It's been some time since I played this solo. And the whole threat-mechanic threw me completely off at first.yes its a top game.very underrated!...some top game mechanics.and each expansion fetches something new!! the Banshee quest is a real gem of a quest...pretty tough to do we are talking pure tactics!!..not many Dungeon crawlers you can say that about nowadays!.
As I recall I failed 'Well met' the first time. Danor and Madriga made to fast progress and got to the first door well ahead of Rordin and Orlaf. There they were surrounded by skeletons. I think the IO draw some interupts that screwed me.
The second time around I coordinated better between the groups.
The scenario where you meet the troll can have a time problem. I think I opend the last door on the last turn.
Also players are sometimes too intimidated when they see the troll.
When I played against some friends Danor debuffed that guy and the melee-heroes killed him in one turn.
The first real problem is the scenario with the banshee. I lost that... he has a tendency to target poor Danor. And when she gets the interupts from the IO-Deck she gets really powerful.
I hav to throw the game on the table again. I think that was as far as I played solo.
