Arknights: Endfield Version 1.5, Dreamscape of Wind and Snow, launches on September 2, 2026. The update introduces the new 6-star Operator Typhoeus, along with the Snowy Forest area, new main story content, and challenge events. Phase 2 begins on September 24, featuring Yvonne's first rerun through a RE-Factor banner. Players can also obtain the 5-star Operator Purrchena and her signature weapon, Dessert Moment, for free.
This update introduces the new RE-Factor Headhunting system. It uses a separate pity system, and some pull progress carries over to later banners of the same type.
If you are saving Oroberyl for Typhoeus or Yvonne, check the banner schedules and pity rules for both phases in advance so you do not miss your target Operator. If you need more resources, you can also visit GamsGo to top up Arknights: Endfield Oroberyl and stock up before the new banners arrive.

Version 1.5 Banner Schedule
Arknights: Endfield Version 1.5 is divided into two phases. Its banners include one standard Chartered Headhunting banner and one new RE-Factor Headhunting banner. Typhoeus is the only new 6-star Operator in this update, while Yvonne returns through the new banner format.
Phase 1: Typhoeus Banner
Typhoeus's Winter Hunt banner opens after the Version 1.5 update and runs until September 30, 2026, at 12:00 (UTC+8). In addition to Typhoeus, Arcane, and Liino, the banner includes standard 6-star Operators such as Ember, Lifeng, Ardelia, Last Rite, and Pogranichnik.
Typhoeus is the only new 6-star Operator in Version 1.5. If your Nature team already includes Arcane or Liino, she can add ranged damage and strengthen Nature Infliction-based gameplay.
Phase 2: Yvonne Rerun Banner
Yvonne returns on September 24 through Resplendent Spectrum RE-Factor Headhunting #1 rerun. This is not a standard Chartered Headhunting banner, so it has separate pity progress and reward rules.
All obtainable 6-star Operators on this banner other than Yvonne are standard Operators. This is the first RE-Factor Headhunting banner rather than a standard rerun banner. If you already own Yvonne, you can obtain additional Tokens through pulls or milestone rewards to raise her Potential.
Version 1.5 Weapon Banners
Phase 1 features Deep Cold Issue, with Typhoeus's signature 6-star weapon as the Rate-Up weapon: Umbra of Frigid Eventide.
Phase 2 features Tag Artist Issue RE-Factor Issue #1, with Yvonne's 6-star Handcannon as the Rate-Up weapon: Artzy Tyrannical.
New Characters in Version 1.5
Weapon | Rarity | Type |
|---|---|---|
 Umbra of Frigid Eventide | ⭐⭐⭐⭐⭐⭐ | Arts Unit |
 Dessert Moment | ⭐⭐⭐⭐⭐ | Sword |
 Artzy Tyrannical | ⭐⭐⭐⭐⭐⭐ | Arts Unit |
Typhoeus
Typhoeus is a new 6-star Nature Striker introduced in Phase 1 of Version 1.5. Hailing from Rhodes Island, she is deeply interested in Sami legends and forgotten stories, and travels to the Snowy Forest beyond Yinglung Pass for this mission. Although she uses a large bow in her combat animations, her actual weapon type is Arts Unit. She can attack multiple enemies from the air and use Barrage Array to restrict their movement while dealing concentrated Nature damage.
Typhoeus's damage works with Nature Infliction. Players planning to build her can prepare Nature teammates, upgrade materials, and suitable gear in advance.
Purrchena
Purrchena is a 5-star Physical Defender who arrives in Phase 2 of Version 1.5 and uses a Sword. She does not need to be pulled from a banner, as players can obtain her for free from the Purry Big Feline! RAWR! event.
Complete the event missions to receive:
- 5-star Operator Purrchena
- Recommended weapon Dessert Moment
- Purrchena Potential materials
- Dessert Moment Refinement materials
- Other event rewards
By completing the event, players can obtain enough Operator and weapon copies to raise Purrchena's Potential and Dessert Moment's Refinement to the highest levels available from the event.
Purrchena provides protection, interruption resistance, healing, and Nature Infliction while making enemies take additional Arts damage. She is a valuable free Operator for players who need a Defender or a sustain option for a Nature team.
Free Pull Resources in Version 1.5
Version 1.5 includes login events, area exploration, character events, and limited-time modes. The confirmed sources of free rewards are listed below:
Reward Source | Start Date | Main Rewards |
|---|---|---|
| Fletched Irontip Sign-In | September 2 | Typhoeus banner recruitment permits |
| Snow Over Deep Woods | September 2 | Snowy Forest exploration rewards |
| Trial of the Bow | Phase 1 | Event mission rewards |
| Echoing Bell of an Old City | September 24 | Suiming exploration rewards |
| Purry Big Feline! RAWR! | Phase 2 | Purrchena, Dessert Moment, and Potential materials |
| Ridgeline Flows of Autumn | Phase 2 | Login rewards |
| New Echoes of War Season | During the version | Oroberyl and upgrade materials |
Because the reward amounts for some events still require confirmation from in-game notices, this guide does not yet calculate the total number of free pulls in Version 1.5. After launch, each event's Oroberyl, recruitment permits, and mission rewards should be added carefully to avoid double-counting exchange shop resources or limited-time permits.
Version 1.5 Pull and Pity Systems
Typhoeus Banner Pulls and Pity
Typhoeus uses the standard Chartered Headhunting rules. Existing eligible pity progress that has not yet triggered will be handled according to the game's current rules. If Typhoeus is your main target, prepare enough resources for the worst-case outcome instead of relying on average pull estimates. Her banner lasts until September 30, so you do not need to finish all your pulls before Yvonne's banner opens on September 24.
If you are still waiting for Si, you may want to save your resources. Si is not included in the confirmed Version 1.5 banner lineup.
RE-Factor Banner Pulls and Pity
RE-Factor Headhunting accepts Chartered HH Permits or Oroberyl. Its main rules are:
- At least one 5-star or higher Operator every 10 pulls
- A 6-star Operator within 80 pulls
- If no 6-star is obtained, the 80-pull pity progress carries over to other RE-Factor banners
- The 80-pull counter resets after obtaining any 6-star
- One free 10-pull at 30, 60, and 90 cumulative pulls
- The current Rate-Up 6-star is guaranteed within the first 120 cumulative pulls
- One Token for the current Rate-Up 6-star Operator for every 240 cumulative pulls
Note that the free 10-pull Urgent Recruitment rewards granted at 30, 60, and 90 pulls do not count toward pity or the pull totals required for cumulative rewards.
The 80-pull pity, 120-pull Rate-Up guarantee, and 240-pull Token reward are calculated separately. Only eligible progress within the same RE-Factor series can carry over; it cannot be shared with standard Chartered Headhunting.
New Gear in Version 1.5
New Version 1.5 Gear Set | Version 1.5 Gear Updates |
|---|---|
 Deep Bulwark |  Tidal Surge, Eternal Xiranite, and AIC Fieldwork |
Version 1.5 introduces the new gear set Deep Bulwark. In addition, the upcoming update adds new gear pieces to Tidal Surge, Eternal Xiranite, and AIC Fieldwork gear sets.
Version 1.5 continues to adjust the gear system around new character builds. Players preparing to build Typhoeus should prioritize her signature weapon, Nature damage, and gear that supports her Nature Infliction rotation.
Version 1.5 Maps, Missions, and Events
New Maps and Missions
Phase 1 opens the new Snowy Forestarea. Located beyond Yinglung Pass, it is the main setting for Typhoeus's story.
The Endministrator and Chief Engineer Andre enter the Snowy Forest to investigate an unusual signal, where they encounter Typhoeus. A strange mist covers the forest and may cause anyone entering it to loop back to the same place. As players explore, snow gradually accumulates on the characters' clothing and hair.
The area features new puzzles, enemies, and the boss Gloomwald Rage.

Version 1.5 also adds Typhoeus's Operator Mission, expanding on her story in the Snowy Forest.
Phase 2 opens Suimingon September 24. It is an explorable city built around a time-loop mechanic.
The city's tides cycle every 15 minutes. As the water level changes, some routes close while previously inaccessible areas may open. Players must collect parts needed to repair the Waking Bell during each cycle and find a route forward before the Blight Tide arrives.
A time reset does not erase all progress. Important parts already collected are retained, allowing players to use information and items from previous cycles to solve the puzzles gradually.

How Many Pulls Are Needed to Get Typhoeus in Version 1.5?
