but now I have a case where I have 2 Numbing Fear cards in my progress zone from drawing them consecutively during the same Turn. Each card say I cannot use Wrath intent from my Influence cards this Turn and to discard the card at the end of the Turn. Do I discard both of them at the same time? It's what I did but found it rather convenient actually so I thought to ask for a second opinion!
Yes, in this case, you discard both of them at the same time.
