1: On the location Oubliettte it says "When Closed: You May Heal an Ally". All references in the rules as far as I can find say to heal "the specified number of cards", but the Oubliette does not specify the number of cards to heal. I have so far assumed it to heal one card, but is this an error, or is there some rule I am missing that defines some sort of default number for healing cards?
2: In the "During this Scenario" for DD3B it says to count the cards left in the location to find out if the dragon is defeated. If there are 3 or more, it is undefeated. Is the encountered card still considered part of the location while encountering it?
In case I am unclear, if there are 3 cards left in the location, and I then explore and find the dragon, and manage to beat it, would it be considered defeated or undefeated according to the scenario?
