6th whale is rather hard tbh. i ain't swimming in 6* gals, do have to admit, got one full group of them. 4/5 fully ampied and 2nd affection'd and whatnot, but that 6-5 still a cointoss for me. wasn't like that in previous ones, sometimes did them on full auto even. seems like stuff buffed the boss dmg output across the board to account for the SB thing and chance.
sure hope i am being paranoid to tell you the truth
