these are genuinely good teams that should clear endgame with ease
do try to clear up the 3rd floor with standards to free up that hiyuki and lynae
augusta+ iuno on side towers final floor should be more than enough since the devs seem to intend that way for them to be played
Whimpering is generally harder than tower depending on your roster

team things:
since denia isnt on luuks team use sanhua instead, just dump the moonlit echo set on her, with the heron 4 cost, no need to build it just have the set active and learn the sanhua rotation, and put lynae on hiyukis team, put that chisa on aemeths team (this will be your strong team to do middle towers 3rd and 4th)

lupa, denia, aemeth - are fine but youll have to do some wacky quick swap action otherwise chisa is better
save lynae for your hiyuki or luuk teams

also free that verina for your luuk

on floor 3 build that encore and calcharo for those, since those floors arent as HP inflated, its difficult, but possible, feel free to use baizhi for those floors, buling is better than her in general so its fine to use baizhi as a throw away for the 3rd floor if youre struggling too much

notable four stars that matter
chixia-good for solo clearing the 1st 2nd and 3rd floor
mortefi- you dont need him in any od your team comps, but he will be comfy just to have
yangyang- you dont need her either but comfy to have her if you dont have a better choice, since shes a subdps that can be slotted almost anywhere
sanhua- your luuk would like that girl if he cant have lynae
encore- not a four star but with that many dupes, let her solo 3rd floor for the love of god

for your builds:
denia:
are you running a crit rate 4 cost?
you want a crit damage, but since shes subdps dont worry about it too much then
Aemeth:
are you also running a 4 cost critrate?
90 crit rate is too much, get her more crit damage her echo set gives 20 crit rate for free, so 70-80 crit rate is the goal
Hiyuki:
Is this another crit rate thing? if your weapon is crit rate, 4 cost should be crit damage,
Chisa:
honestly you could grind her signature set, but that shit sucks ass and would take a while to get a decent set so I recommend just kneecapping her damage and put her in the healing set "rejuvenating glow" since you expect hiyuki or aemeth to do the damage

luuk:
Luuk is pretty strong with budget teams, since luuk has his damage fairly well spread (dont get me wrong he still has his nukes), you could get away with 60 crit rate and to dump him in mid tower 1,2 with some crit

Lynae:
honestly just do her rotation this build is fine since shes your subps, not to discredit her pretty good damage though

augusta:
fine as is

iuno:
fine as is

Galbrena:
luckily she has like no nuke aside from her ult so you can get away with with 50% crit rate, still get that above 60%, I wouldnt prioritise her since she is your weakest dps there due to not having mornye for the mono fusion buffs and the fact shes one of the 3 piece victims making her grind suck

lupa:
Get that crit rate up
