if it were me, then I think you know the answer
Kerria needs every upgrade possible.
Anemone, like Kerria needs every possible upgrade. She is a hybrid that I use all over the place. Best support girl in the game IMHO
Dendro doesnt need an earring slot, but does need skill maxed and ATK at max.(mine will never see the earring or any HP or DEF)
if I need a Raid boss or defensive team I don't use Dendro at all for that.
Once you deal with those three, than worry about the rest.
I like Loquat next with the Dendro setup
Take it or leave it for what its worth
