How is co-operative play made more difficult in the Something Wicked expansion for A Touch of Evil?
Unfortunately, Flying Frog Productions seems to be very worried that people will not buy their expansions if the post the rules for them. With that being said, what the most likely mean by, &quot;expanded challenge for cooperative play,&quot; is that a new Advanced Cooperative Mystery Phase Chart is rolled on (2d6) versus the old chart (1d6 - quoted below) before drawing and reading the Mystery Card.

1 Darkness Falls - The Shadow Track immediately moves 2 Steps closer to Darkness. The Heroes may collectively take 5 Wounds divided as they see fit to prevent this.
2 Creeping Shadow - The Shadow Track immediately moves 1 Step closer to Darkness. The Heroes may collectively take 3 Wounds divided as they see fit to prevent this.
3-4 Minion Attack! - Roll once on the Villain’s Minion Chart and place that Minion at a Random Location.
5-6 Scattered Clues - Draw a Random Location and place 2 Investigation in that space.
