So I have done the start turn faltering several times, you really just need to leave a enemy alive, the peasants, mages and mortar enemies can only target the front most if they are in the front. So I just let them falter the part member then move them back. None of there attacks inflict dots, just be mindful of lust to avoid heat dot. There is also a underwear that lower capture chance by 30% which is very good for that goal. It takes a moment, but is quite easy to pull of if you bother to focus it, honestly its one of the easier goals.
