1. If I understand correctly, the Karzoug Statue being immune to the Attack trait means that when someone in my party encounters him, I cannot play something like Incendiary Cloud or Toxic Cloud. However, if I managed to use that card earlier on in the turn, could the person encountering the Statue add the dice from the spells to their combat check, since the dice themselves don't have the Attack trait?
2a. I don't have the card text in front of me right now, but I believe the Roc has the power to be shuffled into a random open location if you fail to defeat it. If you fail to defeat a summoned Roc, is it shuffled into a random location deck?
2b. After an encounter with Iesha Foxglove, I've always returned her to the box after the encounter, because that seems like the natural thing to do. Assuming that is the correct thing to do, why isn't she treated like a regular villain and shuffled back into the location decks? I don't have the card right now, but I don't recall seeing any power instructing to banish her after the encounter, even though the Sandpoint Devil has text like that. In this sense, doesn't the rulebook have conflicting instructions regarding villains and summoned encounters?
