Use this Crow guide to compare base and evolved forms, identify the relevant build questions, and confirm live requirements before spending resources.

Guide overview
Treat event availability as historical
The Crow earlier is tied to the Villain Invasion folder, Villain Banner references, and an event shop. It is therefore especially important not to repeat an earlier pity target, coin total, or shop schedule as though it were still live.
Open the current Events and Banner interfaces first. If Crow is not available through that route, retain the guides as a record of how the unit was previously positioned rather than a farming instruction.
Illusion and Black Fire need a current in-game test
earlier guides describe Illusion as a central part of Crow's kit and connect the evolved form to Black Fire and shield-oriented discussions. These are useful reasons to test Crow against the kind of enemy the guide describes, not proof of current damage calculations.
The equipment earlier connects Illusion Crow to the evolved form. Verify the item's current effect and the unit's own condition text before treating it as a mandatory build piece.
