HeroQuest 2 - Character Advancement and Fate points

In this optional variant, the Heroes earn Fate points to spend on their next adventure. Whenever a hero kills a monster or finds a trap, they get a Fate point which can be used in a later Quest. As soon as a Fate point is spent during a game, monsters use White Shields to defend on for the rest of the game.
If the Quest is a success, all surviving heroes get another Fate Point.
