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

A cost-effective W-Engine that focuses on energy storage. After Nicole modified its internal space, it can now be used as a storage box. While the gold coins stored inside are fake, they may catch greedy Hollow Raiders off guard. Or rather, the operator can simply toss the heavy coins at them and knock them out. "Hurts, doesn't it? Impressive, right? Hmph, that's just what money can do!" — Nicole, gloating after defeating an enemy

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 The Vault in Zenless Zone Zero?

The Vault is a rank A W-Engine built for the Support specialty in Zenless Zone Zero — equip it on an Agent of the matching specialty to unlock the full passive effect; see the base stats and the full R1→R5 Refinement table in the sections above.

Which Agents should use The Vault?

The Vault fits Support specialty Agents best, with 3 recommended characters including Nicole, Soukaku, Lucia — see the full list with portraits in the "Best Agents for this W-Engine" section above.

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

Leveling The Vault through every milestone takes roughly 4 W-Engine components and Denny ×320,000, Support Component ×3, Reinforced Support Component ×26 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 The Vault worth it?

Overclocking only strengthens The Vault'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 The Vault?

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.
