Zenless Zone Zero 2026 Signal Search Guide: Sigrid, Knight's Extolment, and Rescreening

The 2026 Signal Search cycle in Zenless Zone Zero arrives with a packed schedule for Proxies, pairing a new limited Ice Attack Agent with a themed Attack W-Engine and a set of rescreening banners that reward careful planning. Running from 2026/08/19 12:00 to 2026/09/08 14:59 server time, the event window gives players roughly three weeks to decide where their Encrypted Master Tapes should go. What makes this period especially notable is not just the debut of Sigrid, but the return of several high-value Agents and W-Engines through separate channels with their own guarantee rules. The result is a banner lineup that asks a familiar question: should Proxies chase the new headline act, fill a missing role from the rescreening pool, or invest in a signature W-Engine?

"'Till the Ends of the Sky" and the Sigrid Debut

The headline Exclusive Channel, "'Till the Ends of the Sky," introduces the limited S-Rank Agent Sigrid, an Ice Attack character. During the event, Sigrid's reception rate is significantly boosted, alongside default A-Rank Agents Soukaku (Ice Support) and Lucy (Fire Support). For players building around Ice damage or looking for a fresh Attack option, the banner offers a clear focal point. Soukaku remains a familiar support for Ice teams, while Lucy provides a flexible Fire support option that can fit into a variety of squads.

Is a new Ice Attack Agent enough to justify pulling immediately? The answer depends on account depth. Proxies without a strong Ice damage dealer may find Sigrid's debut more compelling, while those already committed to another Ice roster might weigh the value of the rescreening channels instead. The banner also follows the standard Exclusive Channel rules: the search count for guaranteed signals is cumulative across all Exclusive Channels, but it remains independent of other channel types. In addition, the S-Rank Signal Customization feature allows Proxies to select six S-Rank Agents as customized targets. If the S-Rank obtained is not the featured Agent, it is guaranteed to be one of those six selected Agents. The A-Rank Rate Up feature similarly lets Proxies choose two A-Rank Agents, with default rate-up Agents applying if no customization is made.

"Knight's Extolment" and the W-Engine Channel

Running alongside the Agent banner is "Knight's Extolment," a W-Engine Channel featuring the limited S-Rank W-Engine Knight's Extolment (Attack). The default A-Rank W-Engines Bashful Demon (Support) and Kaboom the Cannon (Support) also receive significantly boosted reception rates. For Proxies who plan to use Sigrid or another Attack-oriented Agent, the signature engine can be a meaningful upgrade, though the usual caution applies: W-Engine channels use their own guarantee count, cumulative across all W-Engine Channels but independent from Agent channels.

The same S-Rank and A-Rank customization systems apply here. Proxies can select six S-Rank W-Engines as customized targets and two A-Rank W-Engines for rate-up. If the S-Rank W-Engine obtained is not the featured one, it is guaranteed to be one of the six selected options. That layer of control can make the channel more attractive for players who want to reduce uncertainty while still chasing a specific engine.

Exclusive Rescreening: Dialyn, Ukinami Yuzuha, and Asaba Harumasa

The Exclusive Rescreening channel offers a different kind of opportunity. The first S-Rank Signal obtained from this channel is guaranteed to be the currently selected limited S-Rank Agent. This is the Special Guarantee, and it applies to all channels in the current Exclusive Rescreening period, triggering only once. The selectable limited S-Rank Agents are Dialyn (Physical Stun), Ukinami Yuzuha (Physical Support), and Asaba Harumasa (Electric Attack). Proxies can switch tabs on the Signal Search page at any time to change the featured Agent, but doing so does not reset the Special Guarantee or the discount.

During each Exclusive Rescreening period, the first 10-Signal Searches are 20% off, costing only Encrypted Master Tape ×8. From the second 10-Signal Searches onward, the original cost returns. This discount applies once per period across all channels in the current Exclusive Rescreening and does not carry over to the next period. The Special Guarantee also resets with each Exclusive Rescreening update, and untriggered guarantee counts do not carry over.

A crucial detail is that the Special Guarantee and the standard guarantee count are tracked separately. When a Proxy obtains an S-Rank Agent for the first time during the current Exclusive Rescreening channel, the Special Guarantee triggers first. After that, subsequent S-Rank Agent signals follow standard guarantee rules, and the standard guarantee count continues to accumulate throughout the channel. In other words, the rescreening banner offers a strong safety net for players who want a specific limited Agent, but it does not replace the normal pity system.

W-Engine Reverberation: Yesterday Calls, Metanukimorphosis, and Zanshin Herb Case

The W-Engine Reverberation channel mirrors the rescreening structure for engines. The first S-Rank Signal obtained is guaranteed to be the currently selected limited S-Rank W-Engine. The selectable options are Yesterday Calls (Stun), Metanukimorphosis (Support), and Zanshin Herb Case (Attack). As with the Agent rescreening, Proxies can switch tabs to change the featured W-Engine, and the first 10-Signal Searches are 20% off at a cost of Encrypted Master Tape ×8. The discount and Special Guarantee are each limited to once per period and reset with each W-Engine Reverberation update.

The Special Guarantee here also triggers before standard guarantee rules, and the two counts remain separate. For Proxies who already have a favored Agent but lack the matching engine, this channel can be a targeted way to close that gap. Still, the same planning question applies: is a guaranteed engine worth the tapes, or would a new Agent expand the roster more meaningfully?

The Final Callback - Audition Stage

A companion event, The Final Callback - Audition Stage, runs during the same period. Proxies must reach Inter-Knot Lv. 8 and unlock the Event feature in the Main Story Prologue - Intermission. The audition stages allow players to try Sigrid (Ice Attack), Remielle (Lumiflux Anomaly), Dialyn (Physical Stun), Ukinami Yuzuha (Physical Support), and Asaba Harumasa (Electric Attack). Clearing a stage for the first time allows Proxies to claim rewards on the results screen.

Final Planning Notes

Channel	Featured Content	Key Detail
"'Till the Ends of the Sky"	Sigrid (Ice Attack), Soukaku, Lucy	Limited S-Rank Agent; Exclusive Channel guarantee count
"Knight's Extolment"	Knight's Extolment (Attack), Bashful Demon, Kaboom the Cannon	Limited S-Rank W-Engine; W-Engine Channel guarantee count
Exclusive Rescreening	Dialyn, Ukinami Yuzuha, Asaba Harumasa	First S-Rank guaranteed as selected Agent; 20% first 10-pull discount
W-Engine Reverberation	Yesterday Calls, Metanukimorphosis, Zanshin Herb Case	First S-Rank guaranteed as selected W-Engine; 20% first 10-pull discount
The Final Callback	Trial stages for five Agents	Requires Inter-Knot Lv. 8; first-clear rewards

The limited S-Rank Agents and W-Engines above will not become available in the Star-Studded Cast Stable Channel. All featured Signals are time-limited, and future reruns are possible but not guaranteed. With three weeks on the calendar, Proxies have room to test Sigrid and the rescreening roster in the audition stages before committing. The smartest approach is to set a clear priority, track guarantee counts carefully, and treat the 20% discount as a bonus rather than a reason to pull without a plan.
