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

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
- Immediate: Check mail for 1,000 Oroberyl to celebrate the update
- Sign-in Events: Claim 10 permits from “Gently Flows Qingbo” (Tangtang phase) and 10 permits from “Pearl of the Pack” (Rossi phase)—20 total
- 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.
