EDIT2: I DID IT GUYS! I used the first team. I got Fire Sky Dancer (Already have Hwahee T.T)

I tried:

Baretta(L), Veromos, Verdehile, Belladeon, Shannon 5*.

Veromos(L), Baretta, Verdehile, Belladeon, Shannon.

Baretta(L), Veromos, Verdehile, Belladeon, Briand.

I can only bring the boss to half of its life. I think one of the things that makes me fail boss stage is that Baretta missing Turbulence because acc-res is a joke.

Do my units lack hp? By the way I can auto GB10 and DB10.
