[HMM V TOURNAMENT] "Best Treasure Hunter"

I had that idea, and once I even got a 2% enlightenment! But I thought the probability was too low, and I guess I wasn't leveling up my hero very well, he was only level 21.

I've played the map three times, and I've never found the training. And if you level up before Mentorship, it will take a very long time, almost impossible to do during a playthrough.

Guys, where can I find maps from previous tournaments? Are they stored somewhere? I have the map from the ghost-collecting tournament, and I want to practice on other maps before the next tournaments.
