Honkai: Star Rail - Apocalyptic Shadow 2.3 - Acheron and Firefly Teams

The first release of the new game mode fighting modified bosses while doing it the fastest in terms of action value left over.
They might have made Argenti's half for her, but still, Firefly is awesome! Gonna try for E1 maybe to ease the skill point usage.
