From publisher blurb: Part of the new Chronicles of Darkness rules, Conditions add an additional layer of consequence and reward to certain actions in the Chronicles of Darkness. Various things within the course of a game can cause Conditions. These include exceptional successes, supernatural abilities, and really any situation where the Storyteller thinks they can be used to heighten the drama of a game. Also available in this deck are brand new Numina and Dread Powers cards featuring these rules from the Chronicles of Darkness rulebook for ease of reference at the table.
