I did it .. it happened, for real, with people who have played before. Against a Disciple, a Champion a Wildlander and a Runemage (all with fairly buff heroes from H&M kits and expansions)
It was a combination of the players getting greedy with a secret room, a lucky Ettin toss so there was no one farming the spawn point for the goblins, and alot of unlucky last minute attempts to finish up mauler who was blocking off the way to 2 search tokens (due to the heretofore mentioned lucky Ettin toss).
Heroes left with a measly 75 gold due to bad fortune in the secret room as well. Shop item pulls were no help - heroes banked the gold.
Next up was Cardinal's Plight, a very tough scenario for fledgeling heroes. The results were predetermined. They tried hard though, really really hard -- did come away with another 200 gold and finally pulled some decent shop upgrades - overall the second half was just brutal because they were so beaten from trying to stop some zombies in encounter 1 that they had no chance of surviving the onslaught of shadow dragons. Not making it past the bouncers severely limited their gold.
Next up next time we play: Rude Awakening --- I am actually going to send them down that rumor because it is just early enough in Act 1 I think I can pull off the win. (I have done it before in the mini campaign when heroes have 5xp by that point in time... this is doable)
I know I will be feeding them some extra gold so I can pursue the reward - but I am thinking it will be worth it. We'll see
