I need some help getting this clear in my head. If a model takes an action that targets an enemy model that also has a required TN for it to work, does the defender flip immediately or do they wait until the attacking model meets the TN?

Is the casting considered a simple duel to achieve the TN and then an opposed after the TN is made or is it a strai
