This expansion introduces a new mechanic: “advance the active
Mystery.” Due to the complexity of Mysteries, this can result in
a number of different effects. When investigators are instructed
to advance the active Mystery, the active investigator resolves
one of the following effects that applies:
^ If the active Mystery requires one or more tokens to be placed
on the card, place one token of that type on the card.
• Clues, Gates, and Monsters placed on the active Mystery
in this way are drawn from the Clue pool, Gate stack, and
Monster cup, respectively.
^ If the active Mystery requires an Epic Monster to be defeated,
place two Health on the card. The Epic Monster’s toughness
is reduced by one for each Health on the active Mystery.
^ If the active Mystery requires an investigator to spend one
or more Clues, place one Clue from the Clue pool on the
card. Any investigator may spend Clues placed on the active
Mystery when resolving an effect of that car
