I also did a "Subdue" action card for PC's, only usable in Green stance and applies more misfortune to the action the lower the CR value of your weapon (e.g., subdue with a knife hard than subdue with a staff or club).
A key point is that this is "an action choice" itself. You don't subdue using your "super great kill em all action card" nor using your magic dart or fireball etc.
It guarantees that when an NPC drops from wound loss they are not dead (well there's chaos star of course...)
Otherwise I have NPCs die when losing all wounds.
Design/narratively, you have to "work" at having prisoners to question.
