What Are Outposts?
Outposts are regional trading hubs that form the backbone of Arknights: Endfield's economy. They connect your AIC factory output to the Stock Bill currency system and drive Regional Development progression. Every factory production chain ultimately leads to an outpost trade.
Stock Bill Income
Primary source of Stock Bills, the currency for Stock Redistribution, weapon stores, and Depot upgrades.
Prosperity Growth
Trading earns Prosperity EXP, which expands your AIC build area and improves outpost rewards.
Regional Development
Outpost Prosperity is the largest contributor to Regional Development Level, improving resource quality region-wide.
All 6 Outpost Locations
Outposts unlock as you progress through the story and exploration missions. Version 1.4 adds Xiranflow Cloudseeder Station in Yinglung Pass, bringing the total to six.
| Outpost | Region | How to Unlock |
|---|---|---|
| Refugee Camp | Valley Pass | "Valley Reboot" main mission + "Building an Outpost" exploration |
| Infra-Station | Originium Science Park | "Cross the Science Park" + "Outpost: Infra-Station" exploration |
| Planned Construction Area | Power Plateau | "Eve of Battle" main mission + "Outpost: Reconstruction HQ" (Authority Level 34) |
| Sky King Flats Construction Site | Jingyu Valley (Wuling) | "Where Danger Sleeps" main mission + exploration (Authority Level 43+) |
| Cardiac Remediation Station | Marker Stone (Wuling) | Chapter II Process IV: "Free Will" |
| Xiranflow Cloudseeder Station | Yinglung Pass (Wuling) | Version 1.4 exploration mission "Outpost: Cloudseeder STN" |
Why Multiple Outposts Matter
Each outpost has its own Prosperity track and trade inventory. Running trades at all unlocked outposts multiplies your daily Stock Bill income and Regional Development contribution. Ignoring any unlocked outpost is leaving free currency on the table.

Trading Mechanics & What to Trade
Trading is the core loop of the outpost system. Your AIC factory produces goods, you deliver them to outposts, and they convert into Stock Bills and Prosperity EXP.
How to Trade
- 1. Check requested resources -- Open the outpost menu and see what items are currently requested
- 2. Select quantity -- Use the counting slider to choose how much to trade
- 3. Execute trade -- Confirm to receive Prosperity EXP and Stock Bills
Key mechanic: Outpost Orders pull from your Depot storage automatically. If your Depots are stocked with requested items, orders fulfill themselves without manual intervention.
Best Items to Trade by Stage
| Stage | Best Items | Why |
|---|---|---|
| Early Game | Buck Capsule B | Easy to produce, compact factory layout, Refugee Camp preferred item at Level 2 |
| Mid Game | Buck Capsule B, LC Valley Battery, Ferrium Component | Higher value; LC Battery also powers Thermal Banks; Ferrium for Level 36 gear |
| Late Game | Buck Capsule A, SC Valley Battery | Highest Stock Bill return; Buck Capsule A benefits from Sandleaf Powder multiplication |
Pro Tip: Factory-to-Outpost Pipeline
Your factory and outpost are meant to work as a single system. Build production lines that output directly into Depots connected to outpost orders. The Buck Capsule line is compact and does not require PAC input -- build it in a corner of your AIC and let it run permanently.
Pro Tip: Process Before Trading
A raw Buckflower is worth almost nothing at the outpost. Process it into Buck Capsule B or A first for dramatically higher returns. Always trade finished goods, never raw materials. The farming guide covers production chain details.
Prosperity Leveling
Prosperity Points are earned exclusively through outpost trading. Higher Prosperity Levels unlock increasingly valuable benefits that compound your overall progression.
Benefits of Higher Prosperity
How to Level Prosperity Fast
- 1. Trade high-value items -- Prosperity EXP scales with item value. Buck Capsule A gives far more than Buck Capsule B
- 2. Automate production -- Keep factory lines running and Depots stocked for auto-fulfillment
- 3. Assign matching Liaisons -- The station's Prosperity bonus gives every point a 20% chance to generate one more
- 4. Trade at every outpost -- Each outpost has its own Prosperity track; spread your trades
Operator Liaison Bonuses
Assign operators at outposts to trigger passive trade bonuses. Each bonus type is linked to a specific operator attribute. Matching the right operator to the right outpost adds free rewards to every triggered trade.
| Reward Bonus | Typical Requirement | Effect |
|---|---|---|
| Prosperity | Faction or station-specific expertise | Every Prosperity point earned through trading has a 20% chance to generate 1 more |
| Trade Stock Bills | Hobbies | Every Stock Bill earned through trading has a 20% chance to generate 1 more |
| Outpost Stock Bills | Expertise | Every Stock Bill produced by the outpost has a 20% chance to generate 1 more |
Bonus names vary by station. For example, Xiranflow Cloudseeder calls its three effects Xiranite Scripting, Nature's Overwatch, and Mastery of Pen and Blade.
Best Operator for Every Station (Version 1.4)
These six operators form a conflict-free best-in-slot lineup: every station gets its highest-match liaison without reusing an operator.
| Station | Requirements | Best Liaison | Matches | Best Backup |
|---|---|---|---|---|
| Refugee Camp | Rhodes Island / Creative / Situational Analysis | Laevatain | 3/3 | Rossi or Perlica (1/3) |
| Infra-Station | Endfield Industries / Technology / Epiphany | Yvonne | 3/3 | Chen Qianyu (2/3) |
| Reconstruction HQ | Rhodes Island / Culture / Originium Arts | Gilberta | 3/3 | Pogranichnik (2/3) |
| Sky King Flats | Agility / Nature / Combat Technique | Tangtang | 3/3 | Lifeng or Arcane (2/3) |
| Cardiac Remediation | HAS / Charity / Team Management | Zhuang Fangyi | 3/3 | Arcane (2/3) |
| Xiranflow Cloudseeder | HAS or Cabal / Nature / Constitution | Arcane | 3/3 | Lifeng or Mi Fu (2/3) |
Version 1.4: Why Arcane Is Best for Cloudseeder
Arcane matches all three Cloudseeder checks: Hongshan Academy of Sciences faction, Nature hobby, and Constitution expertise. Lifeng matches HAS + Nature, while Mi Fu matches HAS + Constitution, making either a strong 2/3 backup if you do not own Arcane.
Maximizing Liaison Value
Match count matters more than combat rarity: liaison rewards use profile attributes, not battle strength. Check each profile in the Trust system. If no operator matches all three checks, prioritize the Hobby and Expertise Stock Bill bonuses over the Prosperity bonus.
Regional Development
Regional Development Level (RDL) tracks how much of a region has been developed. It is measured by Regional Development Metric (RDM), earned from multiple sources. Higher RDL improves resource quality across the entire region.
How to Raise RDL
Outpost Prosperity -- The largest RDM contributor. Level up Prosperity through consistent trading.
Missions -- Main story and side missions contribute RDM on completion.
Factory upgrades -- Expanding and upgrading AIC facilities adds RDM.
Mining spots -- Constructing mining rigs across the region adds RDM.
Stock Redistribution terminals -- Upgrading terminals via Lucky Carrot contributes RDM.
Benefits of Higher RDL
| Benefit | Impact |
|---|---|
| Increased facility limits | More ziplines, combat facilities, and infrastructure slots |
| Better resource purity | Ore veins and mining spots produce higher-grade materials |
| Rarer growths | Rare plants and ores spawn more frequently |
| Better outpost protection | Stronger base defense capabilities against enemy attacks |
| Faster gathering | Improved rates when collecting from nodes and rigs |
Stock Bills Economy
Stock Bills are the trade currency earned primarily from outpost orders. They power the Stock Redistribution system and several other progression mechanics. Knowing where to earn them and where to spend them is critical for efficient progression.
Where They Come From
Outpost Orders -- Primary source. Daily trading of factory goods.
Environmental Monitoring -- 50,000+ bills per photo mission.
Elastic Goods Trading -- Buy low / sell high at Stock Redistribution terminals.
Transport Delivery -- Depot Node delivery jobs.
Liaison Bonuses -- Extra bills from matching attribute triggers.
Where to Spend (Priority Order)
- 1. Weekly Stock Redistribution -- Best material rates in the game. Never miss a weekly reset.
- 2. Depot Node upgrades -- Unlock delivery jobs and expand storage capacity.
- 3. Terminal upgrades -- Expand daily Elastic Goods purchase limits.
- 4. Region weapon store -- Region-specific weapons purchasable with local bills.
- 5. Gear Assembly materials -- Valley Stock Bills used in some gear crafting.
Valley vs Wuling Stock Bills
Valley IV outposts earn Valley Stock Bills. The Wuling outpost (Sky King Flats) earns Wuling Stock Bills. Each currency type can only be spent in its respective region's stores and terminals. You cannot convert between them.
Area Defense
Outposts can be attacked by random enemy waves. Defending them requires placing Combat AICs around the outpost perimeter.
Unlock Requirement
Prosperity Level 2 -- Upgrade Refugee Camp to Prosperity Level 2 first.
Quest Completion -- Complete "OD Project Refugee Camp I" to activate defense mechanics.
Defense Basics
Place Combat AICs at chokepoints around your outpost. Defense events trigger randomly and are handled automatically once defenses are set up.
Delay Strategy
If your combat power is low, you can delay progressing Prosperity past Level 1 to avoid triggering Area Defense. This buys time to build stronger Combat AICs.
Common Mistakes & How to Avoid Them
1. Not Trading Consistently
Outpost Orders are daily income. Skipping days means lost Stock Bills and Prosperity that compound over time. Even small daily trades add up significantly.
2. Trading Raw Materials
A raw Buckflower is worth almost nothing. Process it into Buck Capsule B or A before trading for dramatically higher Stock Bill and Prosperity returns. Always trade finished goods.
3. Ignoring Operator Liaison Matching
Free 20% bonus Stock Bills and Prosperity by assigning the right operators. Check their Faction, Hobbies, and Expertise in the Trust system. This is passive income you are leaving on the table by not matching.
4. Spending All Stock Bills on Elastic Goods
Weekly Stock Redistribution staple purchases offer the best rates in the game. Budget for them first, then use leftover bills for Elastic Goods trading.
5. Only Trading at One Outpost
Each outpost has its own Prosperity track. Spread production across all unlocked outposts to maximize total Prosperity and Regional Development contributions.
6. Not Connecting Factory to Depots
Manual trading is slow and easy to forget. Set up Depot Bus connections so outpost orders auto-fill from factory output. This turns trading into a passive income stream.
7. Delaying Outpost Unlocks
Each outpost you unlock adds another income stream and Prosperity track. Prioritize the exploration missions that unlock new outposts as soon as story progression allows.
8. Ignoring Regional Development
Higher Regional Development Level improves resource quality across the entire region. Outpost Prosperity is the largest contributor, so consistent trading directly improves your farming returns.
