Zenless Zone Zero Version 2.6 Unveils Limited Sunna & Yixuan Banners: A Comprehensive Guide

Version 2.6 of Zenless Zone Zero: Sunna, Yixuan, and Advanced W-Engines Redefine Gameplay

Zenless Zone Zero’s Version 2.6 introduces its most significant character and weapon acquisition period to date. This “Signal Search” event, active until March 4, 2026, at 11:59 AM (server time), presents an array of limited S-Rank Agents and sought-after W-Engines. Its strategic importance means both seasoned players and new recruits will find their roster development significantly impacted for the foreseeable future.

Headlining this update are the powerful S-Rank Agents, Sunna (a Physical Support) and Yixuan (an Auric Ink Rupture specialist). Each arrives with dedicated banners that are complemented by two potent W-Engine pools, each specifically designed to enhance their unique combat styles. A thorough grasp of these promotional offers and the associated event calendar is essential for players aiming to maximize their acquisitions and overall team strength.

Decoding Banner Operations: Odds, Pity Guarantees, and Acquisition Rules

Elevated Drop Chances: Promotional banners feature enhanced acquisition rates for their designated S-Rank and A-Rank Agents or W-Engines. Specific numerical probabilities have not been officially disclosed.
Pity Safeguard:
- Agent-Specific Banners (e.g., Sunna, Yixuan): The pity count is maintained and carries over between these exclusive Agent banners. This means your progress towards a guaranteed S-Rank Agent remains intact if you switch your pulls between Sunna’s and Yixuan’s offerings. This counter, however, functions separately from W-Engine banners.
- W-Engine Banners: A similar progressive pity system operates for the Dissonant Sonata and Vibrant Resonance W-Engine banners. This cumulative progress is distinct and does not transfer to Agent banners.
Event Exclusivity: As per official statements, the limited S-Rank Agents and W-Engines will not be incorporated into the standard “Star-Studded Cast Stable Channel” once the event concludes.

Is Summoning Worth It? (Advice for Free-to-Play & Budget-Conscious Players)

For Sunna: This agent offers specialized support capabilities for Physical damage compositions. She is strongly advised if your current roster lacks robust healing, defensive options, or synergistic support for Physical teams.
For Yixuan: Positioned as a premier Auric Ink Rupture damage dealer, Yixuan is a valuable acquisition if your team requires a dedicated Rupture main carry or if you intend to strengthen your Auric Ink lineups for future challenges.
Regarding W-Engines (Thoughtbop, Qingming Birdcage): These are most impactful when paired with their respective S-Rank Agents. Players on a tight budget or those just starting out should generally bypass these unless they possess an abundance of in-game currency, as their utility diminishes without the corresponding character.
On A-Rank Duplicates: While Corin and Billy serve as useful Physical characters in the early to mid-game, their long-term strategic value is typically less significant than that of the limited S-Rank offerings.
Key Preparation Steps:
- Accumulate sufficient in-game currency to align with pity thresholds (refer to the GenshinBuilds currency acquisition guide).
- Analyze potential team synergies, particularly if you are focusing on acquiring either an Agent or a W-Engine independently.
- Keep track of event schedules, as these exclusive units may not reappear for a considerable period.

Players prioritizing efficient resource allocation should consider saving their pulls for crucial S-Rank Agents or W-Engines that provide substantial enhancements to their main damage dealers or support characters.

Assembling Formations: Optimizing Teams with Sunna and Yixuan

Sunna: Foundation of Physical Support

Ideal Companions: Best utilized alongside primary Physical damage dealers such as Corin, Billy, or any forthcoming Physical characters.
Primary Function: Enhances Physical damage output and maintains crucial support abilities.
Example Composition: Sunna, combined with Corin, plus a flexible Agility or Control character.

Yixuan: The Auric Ink Rupture Powerhouse

Preferred Partners: Thrives with Rupture or Ink-aligned support characters, ideally those offering energy regeneration or shield-breaking capabilities.
Key Contribution: Delivers consistent and high Rupture damage; a significant improvement for Ink-focused teams.
Sample Setup: Yixuan, supported by characters of the same elemental alignment, supplemented by a hybrid sustain unit.

Optimal W-Engine Combinations

To achieve peak performance, it is recommended to pair Thoughtbop with Sunna, and Qingming Birdcage with Yixuan—both are specifically engineered as integral enhancements for their respective Agents.
Other Options: While Housekeeper and Starlight Engine Replica offer greater versatility, they are typically surpassed in effectiveness by the S-Rank W-Engines, assuming players manage to acquire the latter.

Event Activities and Incentives: The Audition Gauntlet

This event introduces special audition stages, allowing participants to test drive prominent Agents such as Sunna, Yixuan, Corin, and Billy. Successful completion of these stages for the first time will yield rewards. Players who have already completed any associated prior challenges can instantly redeem their rewards directly from the event hub.

Eligibility Criteria: Requires an Inter-Knot Level of 8 and completion of the Main Story Prologue – Intermission.
Operational Period: From the rollout of Version 2.6 until March 4, 2026, at 11:59 AM (server time).
Prize Details: While specific rewards haven’t been detailed in official announcements, common inclusions typically consist of in-game currency, materials for character enhancement, and exclusive temporary items.

Illustrative Information

Official promotional banners and event artwork clearly delineate the featured characters and the event timeline. To aid player planning, each banner graphic presents the S-Rank and A-Rank Agents or W-Engines, visually representing their roles against vibrant urban backdrops—offering a swift guide for strategizing pulls.
