Recent transmissions from the New Eridu testing environment have provided a glimpse into the upcoming signal search rotations for Zenless Zone Zero. As Version 2.7 nears its conclusion, the community focus has shifted toward the leaked roster for Version 2.8 and the high-level roadmap leading into the massive 3.0 expansion. These leaks, originating from reliable data-mined assets and closed beta adjustment logs, suggest a significant shift in the elemental meta and the introduction of highly anticipated agents from the Outer Rim and Section 6.

Current Banner Context: The End of Version 2.7

As of mid-April 2026, the second phase of Version 2.7 is currently active, featuring the rerun of specialized agents that define the current "Shatter" and "Ether" compositions. Historically, the final banner of a cycle serves as a strategic bridge, allowing players to either consolidate their current teams or save resources for the power creep often associated with upcoming version milestones. Rumors suggest that the current drop rates for A-rank supports in the standard channel are seeing subtle adjustments behind the scenes, potentially preparing for a new synergy mechanic.

Version 2.8 Leak: The Arrival of Mistral and the Return of Yixuan

The most prominent information regarding the Version 2.8 banner involves the debut of a new S-Rank Agent, tentatively named Mistral. According to leaked kit descriptions, Mistral is expected to be a Physical Attack agent belonging to the specialized reconnaissance unit of the Obsidian Guard.

Mistral’s Potential Kit and Mechanics

Unlike traditional Physical agents who rely on raw impact, Mistral’s leaked abilities focus on "Precision Shred." The data indicates a unique mechanic where her Basic Attacks apply a stackable debuff that lowers the target's Physical Resistance specifically for Chain Attacks.

  • Ex Special Attack: A multi-stage dash that grants invulnerability frames while dealing massive Daze damage.
  • Ultimate: A wide-area execution move that resets the cooldown of the squad's support abilities if it triggers a finish.

Accompanying Mistral in the first half of Version 2.8 is rumored to be a rerun of Yixuan. Since her debut in the late 2.0 cycles, Yixuan has remained a staple for players utilizing the "Ink Rupture" attribute. Her presence on the banner is likely a strategic move by the developers to allow newer players to build a competent Anomaly-focused team before the difficulty spike predicted for Version 3.0.

The Second Half of 2.8: A-Rank Support Shifts

Leaked banner art for the second phase of 2.8 points toward a heavy focus on the Electric and Fire attributes. While a new S-Rank is not explicitly confirmed for the second half, early files mention a "Shadow Banner" system. This could mean a dual-rerun featuring Astra Yao and potentially Seed, the artillery specialist from the Obol Squad.

For players who missed Seed during the 2.2 cycle, this leak is particularly vital. Seed’s first-person firing mode remains a unique gameplay mechanic in New Eridu, and her synergy with current Fire-attribute agents like Orphie has only improved with the introduction of new Drive Discs in recent patches.

Version 3.0 Expansion: The "Void Crystal" Meta

Looking further ahead, the most ambitious leaks involve the 3.0 expansion. Internal project codenames suggest the introduction of a seventh element or a "Sub-Attribute" system called Void Crystal. This would fundamentally change how Discord (the elemental reaction) is calculated.

Speculated banners for 3.0 include:

  1. The Hollow Overlord (S-Rank): A central figure in the upcoming storyline, rumored to be the first agent capable of switching elemental stances during combat.
  2. Section 6 Leader Rerun: After a long absence from the rotation, the leader of Section 6 is expected to return with a specialized W-Engine that complements the new Void mechanics.

W-Engine and Bangboo Banner Leaks

The weapon channel is also seeing significant leaks. For Version 2.8, the signature W-Engine for Mistral, tentatively titled "Obsidian Edge," is rumored to feature a base stat of 48% Crit Damage at level 60. Its passive ability is leaked to increase the wearer's Energy Generation Rate by 0.5% for every point of Daze inflicted on the enemy, up to a maximum of 25%.

Regarding Bangboos, the leaked "Rocketboo Prototype" is generating buzz in the theory-crafting community. This S-Rank Bangboo supposedly provides a specialized buff to agents who utilize "Follow-up Attacks" (FuA). If the leaks hold true, this Bangboo will be essential for maximizing the output of the Orphie-Seed fire core, which has dominated the Shiyu Defense leaderboards recently.

Meta Analysis: Should You Pull or Save?

Based on the current leak landscape, the decision to pull in Version 2.8 depends heavily on your roster's elemental coverage.

  • For Physical Main DPS Seekers: If you lack a high-tier Physical attacker, Mistral appears to be a robust investment. Her leaked resistance-shredding capabilities suggest she will be future-proofed against high-defense bosses in the upcoming Hollow Zero updates.
  • For Anomaly Enthusiasts: The Yixuan rerun is the priority. Despite being several versions old, her "Ink Rupture" application speed has yet to be matched by newer units.
  • The Case for Saving: For F2P (Free-to-Play) proxies, skipping 2.8 entirely might be the most rational choice. The leap from 2.x to 3.0 historically involves a significant power shift. Saving Polychromes for the 3.0 anniversary banners—which usually offer high-value "buy-one-get-one" or increased S-Rank drop rates—could provide better long-term account value.

Reliability of These Leaks

It is important to remember that all data-mined information is subject to change. The developers have been known to swap banner orders or adjust kit numbers as late as the pre-download phase. For instance, the previously leaked "Ice Support" agent for 2.7 was pushed back to an unknown date, replaced by the current rerun cycle.

Proxies should treat these leaks as a planning tool rather than absolute certainty. The official livestream for Version 2.8, expected to air in early May, will provide the final confirmation on these rosters and the official skill names.

Closing the Loop on New Eridu's Future

The trajectory of Zenless Zone Zero banners suggests a move toward more complex, multi-layered team synergies. Whether it is the precision of Mistral or the elemental chaos of the rumored 3.0 Void agents, the next few months will be transformative for the game's meta. Monitoring the signal search leaks allows players to manage their Polychromes effectively, ensuring they are prepared for the challenges within the next layer of the Hollows.
