From the publisher's website: Perilous Trials is the second Asylum Pack in the Rituals of the Order cycle for Call of Cthulhu: The Card Game. As Lucy struggles to remember the details of the party, she is approached by the mysterious Mr. Dart who invites her to join a very old, selective order. Perilous Trials is a fixed 60 card Asylum Pack that contains 20 different never-before-seen cards based on the dark mythos of master horror writer H.P. Lovecraft, designed to augment existing decks and add variety to the Call of Cthulhu metagame. This is not a stand-alone deck; you must have additional Call of Cthulhu LCG cards to play.
