Hey! Thanks for playing and asking some questions, it really helps me think about what i need to clarify in my next edit:
1. Face cards go above 10. A jack is a 11, Queen an 12, King a 13.
2. You just finish out the dungeon by completing the last room with wherever you decided you wanted the end of it to be beforehand.
3. yes! This is a big clarification I need to edit: you just reshuffle it.
4. of course. Your HP pile will be the 3 other Ace cards (if you're level 1, or Twos if you're lvl 2, etc.) The draw pile will just be the remaining cards. Your loot pile is empty, you just add to it as you pick up loot. And the Discard pile begins empty as well, you add to it as you discard cards that you draw.
