A must-have for fans of the base game, Lords of Waterdeep. This expansion comes with two "Modules", or ways to augment the base game. Each module comes with its own set of buildings, intrigue cards, quests, and lords. There are symbols on the cards to distinguish between "Base Cards/Buildings", "Undermountain Cards/Buildings", and "Skullport Cards/Buildings". Players can choose to play with both modules as well.
