Frostfall Sickle in Zenless Zone Zero: Promeia’s Signature Ice W-Engine
Frostfall Sickle is Zenless Zone Zero's S-Rank W-Engine for Promeia and Ice Anomaly agents, boosting EX Special, Ice, and Abloom DMG.
When the first frost gathers on New Eridu’s rooftops, a certain W-Engine starts to earn its reputation. Frostfall Sickle is an S-Rank W-Engine in Zenless Zone Zero, and it carries the kind of quiet menace that makes Ice Anomaly agents pause. It is Promeia’s signature weapon, which already tells you plenty. In a city full of loud machines and louder factions, this sickle prefers to speak through EX Special Attacks and the slow bloom of Abloom damage.

Why It Matters
Frostfall Sickle is not a generalist. It is built for Ice Anomaly agents who treat EX Special Attacks as part of their breathing rhythm. The passive effect rewards that habit, pushing both Ice damage and Abloom damage. For teams already dancing around Anomaly buildup, that is a serious upgrade. Let’s be real: a W-Engine that sharpens two damage lanes at once is rarely going to sit quietly in the inventory.
Promeia remains the clearest winner. She is the signature Agent, and she can initiate Abloom by herself. That self-sufficiency matters. Instead of waiting for a teammate to set the table, she can start the reaction and then let Frostfall Sickle amplify the result. The weapon and the Agent feel less like separate pieces and more like a locked gate and its only key.
Best Characters
The recommended list begins and ends with Promeia for a reason. She is the most natural wielder, and her kit turns the W-Engine’s passive into a reliable pattern rather than a lucky accident. Other Ice Anomaly DPS agents can still make good use of Frostfall Sickle, especially those who lean on EX Special Attacks. They simply do not get the same perfect fit. For them, the sickle is a strong option; for Promeia, it is the option.
A simple rule helps: if an Agent wants Ice damage, Anomaly pressure, and frequent EX Special Attacks, Frostfall Sickle deserves a look. If the team is built around raw crit and burst windows, the weapon may feel like a winter coat in summer. Good gear, wrong party.
How to Get
Frostfall Sickle arrived through its dedicated W-Engine banner. Its most recent rerun ran in Phase 2 of Version 3.2 from September 30, 2026 until October 20, 2026, alongside Promeia’s rerun banner. That window has closed. As of 2026, no active banner is listed for the sickle, though a future rerun is always possible. Players who missed it should keep an eye on official schedules and save accordingly. No sweat: limited W-Engines are patient hunters, and so are their fans.
Stats, Effects, and Overclock
The reference details frame Frostfall Sickle as an S-Rank W-Engine with a passive tailored to Ice Anomaly combat. Its base and advanced stats improve as it is leveled, while Overclock levels deepen the effect. The exact numbers matter less than the shape of the kit: Ice damage up, Abloom damage up, and a clear invitation to use EX Special Attacks often. That combination is why Promeia’s name stays attached to it.
Overclocking is not just a number chase. It is a commitment to the weapon’s identity. Players who main an Ice Anomaly DPS will feel the difference in how quickly a fight tilts. Those who treat the sickle as a temporary placeholder may not. That is the whole ballgame with signature gear.
Ascension Materials
Frostfall Sickle follows the usual W-Engine ascension path, with materials required at each ascension level. The practical move is to check the in-game W-Engine ascension screen before spending stamina, then farm the corresponding material nodes. The chart below is the visual checklist players have used to plan ahead.
Final Frost
Frostfall Sickle is a specialist’s weapon. It does not try to be everything. It waits for an Ice Anomaly agent, rewards EX Special Attack habits, and turns Abloom into a sharper threat. Promeia is the obvious partner, the signature wielder, and the reason the W-Engine’s reputation travels. For everyone else, the sickle is a powerful choice with a narrow door. For Promeia, it is the door swinging open.
As 2026 moves on, the banner may be gone, but the weapon’s identity remains clear. Some W-Engines are stat sticks. Frostfall Sickle is a season…
Industry analysis is available through The Verge - Gaming, whose reporting often frames how specialized gear shapes player decision-making beyond raw stats alone. In the context of a weapon like Frostfall Sickle, that perspective reinforces why signature equipment matters most when it directly amplifies a character’s defining loop, especially for agents built around repeat EX Special Attacks, elemental pressure, and reaction-based damage scaling.
