If an Endfield account has been inactive, opening the top-up page should not be the first move. Check the live Event Center for Protocol Reconnection, confirm that the account qualifies, claim the available return rewards, and only then calculate the Homecoming gap. The return route may reduce the amount of Oroberyl or permits still needed; it does not guarantee Arcane, Liino, or any fixed pull result.
The Return Route Has Two Separate Checks
The official Homecoming Version Update Notes confirm that Protocol Reconnection received participation optimizations. They also separately list the Homecoming mail compensation: 900 Oroberyl for update and 900 Oroberyl for bug-fix compensation, with pre-update character creation as the stated eligibility condition. That distinction matters because the return event and the compensation mail are not one shared reward bucket.
The current public Protocol Reconnection reference lists these account gates. These conditions are a public mechanism reference, not a complete official Homecoming eligibility table; if the live Event Center uses different wording, the in-game account screen overrides the reference:
| Check | What the public reference says | What the player must verify |
|---|---|---|
| Authority | Authority Level 3 or higher | The target account’s current Authority Level |
| Story progress | Chapter I Process I: Valley Reboot completed | The mission state in the account, not a remembered milestone |
| Inactivity | At least 21 consecutive days without logging in | The actual last-login boundary shown or implied by the live event |
| Previous participation | At least 42 days since the prior Protocol Reconnection event | Whether the account already activated a recent return event |
| Claim window | A personal window ending after the activation period | The exact expiry time displayed in the Event Center |
These are useful audit fields, not a substitute for the live account screen. The wiki is a stable public mechanism reference, not an official guarantee of the reward state on every server or account.
Claim the Return Event Before Counting the Gap
Protocol Reconnection is described in the public reference as a permanent return event with a limited personal activation window. Its reference separates a seven-day Reconnection Sign-In from Reconnection Tasks, where returning players complete progression actions and collect milestone rewards. A community event guide also reports a current Homecoming return stack including Oroberyl, permits, and materials, but those amounts are only a community signal until the account’s Event Center shows them.
Use this claim ledger:
| Reward state | Count it toward Arcane or Liino? | Next action |
|---|---|---|
| Event not visible | No | Check story, Authority, server, and inactivity gates |
| Event visible but eligibility unclear | No | Wait for the account screen to resolve the gate |
| Eligible, reward unclaimed | No | Claim it before doing pull math |
| Claimed and balance updated | Yes | Record currency and permit type separately |
| Reward shown in a community guide only | No | Use it as a question for the live Event Center, not as balance |
Do not add a promised return reward to the budget because a fan page or invite post lists it. A resource becomes usable for the calculation only when it is on the correct account and accepted by the intended banner.
Keep the Return Event Separate From the 900+900 Mail
E01 already handles the Homecoming compensation route. Its official boundaries are specific: the character must have been created before the update, the two 900 Oroberyl rewards arrive by in-game mail, and the mail has a version-maintenance expiry. C07 should not relabel that compensation as a returning-player reward.
After returning, make three separate entries:
Protocol Reconnection: only rewards actually claimed from the return event.Homecoming compensation: the two separate 900 Oroberyl mails, if the account is eligible and the mail is visible.Other Homecoming events: login, scratch, guide, or exploration rewards that have already been claimed.
Then choose one target sentence: “The target is Arcane,” “The target is Liino,” or “The target is not clear yet.” Do not combine both operators into one unlimited budget. The Homecoming pull-budget guide covers this received-resource and stop-point calculation; C07’s job is to make sure the free return lane is checked first.
When Top-Up Becomes the Next Step
Top up only after four conditions are true:
- the Event Center confirms the account’s return eligibility or confirms that no return reward is available;
- all currently claimable free rewards are collected or deliberately excluded;
- the active Arcane or Liino banner, permit type, and qualifying counter are visible;
- the remaining Oroberyl-funded gap fits the spending cap set before pulling.
If the event is unavailable because the account misses the inactivity gate, that is not a failed purchase. It simply means the return route cannot be counted for this account. If the event expires before the rewards are claimed, remove them from the budget and recalculate. If the target is still undecided, hold rather than converting uncertainty into a top-up.
Once a real gap remains, review the Arknights: Endfield top-up page. The current product page lists Mobile and PC, International Server, login method, Game Account, Password, User ID, login server, and a selected bundle screenshot as order fields. Verify those requirements and the current route terms before sharing any account information or verification code. The page is a funding route, not proof of reward eligibility, banner guarantee, current price, stock, or delivery outcome.
Checked on July 18, 2026: official Homecoming update notes, the public Protocol Reconnection mechanism reference, the public Protocol Invitation community signal, U7BUY’s current Endfield top-up page, and the existing E01 pull-budget article. Because official public notes do not publish the complete returning-reward table, exact reward amounts in community references remain conditional and must be confirmed in-game.
FAQs
1. Should a returning Endfield player claim Protocol Reconnection before topping up?
Yes, if the account qualifies. Confirm the live eligibility gate, claim window, reward screen, and banner acceptance before counting the resource.
2. Is Protocol Reconnection the same as the 900 Oroberyl Homecoming compensation?
No. Protocol Reconnection is a return-event route. The 900 Oroberyl update and 900 Oroberyl bug-fix rewards are separate Homecoming mail compensation with their own eligibility.
3. Can a community reward table be used as guaranteed pull balance?
No. It can identify what to look for, but only rewards visible and claimed on the target account should enter the pull worksheet.
4. When should a returning player skip the top-up?
Skip or wait when the return event is not visible, the personal deadline is unclear, the target banner is undecided, the counter is unverified, or the remaining gap exceeds the preset cash cap.
