Firefly E0S0 Herta LC + Ruan Mei E0S1 1 Cycle Beta Showcase vs Argenti MOC 12 (2.3) Side 1 

it doesn't stack

for slow ruan mei build like in the video, it's better to put ddd on hmc (although it's not as ideal as ddd on faster units like sparkle/tingyun)

you might expect around more than 5 cycle clear with asta or bronya, sparkle gives nothing to ff since she is already fast on her own and doesn't scale on crits, and ff's high ult cost means she gain neligible energy from tingyun's ultimate, and bronya+ asta gives little buff with a cost on the sp economy, ff's damage composed of mostly superbreaks damage and though she has the trace for it, subtituting hmc will be a big damage loss (even greater than replacing ruan mei) since hmc enables everyone in the team to deal damage to broken enemies, substituting gallagher with aven will result in considerably slower breaking efficiency (no break = no damage) and higher cycle count too. I'd say currently she only has one good team, but that team is really really good.

@@JigokuHSR okay thanks you very much for your reply, that'll be a great help for my decision to pull her or not !

I prefer ruan mei's for the sp economy and the frontloaded energy (very good for low cycle clear), firefly's LC is good but herta's store LC is not that far behind. But both of their e1 are better than their lightcones, so E1 > S1

firefly has 240 ult cost so energy from teammates won't benefit her (her skill fill her energy by half)

You would need more or less 10 back to back qpq procs to get half of ff's ult

ruan mei

unless you have two copies of memories of the past lc at s3+. I'd say ruan mei

@@JigokuHSR aight tysm

Id say for account wise rm's lc would be good but on the other hand firefly's lc synergizes with ruan mei's passive making more space for her dmg window. In my opinion, if your ruan mei already got 160+ BE outside of battle you dont necessarily need her lc as it would only give +1 sp at that point and 10 energy (dmg% is wasted on break teams) and gallagher already give more that enough with multipilcation lc, so if thats the case ff's lc> rm's

@@ak--dj4qm IM not talk about rm LC, IM talk about rm it self

if you can get a hand on her e1, then bronya can work, but e0 rm + e0 ff > bronya + e1 ff, she is very fast and still consume sp even in her enhanced state so using bronya is really sp consuming, with e0 firefly and no ruan mei, asta will work better to deal toughness bar damage for greater breaking efficiency.

there's no must pull! but she is a great unit (and f2p friendly), but I'd say ruan mei + hmc is the core of break teams so if u don't have her yet then ruan mei > ff (unless you like ff more), just pull who you like and build around them
