If Stannis was not too stiff-necked to accept their terms, the Braavosi would give him all the gold and silver he required, coin enough to buy a dozen sellsword companies, to bribe a hundred lords, to keep his men paid, fed, clothed, and armed.

Rules FAQ

  • Support from the Iron Bank will not reduce the cost to marshal a card into shadows, because marshaling a card into shadows is not considered to be marshaling a card with any of that card's characteristics. It will also not reduce the cost to bring locations or attachments out of shadows, as that does not constitute marshaling or playing those cards. It will reduce the cost of playing events from shadows though.
