In need of Limit Break Ideas

I got one for Cecil..it simular to holy spell called "Holly Mist" named after the mist dragon he defeated.

for possibilities of already existing attacks (why does this seem to be forgotten?!)

look something like Pearl, Ice, AuraBolt, Absolute 0 (or was this one only SMRPG...)

or even something like Cold Dust...actually that's it, Cold Dust (maybe, unless you want it to hit more than one)
