The Trader at the Camp near Carsten

The Trader with the new Gwent Cards will be sitting at a bench near a wheel cart. You’ll know its the right one when you talk to him because he is really Gwent obsessed. You’ll be able to buy 4 new cards from him: The Foltest – Son of Medell – Northern Realms Leader card, the new Emhyr var Emreis – Invader of the North – Nilfgaard Leader card, and two times the Gaunter O’Dimm: Darkness – Neutral Gwent card.

Also make sure to challenge him for a gwent game. After you have beaten him you’ll win the new Schirru card from the Scoia’tael faction from him.
