Arknights: Endfield Patch 1.5 Rundown

Arknights: Endfield 1.5, Dreamscape of Wind and Snow, replaces 1.4 on 2 September 2026. It arrives in two halves three weeks apart: Typhoeus and the Snowy Forest on day one, then Suiming, the free 5★ Purrchena and the Yvonne rerun on 24 September. This is what changes, what it costs you in pulls, and what to do first.

Quick answer

---

The two halves of 1.5, and what opens when

The version does not land all at once. Phase 1 carries the new operator and the story map; Phase 2, three weeks later, carries the free operator and the puzzle city.

Maintenance starts at 06:00 (UTC+8) on 2 September. Everyone gets 1,000 Oroberyl, 10,000 T-Creds, 8 Elementary Cognitive Carriers and 4 Arms INSP Sets in the mail for it — claim them before you plan any pulls, because a thousand Oroberyl is real pull budget.

Typhoeus: what she actually does

Typhoeus is a 6★ Nature Striker who fights with an Arts Unit, and the short version is that she is an aerial damage dealer who wants to stay off the ground.

Her loop is built on a resource called Signs:

1. Enter Hovering with her Battle Skill It performs 5 aerial basic attacks, and each hit gives her 1 Sign.
2. Bank 8 Signs That is the trigger for her Combo Skill.
3. Spend them on the Combo Skill It lays down area Nature damage over time that slows enemies and raises the Nature Burst damage they take.
4. Open with the Ultimate on packs It grants extra hovering attacks that can trigger Hail of Arrows for area damage.

The slow and the Nature Burst amplification are the part that matters for team building: her Combo Skill is a debuff window, so she pairs with whoever else on your roster deals Nature damage rather than being a solo carry.

Purrchena is free, and so is her weapon

The 5★ Physical Defender Purrchena does not go on a banner. She is the reward for the Purry Big Feline! RAWR! giveaway event that opens 24 September, and she comes with the 5★ sword Dessert Moment, which raises Strength and Treatment Efficiency.

• free no pulls involved at all
• grind six missions for the full set

Clearing all six event missions gives enough copies to max the potential on both the operator and the weapon, so there is no reason to stop at the first clear. Budget an evening for it in the last week of September.

What 1.5 costs you in pulls

The thresholds have not moved, and they are the numbers to plan against:

Two rules decide whether saving is worth it. The 120-pull guarantee resets when a banner ends — it never rolls into the next one. The 80-pull counter does roll over, but only to another banner of the same type, and it still leaves you on the coin flip.

If you want both, the safe reading is to treat them as two separate budgets: 120 for Typhoeus in Phase 1, and a fresh count for Yvonne in Phase 2.

Snowy Forest and Suiming are not the same kind of map

Both are exploration areas and they play nothing alike.

Snowy Forest, outside Yinglung Pass, is the story map and opens with the version. Its gimmick is enchanted fog that walks you in circles, and it is built on Sami legend — the same well the soundtrack draws from, with Finnish musician Vilma Jää blending Nordic folk into the electronic and JRPG mix. Its regional boss is Gloomwald's Rage.

Suiming, on 24 September, is an entire city built as one puzzle. It runs on a 15-minute time loop:

• The city resets every 15 minutes, and rising and falling tides open routes that were closed a moment ago.
• You gather parts to repair the Waking Bell, which is the thread the whole map hangs on.
• Items you pick up persist across resets, so a loop that ends badly is not a wasted loop.

That last point is the one to internalise before you start. The loop is a timer on movement, not on progress — treat each 15 minutes as a scouting run and keep what you find.

Quality-of-life changes worth knowing

Most of this batch is small and lands where the game was tedious:

• Progression Overview — one screen listing what each operator still needs, instead of opening every character.
• Continuous AIC placement in wilderness mode, so a row of units is one action rather than one action each.
• Blueprint creation shows exact facility counts before you commit the build.
• Echoes of War lets you switch stages directly and shows your clear times on the result screen.
• Hideable button prompts during autoplay dialogue, plus a hide-UI option — for screenshots and for cutscenes.
• Gifting keeps working past max trust, and the engraved medal display scrolls by category.
• One-click Clue Quick Action in the Reception Room.
• New personal device types in the Talosite store.

A gear-set loadout feature for swapping whole gear configurations was described as planned rather than shipping here — do not expect it on 2 September.

What to do on patch day

1. Claim the maintenance mail 1,000 Oroberyl, 10,000 T-Creds, 8 Elementary Cognitive Carriers, 4 Arms INSP Sets.
2. Decide your pull budget before you open Winter Hunt 120 for a guaranteed Typhoeus; anything less is a coin flip at 80.
3. Push the main quest into the Snowy Forest The map is gated behind the story, and Gloomwald's Rage is the payoff.
4. Start the Virtuality season of Echoes of War It opens the same day; the Illusion season follows on 24 September.
5. Put 24 September in your calendar Free Purrchena, Suiming, and the Yvonne rerun all land together.
