Arknights Endfield Support System Explained – How to Set Your Best Units for Others
Arknights Endfield’s support system lets you loan your best operators to friends while earning consistent Friend Point (FP) and resource rewards in return. Setting the right units here is free value for both you and your friend list.

How the Endfield Support System Works
The support feature unlocks once you clear early story content and gain access to Dijiang’s Guest Terminal, where you handle friends and production assists. From there, you can back up other players’ bases and lineups and receive FP when they use your assistance.
Unlike the original Arknights’ pure combat loan system, Endfield’s support is tightly tied to production and Dijiang cabin efficiency, so strong operators indirectly speed up long‑term account growth. This means your support picks should prioritize consistent uptime and base synergy over niche challenge units.
How to Add Friends and Unlock Support
You add friends from the Friends menu using either a player name or numeric UID, both found on each player’s profile screen. Once a request is accepted, the friend becomes eligible to receive your Production Assists and see your shared setups.
There is a hard cap on pending requests, so you must periodically clear or accept invitations to keep your support network growing. Since FP comes from helping active accounts, prioritize players who log in frequently and actually run production and combat content.
| Step | Action | Details |
|---|---|---|
| 1 | Open Friends menu | Accessible from the main pause/watch menu. |
| 2 | Search by UID or name | Enter exact ID to send a request. |
| 3 | Accept requests | Manage them in the Friend List tab. |
How to Access and Use Production Assists
To provide support, go to Dijiang, open the Guest Terminal, then select the Production Assists option. From this menu, you can choose which friends to assist and confirm the deployment of your operators to their cabins and production chains.
Triggering Production Assists is most efficient when you also check the Friend’s Price section, where Market‑Priced Items can be bought or sold while your support is active. This loop converts your strong account into a reusable economic engine that benefits both you and your friend.
How to Set Your Best Support Units
For Endfield’s combat‑oriented support, you want units that slot easily into meta team archetypes such as Cryo DPS cores, Electric amplifiers, or sustain pieces. Core carries like Last Rite or key enablers such as Xaihi, Perlica, and Ardelia naturally perform well when borrowed because they fit almost any relevant composition.
On the utility side, characters that boost SP, provide global buffs, or increase Vulnerable stacks (for example, Pogranichnik or Chen in their recommended lineups) make ideal supports for advanced players pushing harder maps. Always fully level, gear, and essence these operators, then keep them on your support slots so your list sees a clear, high‑impact roster every day.
Extra Tips for Maximizing FP and Value
Rotate at least one support slot around current events or new stages so friends always have something relevant to borrow for the latest content. Finally, keep your roster updated with properly crafted gear and essences so any borrowed operator performs at their theoretical peak, turning every assist into a strong showcase of your account.
