Flight of Fancy in ZZZ: Vivian’s Signature W-Engine Explained for 2026

Flight of Fancy remains one of the most specialized S-rarity W-Engines in Zenless Zone Zero in 2026, and its design makes one point clear: this is Vivian’s weapon first and foremost. The signature W-Engine is built for Attribute Anomaly optimization, but its Passive Effect can only be triggered when its equipper deals Ether DMG to enemies. That combination sharply narrows the list of suitable users. According to the reference guide, Vivian is not merely the top recommendation; she is effectively the only recommended Agent for the gear.

A Signature W-Engine With a Narrow Purpose

Flight of Fancy is an Anomaly W-Engine, which already limits its natural fit to Agents who want Anomaly-related performance. Its additional Ether DMG condition makes the pool even smaller. The reference material describes the W-Engine as amazing for Attribute Anomaly optimization, but it also flags the downside plainly: the Passive Effect depends on the equipper dealing Ether DMG. Because of those restrictions, the recommendation list collapses to Vivian.

For Proxies, this means Flight of Fancy should not be treated as a general-purpose upgrade. It is a targeted signature item for one Agent, and its value rises or falls with Vivian’s place in a roster. Players who do not use Vivian have little reason to pursue it, while Vivian owners gain access to a W-Engine that matches her combat identity and Anomaly role.

Best Characters: Vivian Stands Alone

The reference guide arranges recommended Agents from most to least recommended, but in practice Flight of Fancy has a one-name list: Vivian. The W-Engine’s Anomaly typing and Ether-triggered Passive Effect are too restrictive for broad use. Vivian is the primary recommended Agent, and she is also the signature owner of the weapon.

For team-building, the natural reading is straightforward. Flight of Fancy belongs on Vivian in Ether Anomaly compositions. Other Agents may technically equip W-Engines, but the guide’s recommendation logic does not support treating Flight of Fancy as a flexible alternative. Proxies who are building Vivian should view the W-Engine as part of her dedicated kit; Proxies who are not should keep their resources focused elsewhere.

How to Get Flight of Fancy

Flight of Fancy is an exclusive W-Engine. According to the reference guide, Proxies may not get it by any other means. That makes banner timing the only reliable path to acquisition. Its most recent rerun appeared in the Vibrant Resonance W-Engine banner during Phase 1 of Version 2.3, which ran from October 15 until November 4, 2025. That rerun has since ended.

As of 2026, the key takeaway is that Flight of Fancy is not currently available through the known schedule described in the reference material. Another rerun might occur in the future, so Vivian users should watch official banner announcements and plan their savings accordingly. The W-Engine’s exclusive status means there is no alternate farming route, no standard banner shortcut, and no other acquisition method to rely on.

• ✅ Exclusive W-Engine banner is the only known source.

• ✅ The latest rerun ended on November 4, 2025.

• ✅ As of 2026, no active acquisition route is confirmed in the reference material.

• ✅ A future rerun is possible, but timing is uncertain.

• ❌ It cannot be obtained through other means.

Ascension Materials and Preparation

Ascension planning is still important for anyone who already owns Flight of Fancy or expects to pull it during a future rerun. The reference guide organizes required materials by ascension level and includes a dedicated materials chart. Because the chart is visual, Proxies should verify exact item names and counts in-game before spending resources.

A sensible preparation approach is to secure the W-Engine first, then build ascension materials around the levels the Agent actually needs. For Vivian-focused accounts, early investment in Flight of Fancy can be part of a broader Anomaly build plan. For accounts without Vivian, the material chart is less urgent because the W-Engine’s restrictions make it a poor fit for most other Agents.

What Flight of Fancy Means for 2026

In 2026, Flight of Fancy’s value is clear but narrow. It is a signature S-rarity W-Engine with a strong Anomaly focus, yet its Ether DMG trigger and Anomaly typing keep it tied to Vivian. The reference guide does not present it as a universal option; it presents it as Vivian’s weapon. That makes the decision simple for Proxies: prioritize Flight of Fancy if Vivian is a core part of the roster, and deprioritize it if she is not.

The W-Engine’s most recent rerun is already in the past, and no other acquisition path exists. Vivian users should therefore treat future reruns as the main opportunity and prepare resources in advance. For everyone else, Flight of Fancy remains a highly specialized piece of gear whose best and essentially only recommended home is Vivian.
