RG Pinkladies(Flower Saint who talks about dreams)
She's the most useful one I got right now
on the latest castle, 100-105 used Dendrobium and Meconopsis (the rest to build up crit for Dendro) plus I finally found missions that Bluet was good at
and 106-110 used Pinkladies, Tampala, Hydranga, Skunk Vine, Convolvus
that new girl would likely help here if you have her built up(I don't yet)
If I ever get multiples of the FM for solar effectiveness, may put a team together.
