that's if you want the mission medals....
in my case, i just want to see if i can clear the thing so after floor 8, i'm throwing my light teams at it....
i have enough water hime to shuffle around, but my water grid sucks... plus i'm missing some hime like Cthulhu and SSR Nike (she does make a 2nd debuffer and SSR healer) so that REALLY doesn't help.
besides, i already seen one hime die on floor 6 so.... yeah. probably time to stop going for just 3 hime and start kicking this tower's ass
