So… Where should me and my girls be at for those points in the story/game? Most of my girls are on level 80 DL4. Things was go great to ok to ch.9-4 onward were they start to give my girls a real hard time.
For ch 9 E, get your dolls up to level 90, so that you can x5 dummy link them. Fairies and MG SG squads can also be helpful.
Also bring in an op friend echelon if things get too difficult.
