This is usually where it gets a little awkward for that sort of thing. I recommend setting your Cura gambit a bit lower, maybe fifty or forty percent, if possible. How many quickenings do your characters have? You may have to do a bit of farming, but it really helps to have two per character at this point. You probably can't get it just yet, but it's best to get Charge as soon as possible.

If all else fails, just walk around for a bit to charge up your MP!
