Spectral Gaze is an S-rank W-Engine in Zenless Zone Zero, and it occupies a narrow but brilliant lane: it is the signature weapon of Trigger, an Electric Stun Agent whose kit revolves around Aftershocks. For Proxies who field Trigger, the W-Engine is less an optional upgrade and more a structural keystone—a device that sharpens her CRIT Rate, strips DEF from targets, and converts Electric Aftershock damage into a towering Impact payoff. For everyone else, it is a beautifully specialized tool with a lock shaped only for one key.

Stats and Effects ⚡

Spectral Gaze is an S-rarity W-Engine. Its effect profile blends offense and stun utility in a way that few other W-Engines attempt. The core benefits are:

  • 🎯 CRIT Rate increase, enabling hybrid DPS/Stun builds rather than forcing Trigger into a pure stun role.

  • 🛡️ Massive DEF shred on targets, which amplifies the whole team's damage against armored enemies.

  • 💥 A passive effect that grants immense Impact when the wielder deals Electric DMG via Aftershocks.

The last clause is the important one. Spectral Gaze does not reward generic Electric damage; it rewards the specific rhythm of Aftershock hits. That makes the W-Engine behave like a tuning fork pressed against a live wire—every Electric Aftershock makes the effect resonate, and the resulting Impact spike is what turns Trigger from a disruptive stunner into a control engine.

The DEF shred is equally notable. Against high-defense bosses, it works like a can opener for armored foes, peeling away protection before the main course of damage arrives. The CRIT Rate boost keeps Trigger's personal damage from becoming an afterthought, which matters in a meta where Stun Agents are increasingly expected to contribute damage during stun windows.

Best Characters 🎭

The recommended agents for this W-Engine are arranged from most to least recommended. In practice, that list has one entry:

  1. Trigger — the signature wielder, and the only Agent who fully satisfies the Electric Aftershock condition.

There is no credible second option at present. Spectral Gaze is not a generalist stat stick; it is a keyed ignition system. Without Electric Aftershocks, the W-Engine is a lighthouse with no coastline—powerful, but directionless. Other Electric Agents may appreciate the CRIT Rate, yet they cannot reliably trigger the passive's Impact gain or the full DEF shred loop.

Trigger's best builds and teams therefore treat Spectral Gaze as the default premium choice. The W-Engine supports a hybrid DPS/Stun pattern: Trigger applies Electric Aftershocks, the passive stacks Impact, and the DEF shred makes each stun window more lethal for the team's burst damage dealer. In teams where Trigger is the only Stun Agent, this compression of roles is especially valuable.

How to Get 🎰

Spectral Gaze is an exclusive W-Engine. Proxies cannot obtain it through the standard W-Engine pool, crafting, or any other permanent means. It appears only on selected W-Engine banners.

Its most recent confirmed rerun was in the Vibrant Resonance W-Engine Banner during Phase 1 of Version 2.2, which ran from September 4 to September 24, 2025, alongside Trigger's rerun banner. That banner has ended. As of 2026, there has been no further confirmed rerun, so the only reliable path is to wait for a future banner revival. Because the W-Engine is tied so tightly to Trigger, Proxies interested in it should also watch for Trigger reruns; the two are usually marketed as a pair.

Update Levels & Effects 🔧

Spectral Gaze scales through its update levels, with each rank improving the potency of its signature effects. The pattern is familiar for S-rank W-Engines: the CRIT Rate contribution, the DEF shred value, and the Impact bonus all move upward as the W-Engine is upgraded. The exact numbers should be checked in-game, but the design intent is clear—higher update levels make Trigger's Aftershock windows more explosive and her stun pressure more consistent.

Because the passive is conditional, upgrade value is concentrated in teams that can maintain Electric Aftershock coverage. A high-update Spectral Gaze on Trigger is a genuine power spike; the same W-Engine on an off-kit Agent is mostly a CRIT Rate stat stick with a dormant passive.

Materials 🧰

Ascension materials for Spectral Gaze follow the standard W-Engine upgrade path. The per-level breakdown is shown in the chart below, and Proxies should prefarm the usual W-Engine chips and associated upgrade materials before pulling.

The material demands are front-loaded in the usual way: early ascensions are inexpensive, while the final ranks require the rarest chips and a meaningful amount of Dennies. For Trigger owners, the investment is straightforward—Spectral Gaze is her signature weapon, and its effects are tailored to her Aftershock cadence.

Final Thoughts 🧠

Spectral Gaze is a specialist's W-Engine with a sharpened identity. It offers CRIT Rate for hybrid builds, DEF shred for team amplification, and an Impact passive that rewards precise Electric Aftershock play. Its weakness is equally clear: it is not portable. Trigger is the only recommended wielder, and Proxies without her should treat the W-Engine as a future project rather than a universal upgrade. For Trigger mains, however, Spectral Gaze is the difference between a stun unit and a stun engine—a weapon that turns Electric static into structural pressure.
