Title says it all. Specifically, when I declare an action, am I required to tell my opponent if there is a Target Number involved or what the TN is? I know I don't have to say if I met it until after the cheat fate phase. For instance, if I am attacking with a CA attacking that has the gun icon with a cast skill of 6, Resist WP, and TN 14, do I just say "Attacking with this ability" or do I say "Attacking with this ability with CA 6, shooting, Resist WP, with a TN".
