Battle-fook systems are wily beasts, especially when combined with situations that call for lethal force. Mind, I suppose that a bit of eromancy to...distract...an enemy could leave them open to a fatal blow.
Speaking of Ero-battles, you might want to check out Monster Girl Dreams on Itch. I suspect that you and most fans of Divine Dawn would enjoy that one, what with being text-heavy and usually light-hearted. That particular game made it law of reality that genuine harm cannot be dealt between people. That makes sex the way to resolve conflict.
