I'm playing Kyra and I've acquired the Boots of Elvenkin which allow me to reveal them to add a dice to an Acrobatics check. But Kyra does not have Acrobatics. I believe that means that if I come across the Ambush barrier which asks for a Dex or Acrobatics check, that if I were to do it as acrobatics it would default to a D4 (because she did not have the ability) and then add a second die using the boots to have 2d4, correct?
It's hard for Kyra to defeat the Ambush, and I believe that means you reshuffle it into the location deck when it is undefeated. But you can run into the situation (if you failed to close the location) where there are no monsters left in the deck and Ambush is the only card. What happens in this case?
