My players recently wanted to render an NPC unconscious to make transporting him a little easier. We ended up using the standard damage rules (which state that a character, in this case a henchman, falls unconscious after receiving dramatic wounds equal to their Resolve).
The problem with this tactic is that dramatic wounds are a pretty big deal. They don't go away on their own until the end of the story, and you need surgery to make them go away sooner.
Is there a rule somewhere I'm missing to account for this sort of thing?
