So I'm just wondering if there was something I missed. The strategy that I've been using with my characters is "Burn through the location decks as quickly as possible." This strategy works well most of the time and it has only utterly failed me once... against Black Maaga. I can't even begin to imagine how difficult this scenario would be for individuals who don't power through location decks. I literally cleared all of the locations out in 14 turns (with a bit of help from Black Maaga).
The problem I have is this: This is the only scenario that I have seen where character stats and deck build mean absolutely nothing in the face of the villain. Random d4 rolls dominate the scenario and there is absolutely no way around that issue. The closest thing that you can do to overcoming that mechanic is exploring locations faster than the dice can eat them for Black Maaga, and even after 14 turns and burning through 30 location cards by myself, I still didn't defeat the encounter. And it wasn't because my characters failed, it was because... random. You don't even get an opportunity to fight Black Maaga in the scenario, even though he has a combat check and a bunch of rules printed on his card.
So all I can do at this point is wait 16 more turns and then lose. I didn't run out of time, I didn't fail to defeat enemies, and I didn't even move slower than Black Maaga. It's like playing tic-tac-toe against a random number generator and letting it pick 3 spots before I even get to go. I'm disappointed in this scenario, because it takes no time at all to finish since it chews through cards without encountering them. Unless other members of my playgroup refuse I will strongly suggest taking a bye on this scenario when we get to it. It just isn't worth the short amount of time wasted on it. And the reward for success is basically not worth bothering with anyway.
