Frequently Asked Questions (F.A.Qs)

❓How often can the passive effect be triggered?

The passive triggers each time a Special or EX Special Attack lands, up to 3 stacks max. Timing and frequent use of these attacks maximize the buff uptime.

❓Is Fusion Compiler effective for burst damage?

Yes, stacking the passive effect rapidly through Special or EX Special Attacks can greatly increase Anomaly Proficiency, making burst damage windows more potent and sustained damage output higher.

❓Where can you get the Fusion Compiler?

The Fusion Compiler is primarily acquired through Signal Search banners (gacha system) or purchased in the Signal Shop using Residual Signal. This makes it accessible but reliant on in-game resources or luck.

❓How do the stacks work?

Each stack from the passive lasts 8 seconds independently, so timing attacks ensures maintaining maximum stacks. Up to 3 stacks can be accumulated, significantly boosting Anomaly Proficiency and thus overall damage for sustained fights.
