On the second week I went into a Griffin Conservatory without magic and with weak skills; it turned out to be a max-level one. I thought I wouldn't get out, but I got lucky — manticores paralyzed a slot of griffins, barely broke it — I traded all my troops for 4 angels. Then I snowballed and cleared 10 Dragon Utopias in 2 weeks.
And here's the finale where the opponent attacks with bracers. My imps at 3.3k helped take down the demons.
Thanks for the game!
