Use manager Don + bleed team, get some poise gifts + clear water, and EGO generating gifts. Spam Carmilla on later floors, and make sure to pick as many debuffs that focus on HP, damage taken, defense and so on before you reach floor 5. It's arguably the easiest way to clear all 10 floors, though, I cleared it using rupture insanely easily just win-rating by grabbing all rupture gifts from sweeper and checkup too.
