Roaring Fur-nace
Tiger Spirit RisingThe Daze dealt by the equipper's EX Special Attack, Chain Attack, and Ultimate increases by 28%. When using a Chain Attack or Ultimate to deal Fire DMG, the DMG dealt by all squad members increases by 10%, stacking up to 2 times and lasting 30s. The duration of each stack is calculated separately. Triggers once per use of a skill. Only one instance of this effect can exist in the same squad.

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.
