The Death Sentinel guards the Thunderstone, ready to defeat any foolish adventurer who might try to claim the ancient relic. Using the Guardian rules found in Wrath of the Elements, this promo provides another "boss" character to prevent players from obtaining the Thunderstone without first defeating a powerful enemy. The Death Sentinel promo will be given to all players in the 2010 Gen Con Thunderstone Tournament, then made available to all Thunderstone players soon after!
