Some encounter cards give you an option of prevent damage by discarding cards with shield icons.
For example, Fornost's "Deadmen's Dike" card deals 4 damage to your hero, but you can prevent that damage and if you do you get 2 favor and receive training.
What will happen if you have no cards in your life pool, and by discarding cards from your hand to prevent the damage you will end up with 0 cards?
Are you defeated and you don't get the favor and training?
Can you get the training and remain undefeated (since you got 1 card in hand now)?
In case the hero does get the reward and is defeated:
What happens if he had no favor or item? Does he lose a favor / item from the reward?
Does he keep any received skill cards in hand from the reward, or he is required to shuffle it into the life pool?
