I was playin around with lv 80. Finally cleared it just before mtc kicked in barely and in trial mode
had to sacrifice two debuff girls. That is just around a 6000 score couldn't do any better with what I got.
used Snowdrop, Horse Chestnut, Tampala, Kerria, and Hydrangea. and the solar FM that boosts Atk 15% per blast, 3 of the weakness boosters, And the Lycoris change to slice FM.
Took all 15 rounds but it will work
