Pathfinder Adventure Card Game

How do you lose a scenario?

If at any point you need to advance the hourglass but there are no cards remaining in it, immediately end the current turn; the scenario ends and your party of adventurers loses. You also lose if all of the characters are dead at the same time (see the Dying section for more details). You do not earn the reward on the scenario, and you didn’t complete that scenario. You must replay it and complete it successfully before you can attempt the next scenario.
