After achieving victory in the Faction Challenge yesterday, Nilfgaard fans can now be free from all those other inferior factions in a limited Nilfgaard only arena mode!
Quote from @PlayGwent
The battle against Northern Realms might be over, but don't forget that the Imperial court harbors more danger than most battlefields...
In the new Special Arena mode, you will be able to create your decks with Nilfgaard cards only.
Good luck and have fun!
