Final Fantasy Tactics Advance - Have these two missions on the same place - but one of the laws forbids damage to animals. Guess what is in both those missions!? I don't have an R6 antilaw (Can you even get those?) I don't have doublecast (not an aggressive technique i guess) so the only thing I can do is go in there, use famrit to weaken them all, then stand around and get them to hit me while i counter.

another possibility is to wait a month or two for the laws to shift, but that's a pain.
