What to know
-
Elastic Goods prices fluctuate daily, and prices also vary between player worlds, which is what makes trading profitable.
-
Unlock Elastic Goods by upgrading Lucky Carrot’s Stock Redistribution hub to Level 2 (costing 500 to unlock the hub, then 4,500 more to reach Level 2).
-
Your daily purchase limit restricts how many Elastic Goods you can buy, so you want the best profit per item, not just the biggest discount percent.
-
Always compare each item’s resale value across friends; if everyone has the same “cheap” item, profit can be low.
Arknights: Endfield’s Elastic Goods loop is essentially legal arbitrage: you’re taking advantage of daily price swings and cross-world price differences to convert time and planning into Stock Bills.
| Topic | What it means for you |
|---|---|
| Requirement | Lucky Carrot unlocked at level 14 via “Restart Area Stock Distribution I.” |
| Unlock cost | 500 Stock Bills to unlock his hub; +4,500 Stock Bills to upgrade to Level 2 and open Elastic Goods. |
| Core method | Buy discounted Elastic Goods in your world, sell the same goods in a friend’s world where the price is higher. |
| Key constraint | Daily purchase limit (commonly 30 by default, increased via upgrades). |
| What to optimize | Profit per item (absolute Stock Bills gained per unit), since your purchases are capped. |
Location in-game
You’ll interact with Stock Redistribution either through Lucky Carrot (the NPC tied to the Stock Redistribution hub) or via the Stock Redistribution terminal on the Dijiang, then use “Friend’s Price” to check what other players’ worlds pay for the same Elastic Good.
How to farm Stock Bills with Elastic Goods
Step 1: Unlock Lucky Carrot and Stock Redistribution
Reach level 14 and complete the quest “Restart Area Stock Distribution I”.
Now Lucky Carrot will become available.
Step 2: Upgrade to unlock Elastic Goods
Pay 500 Stock Bills to unlock Lucky Carrot’s hub.
Then spend 4,500 more to upgrade the hub to Level 2.
This unlocks Elastic Goods.
Step 3: Open Elastic Goods and scan today’s prices
Go to Stock Redistribution and open the Elastic Goods tab to see which items are discounted (often indicated with down/discount arrows) versus overpriced (up arrows).
Step 4: Check “Friend’s Price” before you buy
For each Elastic Good you’re considering, use the Friend’s Price option to see what your friends’ worlds pay for that exact item.
Step 5: Choose items by profit per item, not discount percent
Prioritize the highest expected Stock Bills gained per unit (sell price − buy price), because your daily buy count is limited, and a smaller % margin can still be better if the item’s base price is higher.
Step 6: Buy your chosen Elastic Goods in your world (up to the daily cap)
Purchase your best candidates while they’re low in your world, keeping an eye on your remaining daily purchase allowance.
Step 7: Visit the friend with the highest sell price
Travel to the friend whose world offers the best resale price for the item(s) you bought.
Step 8: Sell at their Stock Redistribution terminal
Sell the Elastic Goods through Stock Redistribution in your friend’s world to capture the price difference as profit in Stock Bills.
Step 9: Repeat across multiple items (and multiple friends if needed)
If one item doesn’t have a strong spread, move to the next Elastic Good and repeat the buy → highest friend price → sell loop.
Step 10: Increase your daily ceiling over time
Upgrade the Stock Redistribution terminal to raise your daily Elastic Goods purchase limit (commonly starting at 30 per day, then increasing with upgrades), which scales this method’s payout.
Practical trading rules that stop wasted runs
If you want to stop wasted runs, follow these trading rules:
Don’t assume the cheapest item is the best flip
If everyone sees the same “cheap” item, the resale prices across friends can be similarly low, shrinking your spread.
Treat your friend list like a price scanner
More friends means more chances that someone’s world is offering a high sell price for the item you can buy cheap today.
Hold items if you can’t find a good sell today
Elastic Goods you already bought don’t disappear immediately, so you can wait until a friend shows a much better sell price instead of forcing a low-profit sale.
Once Elastic Goods are unlocked, your Stock Bills income becomes a daily routine: check spreads, buy selectively, and sell where your friends pay the most.
