Titled “Old Deep Water Dies by Rising Tide It is Denied,” this update introduces the Qingbo Stockade region, two high-impact Operators, and a fundamental shift in how you manage your industrial base on Talos-II. --- ## TL;DR - Key Points * **Tangtang (6-star Cryo Caster)** releases March 12 with massive AOE Cryo damage and enemy-pausing Ultimate * **Rossi (6-star Physical Guard)** joins March 29 as the only Arts Infliction-to-Vulnerability converter * **4 Weapon Banners** including Tangtang’s Brigand’s Calling and Rossi’s Crimson Wolf signatures * **Qingbo Stockade** unlocks with Cuprium Ore requiring new Hydro Mining Rigs powered by water flow * **1,000 free Oroberyl** available in mail immediately to celebrate the update * **20 free permits** total via dual 7-day sign-in events (10 for Tangtang, 10 for Rossi) * **Agony Mode** disables all healing Tacticals, prepare sustain Operators like Snowshine or Ember * **Sanity Discount windows** on March 22 and April 10 for reduced stamina costs * **New quality-of-life fix**: Operators now enter Protocol Spaces with max HP and Ultimate Energy --- ## New Operators: Meet Tangtang and Rossi Version 1.1 introduces two new 6-star Operators that bring unique tactical utility to your squad. ### Tangtang (6-star Cryo Caster) **Release Date: March 12** Tangtang is the Supreme Chief of the Qingbo Stockade. Known as a “one-girl team,” her kit focuses on massive AOE Cryo damage. **Signature Ability:** Her Ultimate, **“DA CHIEF SEES YOU!”**, uses an “Olden Stare” to pause the actions of all enemies in a wide area, including bosses, creating a perfect damage window for your squad. **Key Strengths:** * Wide-area Cryo application for freeze-lock strategies * Boss-interrupting Ultimate creates free DPS windows * Self-sufficient kit reduces dependency on support ### Rossi (6-star Physical Guard) **Release Date: March 29** Rossi is the leader of the Wulfgard pack. She brings a unique defensive-shredding mechanic that physical-focused teams have been waiting for. **Signature Mechanic:** Rossi is currently the only Operator capable of converting **“Arts Infliction” stacks into Vulnerability**, a powerful defense-shredding mechanic that makes her an essential multiplier for physical-focused teams. **Key Strengths:** * Exclusive Arts Infliction-to-Vulnerability conversion * Massive team damage amplification against bosses * Synergizes with Pogranichnik and Lifeng physical teams --- ## Arsenal Issue: Weapon Banners Version 1.1 features four distinct weapon banners optimized for signature synergies with both new and existing Operators. ### Phase 1 Weapon Banners (March 12) | Banner | Weapon | Type | Best For | | -------------------------- | ------------------- | --------------- | ------------------------------------------------------------------------------- | | **Budding Anew Issue** | Brigand’s Calling | Handcannon (6★) | Tangtang’s signature; enhances “Agility Atk Detonate” mechanics and SP recovery | | **Express Delivery Issue** | Delivery Guaranteed | Arts Unit (6★) | Gilberta’s signature; optimized for her support kit | | **Graffiti Issue** | Artzy Tyrannical | Handcannon (6★) | Yvonne’s signature; maximizes Heat damage and Melting Flame stacks | ### Phase 2 Weapon Banners (March 29) | Banner | Weapon | Type | Best For | | ----------------------- | ------------ | ---------- | ---------------------------------------------------------------------------------- | | **Scarlet Pearl Issue** | Crimson Wolf | Sword (6★) | Rossi’s signature; generates “Wolf” stacks on critical hits for damage and sustain | Industrialists will need to adapt their AIC factory layouts for the new Qingbo Ridge area. This region introduces **Cuprium Ore**, a resource vital for crafting advanced Version 1.1 gear sets. ### Hydro Mining Mechanics Unlike previous minerals, Cuprium requires the **Hydro Mining Rig**. These facilities harness water flow instead of electricity, meaning you must prioritize proximity to water sources rather than the electrical power grid. **New Infrastructure:** | Facility | Purpose | | ------------------------- | -------------------------------------------- | | **New Conduits** | Transport liquids across your factory layout | | **Water Treatment Units** | Process and filter water for industrial use | | **Hydro Mining Rigs** | Extract Cuprium Ore using water power | ### Strategic Considerations * Water proximity becomes the new limiting factor for resource extraction * Existing electrical grids may need rerouting to accommodate hydro-focused zones * Cuprium is required for endgame Version 1.1 gear crafting --- ## Version 1.1 Event Calendar & Rewards Stay on track with this timeline of limited-time activities and rewards: ### Phase 1: The Chief’s Arrival (March 12 – March 29) | Date | Event | Details | | --------- | --------------------------------- | -------------------------------------------------------------------------------------------------------------- | | **03.12** | “River’s Daughter” Headhunting | Tangtang’s featured banner begins | | **03.12** | “Gently Flows Qingbo” | 7-day sign-in event providing **10 Tangtang-phase recruitment permits** and T-Creds | | **03.12** | Tangtang Combat Drills | Trial stage to test Tangtang’s kit with pre-set gear; earn first-clear rewards | | **03.12** | “Quietly Flows the Spring” | Guide event introducing Qingbo Stockade; complete story missions for Oroberyl and resources | | **03.19** | Exploration Day | Supply event, submit daily items from Originium Science Park for account progression materials | | **03.22** | Sanity Discount | 3-day window with significantly reduced Sanity costs for challenge domains (limited to 3 uses/day) | | **03.26** | Umbral Monument \[Searing Scars\] | Permanent high-difficulty series featuring new enemies from Wuling | | **03.26** | Monumental Etching: Scorch Mark | Limited-time event tied to Umbral Monument, complete challenges for extra Oroberyl and Trimmed Engraved Medals | ### Phase 2: The Pack’s Pearl (March 29 – April 15) | Date | Event | Details | | --------- | ------------------------ | --------------------------------------------------------------------------------------------------- | | **03.29** | “Wolf Pearl” Headhunting | Rossi’s featured banner begins | | **03.29** | “Pearl of the Pack” | 7-day sign-in event providing **10 Rossi-phase recruitment permits** | | **03.29** | Rossi Combat Drills | Trial stage to master Rossi’s “Infliction-to-Vulnerability” conversion rotation | | **03.29** | “Grotto Survey” | Major update to Delver of the Cryptic, six Wuling-themed maps with Jet Drone vertical puzzles | | **03.29** | “Cleanse and Rinse” | Control spray drones to clean targets for rewards, including a special character portrait | | **04.09** | Survival Training | Bomb-based “tower defense” mode, use Industrial Explosives and strategic positioning to repel waves | | **04.10** | Sanity Discount | Second 3-day window of reduced stamina costs for endgame gear farming | --- ## Gameplay Updates & New Zones Version 1.1 expands the industrial endgame with new resources, zones, and permanent content. ### New Zones | Date | Update | Details | | --------- | ----------------------------------- | ----------------------------------------------------------------------------------------------------------------------- | | **03.12** | Etchspace Salvage (Aberrant Zone 4) | New high-level zone providing Basic Headhunting Permits and materials for upgrading factory storage systems | | **03.26** | Umbral Monument \[Searing Scars\] | Permanent high-difficulty combat series featuring new enemies from the Qingbo region | | **03.26** | Monumental Etching: Scorch Mark | Limited-time event tied to Umbral Monument, complete specific challenges for extra Oroberyl and Trimmed Engraved Medals | --- ## Pro-Tips for Endministrators ### Prep for Agony Mode The Umbral Monument update includes “Agony Mode,” which disables all healing Tacticals. Ensure you have a dedicated sustain Operator like **Snowshine** or **Ember** leveled up to keep your team alive without consumable healing. ### Optimize Your Gear Use the new **Valley Multi-Line Engraving Kit** to create Essences with three customized stats. This is the best way to reduce RNG friction when building: * **Tangtang**: Prioritize Agility for faster Ultimate cycling * **Rossi**: Prioritize Critical Rate for consistent Vulnerability application ### Claim Your Free Pulls 1. **Immediate**: Check mail for **1,000 Oroberyl** to celebrate the update 2. **Sign-in Events**: Claim **10 permits** from “Gently Flows Qingbo” (Tangtang phase) and **10 permits** from “Pearl of the Pack” (Rossi phase) **20 total** 3. **Etchspace Salvage**: Farm Basic Headhunting Permits in the new Aberrant Zone 4 ### Plan Your Sanity Spending Two **Sanity Discount windows** (March 22 and April 10) reduce stamina costs for challenge domains. Save your Protocol Pass Extractors and bank up to 1,200 Sanity before these dates to maximize farming efficiency. ### Combat Quality-of-Life Take advantage of the new fix: **Operators now enter Protocol Spaces with maximum HP and Ultimate Energy**. You no longer need to “farm” energy before a tough fight, jump straight into the challenge. ![Version 1.1 Event Calendar](https://endfieldhub.org/images/blog/version-1-1-calendar.webp) _Version 1.1 complete event calendar showing all Phase 1 and Phase 2 activities_ --- ## Summary Version 1.1: “Old Deep Water Dies by Rising Tide” represents Endfield’s first major expansion, delivering: * Two meta-defining 6-star Operators with unique mechanics * A new industrial paradigm centered on hydro-power * Weeks of limited-time events with substantial Oroberyl rewards * Permanent endgame content via Umbral Monument and Delver of the Cryptic updates The tide is rising on Talos-II.
