W-Engine effect24/7While off-field, the equipper's Energy Regen increases by 1.5/s. When the equipper deals Physical DMG with an EX Special Attack, the Daze dealt by the equipper's attacks increases by 9% for 10s, stacking up to 3 times. At 3 stacks, all squad members gain 30% additional CRIT DMG for 40s. Repeated triggers reset the duration. Only one instance of this CRIT DMG boost effect can exist in the same squad. *Stats shown are at Base level.

Verbatim from official game data. Refinement ONLY increases the passive effect values above — it does NOT change Base ATK or the Advanced Stat, which scale with level instead.
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.
