You want the hardest setup? I think the most important thing is, that the place of interests are always so far apart as possible.
*Spoiler*
A2 the card with 2 troll and 1 wardrak -> most creatures are now in the south
A3 the card with the wood, they are all in the north,
or
A3 the card with the pergaments (tavern and cavern) then don`t roll the dices for the other 4 pergaments but discard the pergaments for example on 66, 15, 26, 37 (long way to the tree of songs)
C choose the scral with the most bad position. Don`t use the dice.
E You can choose the card dependin on the actual game situation. But I think the 5 (2 Trolls 1 gor) is the hardest
G I think they are equal. Choose the worst one for the actual situation. I think if you take the card with the blue lights in combination with A3 pergaments your group has to take much overtimes. This could be hard.
final enemy: I think the dark temple (card 3 ) is the hardest, but even the siege tower is not easy because he is fast and your team has to collect all the pergaments and blue lights you will have less time to do everything
The gifts of the andori: don`t take the hour glass because you will need time, so it is harder to play without.
I think this is a hard setup. Bad luck (because with good luck it is easy) and write a report here
