I only have Mina, Flare and Francis, at L60, with only fra cis having all awakenings (the rest are at 1 because I don't have compasses needed to give it 80 tries and I really struggle only because of the timer. I just don't seem to do any damage to the boss. So, yeah, I think I'm cooked.

In short I'm asking what it'll do

I use it then what happens?

What is this "burst" that gets triggered to make the thing appear?

And is it better to do new quests everyday or wait for the rewards to cumulate?

Also, considering I have zero of the keys needed to unlock Esther and the new fire girl, which of the 2 should I focus on?
