Arknights: Endfield August 2026 Events Calendar: Liino, Heat Rage and Best Oroberyl Spending Plan

Before you spend a single Oroberyl in August, buy your premium currency at the best rate. Topuplist sells discounted Origeometry packs, the Monthly Pass and value bundles for Hypergryph's hit strategy RPG on its dedicated Arknights: Endfield top-up page — fast processing, secure transaction channels and 24/7 support, so the pull budget you build below stretches further than it would in-game.

August 2026 is the most packed month on the Arknights: Endfield calendar since launch. Version 1.4 "Homecoming" enters Phase 2 on August 9 with the debut of Liino, the 6-star Electric Supporter, while the limited-time challenge Heat Rage! Mega Arena! runs until August 13, The Rooted Realm opens on August 9, and a wave of sign-in events, endgame stages and redeem codes keeps free currency flowing. This guide collects the complete August events calendar, every Oroberyl reward node, the exact gacha costs and pity rules you need to budget around, and a spending plan for every budget tier — so you always know where your pulls are going, and where they are not. All details below follow the official Version 1.4 announcements as compiled by the official Arknights: Endfield website and mainstream English wikis such as Game8's Arknights: Endfield wiki.

Arknights: Endfield August 2026 Events Calendar

Liino Banner — "Good Morning From Your Dawnstar" (Aug 9 – Aug 30)

The headline event of August is Liino's debut banner, which goes live on August 9, 2026 at 12:00 (server time) and runs until the end-of-version maintenance on August 30. North American and European servers start one day earlier, on August 8. Liino is a 6-star Electric Supporter who works from off-field: her Battle Skill opens Vocalist Stance, giving the whole squad a continuous ATK buff and AoE healing while periodically dealing Electric damage, and her Ultimate applies Electric and Nature amplification plus forced Electrification. The banner also features Arcane and Camille as off-rate limited 6-stars, with Ember, Lifeng, Ardelia, Last Rite and Pogranichnik filling out the pool. Liino's signature polearm Bedazzling Night Debut runs alongside her on the Bedazzled Issue Arsenal banner. If you are targeting Liino, remember the 120-pull hard guarantee does not carry over to the next banner — more on that below.

Heat Rage! Mega Arena! (Jul 30 – Aug 13)

Heat Rage! Mega Arena! is the signature challenge event of the month. Released on July 30, it runs until August 13 at 04:00 (server time) and asks you to clear eight stages with teams of no more than two Operators. The first three stages were available at launch; one new stage unlocks every day at 04:00 (server time). Each stage has a Normal and a significantly harder MAXED mode, and clearing Normal unlocks the higher difficulty. You need to have completed Chapter I Process II: Paving the Way to participate. Clearing the full gauntlet rewards 1,200 Oroberyl, the Portrait Frame: Heat Ragers' Party and a Mark of Perseverance. Bring your best duo — this event was designed to make you think hard about two-Operator synergy, and community discussions on Reddit and ResetEra highlight it as one of the patch's most skill-testing pieces of content.

The Rooted Realm (Aug 9 – Aug 30)

The Rooted Realm opens on August 9 at 12:00 (server time) and runs to the end of the version. Gather Aurylene Fragments across the map and complete Realm Quests to claim 1,600 Oroberyl and a Mark of Perseverance. It is a light, exploration-style event — a good excuse to revisit the new Wuling zones while you wait for Liino's banner to arrive.

Sign-In Campaigns and Login Rewards

August has two overlapping login events worth logging in for every single day:

• Bedazzling Dawnstar Sign-In (Aug 9 – Aug 30): sign in for 7 days to collect 5× Bedazzling Dawnstar HH Permits — free pulls for Liino's banner.

• Gaze North to the Rift Sign-In (until Aug 9): still claimable in the first week of August; it grants 5× Gaze North to the Rift HH Permits for Arcane's banner, which ends August 9.

• Tribute of Companionship (until Aug 9): the 3-day login event gives 3,000 Oroberyl, 5 Basic HH Permits and the 6-star sword Farsight — grab it before it expires.

Endgame Content: Monumental Etching, Umbral Monument and Delver of the Cryptic

The second half of August brings three endgame drops. Umbral Monument gains the Howlers of the Crag series (4 stages) on August 6, rewarding Marks of Perseverance, Advanced Cognitive Carriers, Arms INSP Sets and Protohedrons. Alongside it, the limited Monumental Etching: Beastly Howl (August 6 – August 20) hands out 1,200 Oroberyl and an Advanced Progression Selection Crate I. Then, on August 19, the Delver of the Cryptic mode adds the Artful Realm of Six Cardinals spatial set — three Protocol Spaces at launch and three more on August 26 — worth 1,200 Oroberyl and a Mark of Perseverance on completion.

Redeem Codes Still Active in August

Code redemption is quick free currency. As of early August 2026, the active codes are ENDFIELDGIFT (all platforms) and ENDFIELD4PC (PC only), plus a third code granting 150 Oroberyl, T-Creds and Combat Records. The Version 1.4 livestream code (Sticker: Safety Helmet + 71,600 T-Creds) is still redeemable until August 30. Redeem them in-game via Settings → Platform & Account → Exchange Code. Codes expire — redeem before maintenance, and do not forget the 1,800 Oroberyl maintenance compensation that arrived with the Version 1.4 update.

How Much Oroberyl Can You Earn in August 2026?

Adding up every confirmed event claimable during the August window — excluding daily/weekly tasks, exploration and Authority Level rewards — gives you roughly:

On top of that, the two sign-in events add 10 banner-specific HH Permits (5 for Arcane, 5 for Liino) — worth about 5,000 Oroberyl in pull value. In practice, expect roughly 12,000–15,000 Oroberyl-equivalent (25–30 pulls) during August before you touch daily tasks, the battle pass or your wallet. That is enough for one soft-pity 6-star attempt, but not enough for the 120-pull hard guarantee — plan accordingly.

Gacha Costs and Pity Rules to Budget Around

Pull Pricing

One pull costs 500 Oroberyl; a 10-pull costs 5,000 Oroberyl (about 66 Origeometry, roughly 20). Reaching the 120-pull hard guarantee costs **60,000 Oroberyl (about 792 Origeometry / ~300)**. The premium currency Origeometry converts to Oroberyl at 1:75, so every discounted pack you buy multiplies into more pulls.

The 80/120 Pity System

• Soft pity: you are guaranteed a 6-star by pull 80 (40,000 Oroberyl). From pull 65 onward, the 6-star rate climbs by 5% per pull. At 80 there is a 50/50 for the rate-up unit. This counter carries over between Chartered banners.

• Hard pity: the rate-up operator is guaranteed at pull 120 (60,000 Oroberyl). This guarantee does not carry over — it resets every banner and can only trigger once per banner.

• Milestones: 30 pulls on a Chartered banner refund a free 10-pull (Urgent Headhunting), and 60 pulls grant a Headhunting Dossier — a free 10-pull for the next banner. At 240 pulls you receive a bonus duplicate token (Potential) for the rate-up operator.

• Beginner banner: the New Horizons banner gives a 20% discount (4,000 Oroberyl per 10-pull) and guarantees a standard 6-star within 40 pulls, plus a 6-star weapon selector. Clear it early.

Weapon Banner Economics

The Arsenal Exchange runs on Arsenal Tickets, not Oroberyl. You earn tickets from character pulls (6-star = 2,000; 5-star = 200; 4-star = 20), the season pass and bundles. A 10-pull costs 1,980 tickets. Rates are 4% for 6-star weapons, with the rate-up at 25%; 40 pulls guarantee a 6-star weapon and 80 pulls guarantee the rate-up weapon. Converting Oroberyl into Arsenal Tickets is a poor exchange rate — only pull the weapon banner with tickets you earned from character pulls.

Best Oroberyl Spending Plan for Every Budget

F2P Players: The Strict Order

1. Clear the New Horizons beginner banner first — 40 pulls for a guaranteed 6-star and a weapon selector is the best value in the game.

1. Claim every August event and code — 12,000+ Oroberyl is close to a soft pity by itself.

1. Use your banner-specific permits before they expire — the 5 Gaze North to the Rift permits on Arcane's banner (ends Aug 9) if you want him; the 5 Bedazzling Dawnstar permits on Liino's banner after Aug 9.

1. Never chase the 120-pull guarantee without the full 60,000 Oroberyl — if you lose the 50/50 at 80, either commit to 120 or cut your losses; a wasted hard pity is the single worst way to spend free currency.

1. Do not convert Oroberyl into Arsenal Tickets. Save leftover Oroberyl for Version 1.5's banner (Si is estimated for August 30+).

Light Spenders: Where the Discounts Matter Most

If you spend a little, the most efficient purchases are the Monthly Pass and discounted Origeometry packs — the recurring pass smooths your monthly income while packs cover the gap between soft and hard pity. Pick one target per patch (Liino this month, or save for Si), budget for the full 120 pulls (~$300 or 792 Origeometry), and treat the weapon banner as off-limits unless you have earned tickets. To make each dollar go further, stock up through Topuplist's Arknights: Endfield top-up page, which prices packs below in-game rates with instant delivery and 24/7 support.

High-Investment Players: Dupes, Weapons and the 240-Pull Token

For whales, the order of operations is: character first (120 guarantee) → dupe token at 240 pulls → signature weapon via Arsenal. Liino's Potential tokens at 240 pulls are cheaper than in most gachas, and her kit benefits from early dupe levels. Because the 240-pull milestone pays out a free token, deep spenders should commit fully to one banner rather than splitting across both. When you need a large batch of Origeometry at once, the All-In-One Bundle on Topuplist is the biggest discount package for Arknights: Endfield.

Headhunting Permit Priority

Regardless of budget, spend permits in this order: (1) banner-specific sign-in permits (they expire with their banner), (2) the free 10-pull milestones at 30 and 60 pulls, (3) Basic HH Permits on the standard banner if you are chasing a specific standard 6-star or just want pity progress, and (4) Oroberyl last — after you know exactly which banner you are committing to.

Should You Pull Liino or Save for Version 1.5?

Liino is a genuinely flexible unit — a healer, team-wide ATK buffer and anomaly enabler in one slot, which makes her excellent in Electric and Nature reaction teams and a strong long-term account pick. If you run Zhuang Fangyi, Perlica or any anomaly-focused team, she is a high-priority pull. If your roster is physical-focused or you are eyeing Si, the Feranmut Proxy revealed during the 1.4 livestream (estimated for August 30 / Version 1.5), it is completely reasonable to collect August's free currency and save.

Final August 2026 Plan

• Before Aug 9: finish Heat Rage (ends Aug 13), claim Tribute of Companionship, Gaze Towards the Northern Exclusion and the Arcane sign-in before they expire; redeem all active codes.

• On Aug 9: collect the 1,800 maintenance compensation, start the Bedazzling Dawnstar sign-in, enter The Rooted Realm.

• Mid-August: clear Monumental Etching: Beastly Howl (ends Aug 20); pull Liino with sign-in permits and budgeted Oroberyl.

• Aug 19+: clear Artful Realm of Six Cardinals stages as they unlock.

• Before Aug 30: finish Liino's banner decision, spend or save, and stock your Origeometry while Topuplist's discounted Arknights: Endfield top-up page prices hold.

FAQ

When does Liino's banner run in August 2026?

Liino's banner, Good Morning From Your Dawnstar, runs August 9 – August 30 on the Asia server (August 8–29 on NA/EU servers).

What rewards does Heat Rage! Mega Arena! give?

Clearing its 8 stages (2-Operator teams, Normal + MAXED modes) rewards 1,200 Oroberyl, the Portrait Frame: Heat Ragers' Party and a Mark of Perseverance. Participation requires completing Chapter I Process II.

How much Oroberyl can I earn for free in August 2026?

About 12,000–15,000 Oroberyl-equivalent (25–30 pulls) including sign-in HH Permits, before daily tasks, battle pass and exploration rewards.

How many pulls do I need to guarantee Liino?

120 pulls (60,000 Oroberyl). Soft pity guarantees a 6-star at 80 pulls (50/50 for Liino), and hard pity guarantees her at 120.

Does the 120-pull pity carry over to the next banner?

No. The 80-pull soft pity carries over between Chartered banners, but the 120-pull rate-up guarantee resets and can only trigger once per banner.

Should I spend Oroberyl on the weapon banner?

Only with Arsenal Tickets earned from character pulls. An 80-pull commitment (1,980 tickets per 10-pull) guarantees the rate-up weapon; converting Oroberyl into tickets is a bad exchange rate.

Where can I buy Origeometry at a discount?

On Topuplist — see the Arknights: Endfield top-up page for discounted Origeometry packs, the Monthly Pass and bundles with fast, secure delivery.
