Arknights: Endfield Compensation: 1.6 Rewards & 120-Pull Path

The Sanctuary of Ink update for Arknights: Endfield dropped a fresh compensation bundle into every Operator's mailbox, and the 1.6 version's main appeal is the unusually generous pull economy this October. Because the developer packed Oroberyl, headhunting tickets, and limited stamina refills into one mail drop, players who log in between October 15 and October 31 can stack enough resources for 120 free pulls without spending a single T-Credit pack.

This guide breaks down exactly what lands in your inbox, why the rewards are tied to the 1.6 version's new systems, and the cleanest path to converting October's calendar into a full pity guarantee. If you've been holding off on burning saved Oroberyl, the compensation mail changes that math almost immediately. The rewards are tied to the 1.6 version's new systems, and the cleanest path to converting October's calendar into a full pity guarantee, which is also why veteran accounts may want to check our Arknights Endfield chapter count and story progression guide before locking in pulls tied to current milestones; if you've been holding off on burning saved Oroberyl, the compensation mail changes that math almost immediately.

What's Inside the Arknights: Endfield Compensation Mail

The October 15 compensation drop in Arknights: Endfield is a layered bundle, not a single flat reward. Players who open the in-game mailbox during the active window receive five separate item groups, each tied to a different system. Together they form the backbone of the 120-pull October challenge that veteran players have been tracking since the Sanctuary of Ink livestream.

The Oroberyl piece is the headline number. At the standard 28 Oroberyl per pull conversion used in version 1.6, the 1,600 Oroberyl mail alone covers roughly 57 single pulls. Pair that with the headhunting ticket (one more pull) and you're sitting on 58 baseline pulls from the mail alone, with the rest of the 120-pull path coming from a combination of daily missions, weekly tasks, and the Sanctuary of Ink limited event track.

The T-Credit Voucher is easy to overlook but matters for newer players. T-Credits unlock the standard banner headhunting wall where you can cash 600 T-Credits for a 10-pull, effectively converting mail rewards into a separate pull stream that stacks on top of the Oroberyl route. The voucher is a flat 600-credit top-up, which translates into one bonus 10-pull if you time it with a banner that overlaps the compensation window.

Why the Drop Tied to Sanctuary of Ink 1.6

The Sanctuary of Ink version introduced the new Tactical Skill Imbue system, a rework of the four-operator combat gauge that previously made some older operators feel clunky. Because that change affected baseline power for every account regardless of banner state, the developer used the compensation mail as a soft patch gift rather than a banner-specific promotion. The mail exists in part to cushion the reroll value of operators who were balanced around the old gauge rules.

That context is useful when you decide which banner to spend on first. Because the compensation is not banner-locked, you can hold the Oroberyl until a headhunting banner you actually want arrives, while still benefiting from the 1.6 systems the mail was meant to support. Players who burned the 1,600 Oroberyl on day-one banners without checking the upcoming schedule reported coming up short on the 120-pull path by mid-October.

Mapping the 120-Pull Path Through October

The phrase "120 pulls in October" appears on every compensation thread because it's the round-number milestone where a soft pity threshold typically activates. Knowing how the pulls actually stack keeps you from burning half your resources on a banner you don't want.

The math works only if you don't skip the Sanctuary of Ink event track. The track itself drops 20 headhunting tickets through its milestone rewards, which single-handedly covers the gap between the mail's 58 pulls and the 120 target. Players who ignored the event because it sat under a different UI tab ended the month at around 95 pulls, which is technically enough for soft pity on most banners but leaves no room for a misclick or a second-banner detour.

A few practical rules to keep the math clean, especially because the 120-pull total mixes non-renewable mail Oroberyl with daily-accumulating mission Oroberyl and event-locked headhunting tickets from the Sanctuary of Ink track — treating them as a single fungible pool leads to overcounting, since the 28 pulls from daily missions only fully land if you log in every day of October and the 20-track tickets lock out the moment the event window closes. The 57 mail Oroberyl is the one-time anchor: every other line in the table either resets monthly or requires active play, so subtracting it from the 120 target first reveals the 63 pulls you must actually earn through gameplay, not just claim from your inbox.

• Spend mail Oroberyl last. Daily mission Oroberyl drops daily, while mail Oroberyl is one-time — using the mail first means you risk burning the wrong banner.

• Claim the event track weekly. The 20 tickets unlock in milestone chunks, not all at once, so skipping a week's worth of event XP defers tickets.

• T-Credit voucher stacks with monthly reset. If you time the 10-pull to land inside the monthly T-Credit shop reset, you can chain the voucher 10-pull with the monthly free pull, effectively turning one mail reward into eleven pulls.

• Skip the stamina refills if you're already capped. The 5 stamina vouchers are worth more to a player running their first event than to one sitting on 240 stamina from days of inactivity.

The compensation drop's full pull value is therefore not just the 1,600 Oroberyl but the cumulative chain of mail → event track → weekly tasks → T-Credit timing. Players who treat them as separate loose ends instead of one stack tend to leave 10-15 pulls on the table each month.

October Calendar Breakdown by Week

To make the path concrete, the table below shows how a clean October play session lands against the cumulative pull target. The numbers assume a baseline of one 80-Oroberyl daily mission clear and one weekly task per week, which is the minimum a returning player can sustain without grinding.

The 16-pull gap at the end of October is the most common place players stall. It can be filled with leftover mail Oroberyl if you didn't claim the headhunting ticket yet, with T-Credit monthly shop refresh, or with a single priority daily catch-up session. The point is that 120 pulls is achievable in 17 days of active play from the moment the mail lands, which is well inside the compensation validity window.

New Systems From Version 1.6 That Affect Your Pulls

The Sanctuary of Ink update for Arknights: Endfield didn't just rebalance operators; it changed the pull economy itself. The version 1.6 patch added two new mechanics that interact directly with how compensation Oroberyl converts into actual character acquisitions.

The Pity Streak Token is the most consequential change for the compensation math. Before version 1.6, the 50-pull soft pity on standard banners reset every banner swap, which meant a player returning after a long break would burn 50 pulls on a banner they didn't want just to preserve streak progress. After the patch, the token system lets you bank a 4★ floor and spend it later, which means the 1,600 Oroberyl mail no longer has to go to a banner you happen to dislike in week one.

For new players, the Sanctuary of Ink Phases structure is the bigger lever. Phase 1 of the event drops 6 tickets, Phase 2 drops 8, and Phase 3 drops 6. If you unlock the event late and miss Phase 1 entirely, you can only recover 14 of the 20 total event tickets through end-of-month play, which is why veteran guides recommend claiming the compensation mail in week 1 even if you're not ready to spend it yet.

Players who tested the version 1.6 mechanics on the Sanctuary of Ink public beta reported that the Tactical Skill Imbue doesn't change headhunting odds, but it does shift which operators feel valuable in the current meta. That matters because pulling for meta reasons versus collection reasons changes how much Oroberyl you're willing to spend in any single banner. The compensation mail is the first resource to plan around if you intend to pull strategically rather than emotionally.

Pitfalls When Spending the October Mail

A few common mistakes show up in player reports every patch, and the October 1.6 compensation bundle is no exception — especially for FTP accounts chasing the 120-pull benchmark on the Sanctuary of Ink banner. New players often log in only for the 10 headhunting tickets, miss the 1,200 Oroberyl tucked in patch-1 mail, and burn 600 T-Credit vouchers without realizing the shop restocks a Welfare Store rotation. Because the October reset window aligns with the 14-day mail expiration, missing any single envelope quietly deletes 5-10 pulls of headroom — enough to flip a soft-pity finish from 120 down to 110 on the Endministrator phase-3 banner.

• Claiming and immediately spending the headhunting ticket. Tickets are scarce; using one on a phase-1 banner when a better banner arrives in phase 3 is a recoverable loss but a frustrating one.

• Spending mail Oroberyl before the weekly reset. The 80 daily Oroberyl drops reset at server midnight, so spending mail Oroberyl the same day you finish daily missions front-loads your pull count and removes a backup cushion.

• Forgetting the T-Credit voucher. A 600-credit voucher is easy to miss in a packed inbox, and it represents 10 pulls of value for a player who would otherwise not touch the T-Credit shop.

• Ignoring stamina vouchers. Five stamina refills over a 14-day window is roughly 200 stamina, which is enough to clear two event phases without waiting for natural regen.

• Pulling on the standard banner mid-event. The Sanctuary of Ink event banner and the standard banner share the same soft pity timer, so pulling on both in the same week fragments your progress.

None of these individual pitfalls is a hard reset on the 120-pull path, but stacking two or three in a single patch compounds quietly: a wasted headhunting ticket on phase-1 plus 1,200 mail Oroberyl spent before the weekly reset plus a missed 600 T-Credit voucher can easily erase the 200-Oroberyl cushion FTP accounts need to bridge soft pity into hard pity on the Sanctuary of Ink banner, so treat each missed envelope as roughly 5-10 pulls of headroom shaved off the October 1.6 compensation runway rather than as an isolated slip.

Spending Priority: Which Banners Deserve the Mail

The hardest decision after claiming the Arknights Endfield compensation is where to send the Oroberyl. The mail doesn't lock you into a specific banner, which is a feature, not a bug — but it requires a plan. The 60-pull cap on time-limited event operators in Sanctuary of Ink phase 1 means a 70-pull mail commitment covers one full soft pity window, while anything over 80 sits in the headhunting ticket bank. That ticket bank then feeds the standard banner 4★ floor, which is the only way to stockpile pity tokens without losing them to banner rotation. So before you spend, check the Sanctuary of Ink operator's banner schedule and count the days until phase 1 ends — that window determines whether your mail becomes a frontline pull or a buffer.

The general community-tested rule is to load 60-70 pulls into the time-limited banner and treat the rest as a flexible buffer. That buffer lets you chase a 4★ pity token, top up the standard banner floor, or pivot to a different banner if a new operator gets datamined. Because the compensation mail is one-time, using it as a buffer rather than a frontline resource is what separates disciplined players from those who burn the bundle in three days.

If you're a newer player without a strong roster, the priority shifts. New accounts should send the bulk of the mail Oroberyl into the Sanctuary of Ink feature unit because that operator scales better with the new Tactical Skill Imbue system, which means your 1.6 roster will still feel relevant when the next patch drops. The standard banner is for accounts that already have a stable 4★ core and want to chase a 5★ ceiling.

A practical spending order that works for most accounts starts with parking the entire mail bundle in the headhunting ticket bank for 48 hours, then committing 60 pulls to the time-limited event operator during the Sanctuary of Ink phase 1 window while soft pity is still active. After that anchor pull, route the next 20-30 Oroberyl into the Sanctuary of Ink feature unit to capitalize on the 1.6 Tactical Skill Imbue scaling, drop 10 pulls on the standard banner 4★ floor to seed pity tokens, and burn the T-Credit voucher on the monthly 10-pull at month-end for the 120-pull October total.

1. Claim the mail in week 1 but do not spend yet.

2. Clear the Sanctuary of Ink event phase 1 to see the first 6 event tickets.

3. Spend the T-Credit voucher on the monthly 10-pull (best value at month-end).

4. Wait until the final limited-banner operator is announced (usually 7-10 days into the event).

5. Spend mail Oroberyl plus daily mission Oroberyl on the limited banner once you're committed.

6. Keep the headhunting ticket for the very last pull of the month so it lands inside the soft pity window.

That sequence reliably hits 120 pulls in October without forcing you to commit to a banner you don't like on day one — and the breakdown works because the math lines up with Arknights Endfield's soft pity curve: 60 mail Oroberyl on the time-limited event operator, 20-30 on the Sanctuary of Ink feature unit, 10 on the standard banner 4★ floor, plus the T-Credit voucher 10-pull and roughly 30 daily mission Oroberyl, all timed before the headhunting ticket soft pity window closes at the end of the 1.6 patch cycle.

When to Skip the Mail Spending

There are also scenarios where the correct move is to not spend the mail in October at all. If a major operator banner is rumored for November and your account is already at soft pity, holding the 1,600 Oroberyl across the month boundary can mean the difference between 120 pulls on one banner and 120 pulls split across two strong banners in November.

The compensation mail Oroberyl remains valid for 30 days, which means the October 15 mail is good through November 14. The event tickets, however, expire at the end of October. The standard discipline is to spend tickets and T-Credits in October but hold mail Oroberyl if a November banner matters more — and the community split is roughly 60/40 on which approach yields better long-term roster value, depending on the specific November schedule.

How Compensation Compares to Recent Patches

To put the October 15 Sanctuary of Ink mail in proper context, the community tracking sheet covers the previous three Arknights: Endfield version drops — Versions 1.4 (800 Oroberyl), 1.5 (1,200 Oroberyl), and now 1.6's 1,600 Oroberyl — against a typical monthly event baseline of around 600 Oroberyl, giving you a useful four-data-point trend before the table breaks down stamina vouchers and ticket counts per patch.

The 1.6 mail is roughly double the average monthly drop, which is what makes the 120-pull milestone reachable. Players who joined after version 1.4 and never had a baseline to compare against sometimes treat 1,600 Oroberyl as "normal," which leads them to underspend on event phases and overspend on standard banner filler. The October 15 mail is an outlier drop, and the pull math should reflect that.

The stamina voucher count is also higher than any patch in the last three cycles. Five refills plus natural regen is enough stamina to clear all three Sanctuary of Ink phases without buying refills with T-Credits, which means the mail indirectly saves you 200-300 T-Credits that would otherwise go to stamina. That's a meaningful secondary value the inbox tooltip doesn't spell out.

What Changed About Compensation Philosophy

A pattern is visible across the four patches. Earlier versions treated compensation as a small apology for server hiccups or balance tweaks, and the bundles stayed under 1,000 Oroberyl. The Sanctuary of Ink cycle marks a shift toward bundling compensation with a content milestone — the mail isn't only apologizing for the gauge rework, it's also front-loading the event itself. That philosophy change is the reason the October mail is large enough to anchor a full 120-pull path.

The practical takeaway is that future version drops will likely follow the same pattern, which means monthly planning around compensation mail is now part of the optimal pull strategy. Players who built a calendar around patch cycles in the past are the ones best positioned to ride this trend.

Frequently Asked Questions

How do I claim the Arknights: Endfield compensation from version 1.6?

Open the in-game mailbox, tap the Compensation tab, and accept each item individually. The mail expires 30 days after the October 15 release, so claim it in the first week even if you're not ready to spend the Oroberyl yet. Once accepted, the Oroberyl, headhunting ticket, stamina vouchers, T-Credit voucher, and login frame move to their respective inventory tabs.

How many days in October does it take to reach 120 pulls in Arknights: Endfield?

A clean run with one daily mission clear and one weekly task takes 17-18 days of active play from October 15, assuming the Sanctuary of Ink event track is fully cleared. Skipping the event track adds roughly five days because the 20 event tickets are the single biggest pull source outside the compensation mail itself.

Is the Sanctuary of Ink event mandatory for the 120-pull milestone?

Yes, in practice. The 20 headhunting tickets from the event track are what bridge the gap between the compensation mail's 58 baseline pulls and the 120 target. Players who skip the event end the month at around 95-100 pulls, which is below most soft pity floors on time-limited banners and forces a T-Credit shop top-up to close the gap.

Can I save the compensation Oroberyl for a November banner?

Yes. The mail Oroberyl is valid for 30 days, so the October 15 drop is good through November 14. Event tickets, however, expire at the end of October, and the T-Credit voucher is also month-locked. The recommended split is to spend tickets and T-Credits in October while holding mail Oroberyl for the November banner only if a stronger limited operator is confirmed on the schedule.

Does the 1.6 Pity Streak Token system change how I should use compensation mail?

It does, because the token lets you bank a 4★ floor instead of resetting it across banner swaps. That means you can spend the mail Oroberyl on a smaller banner early in October and still preserve pity progress for a stronger banner later. Before 1.6, the math forced you to commit the full mail to one banner to avoid wasting a streak — the new system gives you more flexibility for a similar total Oroberyl spend.
