I pumped up my elemental damage on ein and cindy as high as i could and then just went all in for damage. in the end i couldnt break the slippers in phase 2 so i had to keep ein in cover most of the time in order to save her burst for the true damage. you could also try crown, liter, ein, helm and alice as a team which did let me break the slippers but didn't make the cut damage wise at my level and resources
