I apparently have a bad habit of reading too fast and missing important keywords. I and my group of players have been satisfying the power challenge claims all wrong. Never taking power from each other and only from the power pool. I have recently remedied this problem, but a new question arises. I am used to being corrected and made to look a fool so here goes. I initiate a power challenge in a 2 player game and my opponent has no one to defend. He has no power on his house card. 2 of my characters have renown. I claim 1 power for the challenge going unopposed, each character claims 1 power for renown, and nothing from my opponent because he can't give me any power from his house. Rite or wrong?!? I didn't see anything about that last one in the rule book, but have glossed over stuff like that in the past.

On a side note, if I were to move power to a card with "Infamy" does that make all power on that card ineligble for the claim of a lost power challenge?

Your initial statement on how that power challenge would resolve is correct: 1 for unopposed on your house, 1 for each renown character onto the characters, and none from your opponent's house to yours. You are also correct that power on characters (either from Infamy or Renown) is not eligible to be moved for the claim of a power challenge.

Sweet, thanx. I think I finally understand it lol
