Role and build direction

Refresh Cheer On and return field time to the carry. The first job is repeatable buff uptime and a clean hand-off. Choose Energy Regen when missed EX casts break the rotation, and the relevant scaling stat when the buff has not reached its cap. Personal damage is a later investment once the team’s damage window is stable.

Equipment and stat priorities

The equipment table below is a starting point, not a universal ranking. Finish usable main stats before replacing a complete piece for a minor substat upgrade. Read each set’s trigger and each W-Engine’s passive, then check whether your rotation actually sustains them. Premium equipment and duplicate upgrades are not required to begin testing this plan.

Rotation and resource management

Apply Cheer On close to the carry’s damage period. Reach the buff’s ATK requirement at your actual skill level before investing in personal CRIT. Record where the rotation loses time: setup, movement, an unavailable EX, or an interrupted damage sequence. Change one decision at a time and repeat the same encounter. A shorter animation or an extra attack is only an improvement if it preserves the important buffs and resources.

Team selection

Catalog compositions containing Lucy: Jane Doe / Seth Lowell / Lucy; Jane Doe / Burnice White / Lucy; Piper Wheel / Burnice White / Lucy; Soldier 11 / Koleda Belobog / Lucy; Nekomata / Piper Wheel / Lucy; Yixuan / Lighter / Lucy. Use the planner to inspect additional abilities and Bangboo requirements. These are accessible catalog examples rather than the complete current meta. A valid condition does not measure field-time competition or enemy resistance.

PLAN A SQUAD

Shiyu Defense

Coordinate Lucy's setup with the assigned carry. Refresh utility near wave transitions rather than spending the whole buff on travel. Compare support allocation across both sides; the shortest clear comes from two functional squads, not one heavily invested composition.

Deadly Assault

Evaluate repeated cycles over the scoring period. Keep Lucy's role consistent across setup and recovery, and inspect the actual boss mechanics before extending a rotation. Allocate three independent squads first. The strongest-looking single squad may consume a support that another encounter needs more urgently.

Hollow Zero and practical mistakes

Temporary programs can change the value of Lucy's normal build and rotation. Read acquired effects before spending resources in the next room. Her core support can be useful even when the additional condition is inactive. Keep a stable baseline build, then adapt the play sequence to the run instead of farming new equipment for every temporary modifier.
