K so I gave it a go.... and it still not possible for me. I suppose a full team of 6* all beefed up with ampys and skill blooms is necessary for this.
I am of course talking about the Mirror misisons (you know, the one with the blue ghostly mirror image of some of the Flower Knights).
Like hell, a good amount of my girls are bloomed and yet, other than Team1 that has 3 rainbows in it, they barely scratch them.
Maybe I should rebuild the teams to go for single attack ultimates, and try to nuke em, but thats still wont be enough.
I really dont see any other way to do this than to have Team 1 be composed fully of 6* (and the more useful ones at that.) and use it to do like 80% of the damage and hope the other 3 teams of 5* can deal the last 20% > which means I cant do that anyway since I dont have a team of 6* at the moment. Siiigh.
