Sony Online Entertainment`s Legends of Norrath has brought its fourth card deck Oathbreaker to the online collectible strategy card game. Scott Martins, director of development, SOE Denver, informs: "With over 250 new card to enhance your strategies, Oathbreaker is a perfect point to jump into the game, just in time for the monthly Legends of Norrath Championship Series." Said tournament brings 32 of the most hardcore manna tappers to Indianapolis`s Gen Con Indy 2008 in the steamy month of August, and a total prize pool of $100,000 probably won`t keep things cool.
