Catharsis Sagas: Nocturne

Upon Ni Nan, The Soul Eater's entry into the world of Catharsis, a demon targeted him for a shady deal; however, he beat this demon at its own game, tricking it and consuming its essence. Now, he hunts monsters to claim their souls, simultaneously preventing the world from falling into chaos. Catharsis Sagas are true solo game boxes that include one character & one boss. If you own the base game, the boss plays up to five players. The game requires strategy, cooperation, and a touch of luck to succeed as the party fights through traps, monsters, and more. You will hunt down the boss while going through an epic narrative. Roll your dice to activate your powers, but be warned, your powers are also your health. You must carefully decide when it's wise to activate a power and how to resolve damage. Spend your morale wisely, or else you and your party will fall to the corruption of Verity. —description from the description
