Okay, so I seriously can't beat C9. How is this even supposed to work? All of my runs have been going like this:
Floor 1: Sweep OR get one of my leads bound, kill one Tama with a Sherias, then chip the other and stall up on TamadRa
Floor 2: Kill both with Sherias, either immediately or a few turns in if stalling works out
Floor 3: Stall as much as possible, kill when I have to
Floor 4: Kill with Kanna, sometimes also requires a Sherias
Floor 5: Take most of the way down first turn, finish off second turn
Floor 6: Use Sherias and kill
Floor 7: I'll have always used either both Sherias or Sakuya by this point, so I need to use either both gravities or Sherias plus Nordis to get below HP thresshold. Need to stall 2-3 turns to get the other Sherias back up or get a good board, invariably run out of hearts while stalling and die
I've attempted this probably ten times at this point. I've gotten to Kali like seven or eight of those times and have died on her every single time because I'm just out of resources by then. Am I using something I don't need to at some point? This seems like such RNG horseshit of just whether you always get perfect boards or not, and I have yet to always get perfect boards. What am I doing wrong?
