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 W-Engine with a component structure adjusted according to specific parameters. It can enhance the defensive capabilities of those who have a certain style of combat. If the user does not meet the requirements for this W-Engine, then carrying it would be like lugging around an over-sized shield in battle.

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.

How much Denny and material does it take to upgrade [Identity] Base, and where do I farm it?

Is Overclocking [Identity] Base worth it?

Overclocking only strengthens [Identity] Base'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.
