3.2. Hit-and-run is prohibited: Your hero, attacking an opponent's hero, is not allowed to retreat in the first round of battle if they cast any magic. This prohibition does not apply to a hero who is defending.

I've been playing for a while, but somehow I haven't paid attention to this.

Let's say I have Armageddon or (any other combat spell). I attack an opponent's hero, and in the first round, I cast Armageddon. Then comes the second round. Can I cast Armageddon in the second round and immediately retreat? Without waiting for the opponent to take their turn?

I want to clarify.
