Team suggestions or tech for dire pls

I managed to do the gecko already using bina, illuga, Linnea, and zibai. I’m close on the other 2 but I’m still short, and I’m unsure if it’s skill issue or a dmg issue. For the emperor of fire and iron I’m using furina, Escoffier, skirk, and yelan and it’s barely not clearing. As for the stellar conduct boss, I’ve been trying Odette, yae, vodyanitsa, and sandrone. Im probably a few crits away dmg wise but after about 2 hours of attempts I still haven’t managed to clear. So basically I’d just like to know if there’s something else I should try to manage the clear or if I should just crit fish more. (This is also the first Stygian since Stygian released that I haven’t had a place to feasibly use my arle. She’s usually the one to carry me but she’s not good on any of the bosses.)
