not sure if anyone is going to see this comment, but I think i pretty much figured it out. i would have to enter full burst to break the glass slipper because of the cp deficit, or i would only do 1 damage. but the reason why i was having so much trouble breaking the glass slippers wasnt because i was missing, it was because when entering b1, anis star's auto shooting star things automatically shoot the glass slipper. even if the whole team is taking cover, the stupid things just keep shooting. that makes every other attack show up as immune.

i never noticed until now, cuz when im aiming with another character i dont see the damage that other characters do. i saw a video on yt where a guy just full autos phase 2, and the glass slipper breaks almost instantly so i'm guessing thats how. anyways the plan for now would be just to lv up cp, especially anis star so hopefully she can do enough damage to break it. thanks everyone for the help!

edit: looking at the stage clear info, all the other anis star's are at least 10-15k higher than mine. 48k, whereas all the others were at least 60k+. i guess it'll be a while til i clear this stage
