HnH would really benefit from some sort of prisoner and rape dynamics.
For instance, once you have someone KOd you can tie them up with rope and carry them off to your rape dungeon. Optionally you can rape them in the woods while they are tied up, maybe each time you rape them one of their attributes goes down a point and you get a buff called "Rapist's Lust"
I figure this works since they wont be able to reincarnate if they're a prisoner, you can just keep them in your rape dungeon until someone tries to rescue them.
I can't imagine how much fun it would be to carry Painhertz off to the rape dungeon.
