An expansion for Dominion built around the theme of going on an epic quest
Adventures, the 9th dominion game, is an expansion introducing 30 new kingdom cards. The unifying theme is cards that involve going on an epic quest. It includes Duration cards that have ongoing effects and Reserve cards that can be used at a later time.
The Dominion rules are extraordinarily comprehensive. For questions regarding how cards interact, if you can, check the individual card entries in the appropriate rulebook(s) and you'll probably find your answer there.
