I think the knock out option needs a lot more uses. So far, I have tried it on a few bosses, and a few other people who seemed interesting/important. But none of them had anything special to say, or gave me an altered quest or anything. Wouldn't it make sense if we can, for example, knock someone out, and then after combat, wake them up to, for instance, extort/blackmmail them? something along the lines of: 'you have one last chance, if you tell me xxxxx then I will let you live'
