However, if there is only 1 party member left, they will escape safely.
You can't easily retreat from the Darkest Dungeon, either, should things go south: when you retreat, a random party member will die (representing them holding off the monsters to buy their comrades time to escape).
Almost every attack will induce stress, every blight and bleed deals high damage, and every encounter has a good chance to be the last. First and foremost - the Darkest Dungeon is nothing like the challenges you’ve faced before.
