Boosted my Ame no Uzume from level 30 to 90 thanks to my Snow Globe Rouge Dragon. I'm using Durga more often, but she has her uses (and, well, I have more adequate subs for her than for Durga right now).
I'll seriously need TAMADRAs though... Urg.
Sounds like you've got a decent enough team to maybe run Tamadra retreat. That dungeon should hit sooner rather than later, so maybe save a few stones and run that a whole bunch once it pops up. What's your current stamina at?
