Biting Frost is a weather card. It sets the strength of every non-hero Close Combat unit on both sides to 1. Heroes are immune, and Clear Weather removes it.
Play it when your opponent has a stronger front row than you, or when you rely on Ranged and Siege units yourself.
There are 3 copies. Two come in the starter deck you get in White Orchard, and the third is a random reward for beating gwent players. See Collect ‘Em All for more on random cards.
