | ------ | --------------- | --------------------- | -------------------------------------- | -------------- | ---------------------- |
| Laevatain | 6★     | Rhodes Island ✅ | Creative ✅, Lifestyle | Situational Analysis ✅, Originium Arts | 3/3 attributes | All three reward slots |

#### Why Laevatain is Best

Matches Rhodes Island faction, Creative hobby, and Situational Analysis expertise. Laevatain activates all three Refugee Camp reward slots and is the clear Version 1.4 best-in-slot liaison.

### Tier 2 - Strong Matches (Single Strong Match)

| Operator | Rarity | Faction             | Hobbies               | Match   | Bonus                  |
| -------- | ------ | ------------------- | --------------------- | ------- | ---------------------- |
| Gilberta | 6★     | Rhodes Island ✅     | Fashion, Culture      | Faction | SAR Response           |
| Ardelia  | 6★     | 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 (6★):** Solid combat utility. Faction match provides the Prosperity bonus. Good backup when Laevatain/Gilberta unavailable.

**Perlica (5★):** Excellent [Dijiang operator](https://endfieldhub.org/guides/control-nexus) 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    | 6★     | Rhodes Island ✅     | Sports, Charity         | Faction   | SAR Response           |
| Pogranichnik | 6★     | Rhodes Island ✅     | Culture, Mind Honing    | Faction   | SAR Response           |
| Wulfgard     | 5★     | Qingbo Stockade     | Creative ✅, Nature      | Hobbies   | Turn Scrap to Treasure |
| Tangtang     | 6★     | Qingbo Stockade     | 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. A single matching requirement still activates its linked 20% expected bonus. Keep roster depth to cover all six outposts.

**Tangtang (6★):** Matches Creative at Refugee Camp, but save her for Sky King Flats where she is the unique 3/3 liaison.  
**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. 1. **Open the main menu** \-- Press the menu button or access key
2. 2. **Navigate to "Trust" tab** \-- The Trust system is available from the start
3. 3. **Select any operator** \-- Choose from your recruited roster
4. 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

Usually two values in the operator details. Examples include Situational Analysis, Constitution, Combat Technique, Agility, and Originium Arts.

### Important: One Operator Per Outpost

You cannot assign the same operator to multiple outposts simultaneously. Version 1.4's six best-in-slot operators are all unique, so the full optimal lineup has no assignment conflicts.

## 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 all three Refugee Camp requirements. Assigning her elsewhere wastes a perfect 3/3 match. Prioritize best-in-slot operators at the stations where they activate the most reward slots.

### 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](https://endfieldhub.org/guides/trust) makes this easy.

### 5\. Ignoring Expertise Attribute

Expertise is often overlooked even though current operators can have multiple expertise values. Expertise checks can activate either Prosperity or outpost-produced Stock Bill bonuses, depending on the station.

### 6\. Not Rotating Liaisons Across Outposts

One operator can only be assigned to one outpost at a time. If you have more unlocked stations than good liaisons, assign your best operators to the highest-volume outposts and rotate backups as needed.

### 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.

## Quick Reference Checklist

## Frequently Asked Questions

### How do you assign operators to outposts in Arknights: Endfield?

Open the outpost menu, select the Liaison slot, and choose an operator from your roster. The operator must be currently at your AIC factory base to be assigned. Any operator can serve as liaison, but only those with matching attributes trigger bonus rewards.

### What is the best operator for Refugee Camp outpost?

Laevatain (6★) is the best choice for Refugee Camp. She matches ALL THREE attributes: Faction (Rhodes Island), Hobbies (Creative), AND Expertise (Situational Analysis). This means she can trigger all three bonus types: SAR Response (+1 Prosperity), Turn Scrap to Treasure (+1 Stock Bill), and Survival Knowledge (+1 Stock Bill). Each bonus has an independent 20% trigger chance.

### What is the best operator for Infra-Station outpost?

Yvonne (6★) is the best choice for Infra-Station. She matches ALL THREE attributes: Faction (Endfield Industries), Hobbies (Technology), AND Expertise (Epiphany). This makes her the only operator who can trigger all three bonus types at this outpost.

### What is the best operator for Reconstruction HQ outpost?

Gilberta (6★) is the best choice for Reconstruction HQ. She matches ALL THREE attributes: Faction (Rhodes Island), Hobbies (Culture), AND Expertise (Originium Arts). She's the only operator who can trigger all three bonus types at this outpost.

### What is the best operator for Sky King Flats outpost?

Tangtang (6★) is the best choice for Sky King Flats. She matches all three requirements: Agility expertise for the Prosperity bonus, Nature hobby for traded Stock Bills, and Combat Technique expertise for outpost-produced Stock Bills.

### What is the best operator for Remediation Station outpost?

Zhuang Fangyi (6★) is the best choice for Remediation Station. She matches ALL THREE attributes: Faction (Hongshan Academy of Sciences), Hobbies (Charity), AND Expertise (Team Management). As a Version 1.2 operator, she's purpose-built for this outpost.

### What is the best operator for Xiranflow Cloudseeder Station?

Arcane (6★) is the perfect Version 1.4 liaison because she matches all three checks: Hongshan Academy of Sciences faction, Nature hobby, and Constitution expertise. Lifeng and Mi Fu are the best 2/3 backups.

### Do Operator Liaison bonuses stack?

One operator can match multiple requirements and activate multiple reward slots. Every linked Prosperity or Stock Bill point independently has a 20% chance to generate one more. However, you cannot assign the same operator to multiple outposts simultaneously.

### Where do you check operator attributes in Arknights: Endfield?

Open the Trust system from the main menu, select any operator, and view their profile. The attributes displayed are Faction (single value like Rhodes Island), Hobbies (two values like Creative and Sports), and Expertise (one or two values like Situational Analysis or Combat Technique + Agility).

### What are the 3 Operator Liaison bonus types?

Every outpost has three reward slots: a Prosperity bonus, a traded Stock Bill bonus, and an outpost-produced Stock Bill bonus. Their names and requirements vary by station. Every linked reward point has a 20% chance to generate one more.
