In the Dark Elements expansion, the overlord is replaced by an
overlord track and a deck of monster activation cards, which control the
monsters you encounter. Your heroes must battle through waves of
monsters to escape your fate, but you still have a chance to gain
experience and grab items along the way. Dark Elements simulates a mini campaign in one night, offering all the excitement and adventure of Descent in a fully cooperative environment.
*The Lair of the Wyrm expansion is required to play the Dark Elements cooperative adventure. In addition, the rules for Dark Elements are not included in the box. The rules are available for free download from the Descent: Journeys in the Dark Second Edition support section.
