Despite killing the barbarian companion with money on day 3 or 4, there were big problems, and I ran around with 5 heroes. I was thinking about how to scrape together crystals and money for bears and mages in the Fortress (that was their hideout). The hideout of behemoths, deep in the sands, turned out to be guarded by 50+ snipers, which I didn't see until the opponent was defeated in the maximum crypt.
Thanks for the game.
