If ally character has status immunity/permanant status X, then . . .
If ally is in Quick state (I don't believe this is an actual status), then . . .
If X value(HP,MP,Gil,Steps,any portion of the time counter, any specific stat, number of items in item list, et cetera) is odd/even, then . . .
If any character has nothing equipped, then . . .
If ally has/does not have an esper equipped, then . . .
If ally has (not) used their esper in this battle, then . . .
If party has certain esper bit activated (meaning you have acquired it) . . .
If magic X is used a certain number of times, then . . .
Perhaps a way to make one enemy counter if you attack another? I don't know if this is in natively or not.
Counter to dog block? Not the status, the actual attack.
