From the website: The critically acclaimed game of dungeon delving, kill-stealing and cooperative - backstabbing becomes even more challenging with the inclusion of a NEW game mechanic, an Event Deck that makes even the most familiar Encounters new again. And mixed among the Events are ways to earn powerful new Relics that confer game changing abilities upon their owners. Plus, this set includes 15 of the deadliest creatures yet. Can you resist the lure of a 14-card hand? Will you succumb to the PVP inducing effects of Voodoo? Or will you become a horrific beast yourself in the final moments and turn on your companions?
