...Ive done this. this isnt that hard. The zoom attack is an easy dodge, but the double slam is the one you have to watch out for. i just look at my character's legs and when i see the statue's bottom part near my characters legs, i dodge.
I've helped people beat that floor with same scenario multiple times: they die in the start and i clutch alone. What's more to say, i have mastered ultra instinct. Also, how much max hp did you freaking have? Despite having like 25 hp, you were for some reason in orange color.
They got 2 defense, ball isn't at all effective against enemies with high defense, cuz it's pretty much the only weapon that is blocked by enemy defense.
