Arknights: Endfield introduces a deep economy system through Stock Redistribution, a marketplace integrated into the Regional Development Management. This feature lets players spend region-specific Stock Bills to purchase essential items like Headhunting Permits, upgrade materials, and gifts, while also enabling a stock market-style trading mechanic with Elastic Goods for profit. Mastering it accelerates progression, from outpost upgrades to operator enhancements.
Unlocking Stock Redistribution
To access this system, reach Player Level 15 by spending Sanity on node tasks. Then, complete the "Restart Area Stock Redistribution" quest chain in Valley IV's The Hub:
- Part I: Head to Worker Dorms and speak to Lucky Carrot (the rabbit NPC). Authorize the system to unlock the initial Staple Goods shop. Buy the Mr. Rammu gift as part of the tutorial.
- Part II: Farm 4,000 Valley Stock Bills via outpost trades, then upgrade the terminal at Lucky Carrot.
Rewards include Oroberyl, T-Creds, Combat Records, and Arms INSP Kits. This sets up your first terminal.
Key Currencies: Stock Bills
Stock Bills are region-locked currencies:
- Valley Stock Bills: Used in Valley IV terminals (e.g., The Hub, Originium Science Park).
- Wuling Stock Bills: For Wuling areas like Jingyu Valley.
They cannot cross regions. Earn them primarily through:
- Outpost Trading: Trade excess materials from high-level outposts for the best yields. Assign operators with bill bonuses.
- Elastic Goods Flipping: Buy low, sell high (detailed below).
- Depot Node Deliveries: Transfer jobs to friends for mutual Stock Bill gains, rather than completing solo.
- Combat and Missions: Minor drops from enemies and events.
Prioritize outposts for daily farming.
Staple Goods: Permanent Purchases
Staple Goods offer fixed-price items that restock with terminal upgrades. Buy them before they sell out, as limits are strict. Focus on progression boosters like permits and materials.
| Item | Cost (Valley Stock Bills) |
|---|---|
| Basic HH Permit | 2,000 - 8,000 |
| T-Creds | 400 - 8,000 |
| Arms INSP Kit | 400 |
| Protodisk | 1,000 - 10,000 |
| Cast Die | 1,000 - 10,000 |
| Fortmaker | 1,000 |
| Opus: The Living | 4,000 |
| Finishing Call | 8,000 |
| Seeker of Dark Lung | 2,000 |
| Keen Valley Detector | 1,000 - 5,000 |
| Keen Valley Compass | 1,000 - 5,000 |
| Tastes of V4: Workers Borscht | 2,500 |
| Training Material: Of Wildlife and Aggeloi | 15,000 |
| Mr. Rammu | 100 |
| Operator Gifts | 100 - 300 |
Best Priorities: HH Permits for pulls, high-tier materials (Protodisk, Cast Die), and gifts for operator bonds. Discounts improve with upgrades (e.g., -90% early on).
Elastic Goods: The Stock Market Mini-Game
This tab simulates trading: Prices fluctuate daily (reset ~04:00 UTC+8). Compare Recommended Price (market value) to Total Cost (your buy/sell price).
- Buy: If Recommended Price < Total Cost (red down arrow, e.g., -40%+ discounts). Stock up on limits.
- Sell: If Recommended Price > Total Cost (green up arrow, e.g., 200%+ gains). Hold for peaks.
Visit friends' terminals for price variances and sell for massive profits. Add friends via the Friends Board for more options. Daily limits reset, so check post-reset.
Upgrading Terminals
Interact with terminals (via Lucky Carrot or directly) to upgrade using Stock Bills. Focus on The Hub first:
| Upgrade | Cost (Valley Stock) | Unlocks |
|---|---|---|
| 0 → 1 | 500 | Staple restock |
| 1 → 2 | 4,500 | Elastic Goods + restock |
| 2 → 3 | 33,000 | Higher daily limits |
| 3 → 4 | 380,000 | Max restocks/limits |
Other locations: Originium Science Park (Mountain Slope), OMV Dijiang (Kernel Sector), Jingyu Valley (Wuling).
Advanced Tips and Strategies
- Daily Routine: Log in post-reset, buy deep-discount Elastic Goods, sell holdings to friends, trade outposts.
- Friends Matter: Build a list for cross-world sales and depot transfers. Buy cheap locally, sell high elsewhere.
- Resource Balance: Farm bills before big upgrades to avoid shortages.
- Endgame Focus: In Wuling, prioritize for Engraving Permits and Artificing Catalysts.
- Factory Synergy: Produce high-value Elastic Goods like HC Valley Battery for flips.
