CRIT Rate increases by 25%. When the equipper consumes at least 20 Energy in a single instance, every 20 Energy consumed grants 3s of a buff: when dealing Electric DMG, ignore 28% of the target's DEF. Repeated triggers extend the duration, up to a maximum of 30s. When entering combat, gain 10s of this buff. While the equipper is not the active character, the duration no longer decreases. *Stats shown are at Base level.

How to Get This W-Engine

Pull it from Signal Search using Master Tapes / Encrypted Master Tapes (bought with Polychrome) — S-rank W-Engines get their own banner, usually alongside the matching character's banner.

Trade for it at the Gadget Shop's Box Galaxy section (Sixth Street): costs W-Engine Components + W-Engine Chips + Denny; Chips come from disassembling spare W-Engines.

A handful of A/B-rank W-Engines unlock through Proxy Primer trials or as story/event rewards instead of the gacha — not every W-Engine is pullable.

Official Artwork / Lore

Beneath the cold alloy scales, venom made of data flows. Each flick of the serpent's tongue probes the dark, carving out an electronic circuit that leads the homeless snake back to its "nest." Each cycle of data in and out leaves untraceable fragments of corrupted code — much like its user, driven by instinct to chew through truth's rigid shell. "It says... this time, the target's hiding somewhere nice and warm." — Cissia brushes a hand over the subtly warm serpent head, her smile hovering between danger and anticipation.

How to read this W-Engine page

Every W-Engine has 5 Refinement ranks (R1→R5): refinement ONLY strengthens the passive effect — the numbers in the table above run from left (R1, unrefined) to right (R5, max refinement via 4 duplicates or Overclock materials); Base ATK and the Advanced Stat (CRIT Rate/CRIT DMG/ATK%/PEN Ratio/Anomaly Proficiency...) do NOT change with refinement, only with the engine's level. "Best Agents for this W-Engine" prioritizes agents whose real build actually recommends this engine; if that data isn't available yet, the page falls back to agents sharing the same specialty as a rough guide. "Alternatives of the same specialty" lists other W-Engines with the same role — useful when you don't own the engine shown on this page.

FAQ

What is Serpentine Seeker in Zenless Zone Zero?

Which Agents should use Serpentine Seeker?

How much Denny and material does it take to upgrade Serpentine Seeker, and where do I farm it?

Leveling Serpentine Seeker through every milestone takes roughly 4 W-Engine components and Denny ×400,000, Attack Component ×4, Reinforced Attack Component ×32 Denny combined — the components drop from Combat Simulation; see the exact breakdown per milestone and the Battery cost in the "How Much You Need" and "Where to Farm" sections above.

Is Overclocking Serpentine Seeker worth it?

Overclocking only strengthens Serpentine Seeker's passive effect from ★1 up to ★5 (5 copies) — it never changes Base ATK or the sub-stat, so getting the base copy matters far more; treat extra copies as a bonus.

Where do I get Serpentine Seeker?

Mostly through Signal Search gacha (Polychrome); a few A/B-rank W-Engines are tradeable at the Gadget Shop's Box Galaxy or come from story/event rewards — see the "How to Get" section above for details.
