What to Know Before You Start
-
The Credit Limit: There is a soft cap of 300 credits that carries over each day. Any credits you hold above this limit will be lost when the daily reset occurs (typically in a few hours depending on your server).
-
Spend Early, Spend Often: To avoid losing credits, always spend your balance down below 300 before logging off.
-
Shop Refreshing: The credit store can be refreshed multiple times a day, allowing you to hunt for high-value items like pulls and rare materials.
-
Friendly Sales: You earn a baseline of credits automatically from goods sold in your base, but these must be manually claimed.
In Arknights: Endfield, credits are a vital resource that grants you access to premium items like Arsenal Tickets (weapon gacha), Ouroberyl, and various character growth materials. While it might seem like they accumulate slowly, there are several streamlined methods to earn over 1,000 credits daily by maximizing social interactions and base management.
Daily Credit Collection Methods
Maximizing your credit income requires a combination of claiming passive rewards and active participation in social systems.
1. Manual Collection and Friendly Sales
The most straightforward method is to check your credit store interface daily.
-
Claim Button: Look for the notification at the bottom of the credit store. This typically yields around 300+ credits per day from your friendly sales rewards.

-
Check Frequently: Since these accumulate throughout the day, checking in the morning and evening ensures you never miss a payout.
Visiting the ships of other players is one of the most underrated ways to boost your income.
-
Assisting Friends: You can perform up to 5 assists per day on friend ships. These include helping with manufacturing cabins or growth chambers.

-
The Reception Room: This is the highest-value assist. Helping a friend find a clue in their reception room grants 50 credits per instance. Completing 5 of these yields an easy 250 credits daily.

-
Fast Navigation: You can jump directly from one friend’s ship to another without returning to your own base, saving significant time.
3. Clue Management and Exchanges
The clue system is the powerhouse of credit generation.
-
Completing the Set: Gathering all seven clues triggers a massive payout of 400 credits. This single action exceeds your daily carry-over cap, so ensure you have items to buy before completing a set.

-
Sending Extra Clues: If you have duplicate clues, send them to your friends. Every clue you gift to a friend provides a small credit bonus, which can be used to push your balance just high enough to afford expensive shop items.

4. Depot Node Delivery Jobs
Depot nodes offer a more active way to earn credits by completing delivery tasks.
-
Delivery List: Check the second tab in the depot nodes menu for available delivery jobs.

-
Daily Limits: You can complete 3 delivery jobs per day.
-
Rewards: Each successful job rewards you with 30 credits in addition to stock bills (Valley or Wooing). This adds another 90 credits to your daily total.
Maximizing Your Shop Strategy
Because you can earn well over 1,000 credits but can only keep 300 between days, your goal should be to “wash” your credits through the shop. Use your excess to buy out Arsenal Tickets first, then focus on Ouroberyl and tier-up materials. If the current shop selection is poor, use a small amount of credits to refresh the stock and find better value.
By staying consistent with friend ship visits and clue gifting, you can reliably fund your weapon pulls and rare material acquisitions without spending premium currency.
