Gimmicks:
As with all challenge floors you may use no more than 1 of each class type. ie: no double soul weavers.
Three of your 4 units must be Green element.
Momo will put the highest attack unit to sleep when she applies her special debuff.
Momo will do fixed damage when she applies immunity to the team (starts at 2k damage to each unit and scales up to 5k so you need to complete relatively fast before the damage overwhelms you.
Dragons will do an ultimate that applies buff block so you need a good cleansing healer to remove that debuff.
You may not use AOE attacks as AOE attacks give a very strong heal to the entire enemy team. (This includes guardians like Arky)
You must remove the special debuff "Deep Slumber" by attacking the unit with 2 single target attacks. Failure to do this before the enemy takes a turn procs outrage ruining that victory condition.
Needed units:
Champ Zerato or Mort with the highest attack (as they are immune to sleep)
I prefer ChampZ on Violin to remove immunity.
Ray or Destina as they are both strong green healers who are good at debuff removal
Alencia to double attack to remove deep slumber debuff. She makes the fight MUCh easier.
Last unit can be Mort, F.Kluri, or another green DPS unit. As long as the green unit has no AOE attacks. Landy on bloodstone may be a great option.
