Boss Monster Gameplay

We have provided rules for all 5 phases below:

  1. To start the beginning of the turn phase, reveal one hero per player from the ordinary hero deck.
  2. Place these heroes in order beside the deck.
  3. Each player will now draw one room card.
  4. For the build phase, players will place one room facedown in their dungeon.
  5. Until these cards are revealed, players may use spells or activate card abilities.
  6. During the bait phase, spells and abilities cannot be used.
  7. Each player will check their dungeon to see if any of their symbols match the revealed heroes.
  8. If your symbols match, place the hero on the far left of your dungeon. In the event of a tie, the hero stays where it is.
  9. To begin the adventure phase, move your heroes throughout your rooms and apply abilities.
  10. When a hero exits a room with damage equal to its health, it will die.
  11. Defeated heroes are placed facedown to the right of your boss. This will now represent a soul you have collected.
  12. To win the game, you need to collect 10 souls.
  13. However, if the hero remains undefeated and reaches your boss monster it stays faceup and represents a wound.
  14. Collect 5 wounds and you are out the game.
  15. During the end phase, any rooms with end of turn effects are resolved.
  16. If all players meet the winning or losing conditions, subtract your wound from your souls to reveal the winner.
