FAQs
Q1: Will these Firefly buffs make her broken or overpowered compared to other DPS units?
A: Not at all. While substantial, the buffs position her as a top-tier quantum DPS without dethroning established powerhouses like Jingliu. She’ll be incredibly viable but not game-breakingly overpowered—HoYoverse’s balance team did their homework.
Q2: Do I need to rebuild Firefly’s gear after 4.2 patches, or will current builds still work?
A: Current builds absolutely work and will perform better! The buffs are percentage-based increases, meaning your existing ATK, CRIT, and Break Effect stats scale even harder. No regearing needed—just pure damage increase.
