It paid off very generously — 8 heroes and Angels on the first week. I take 2 Dragon Fly Hives and 2 Griffin Conservatories, for a total of 5 Angels and 16 Griffins. I find an external dwelling of Angels on my respawn, take it by the end of the week, and build Castle dwellings. On a scout hero with 131 I take that Dragon Utopia 2 with 10 Angels and 16 Griffins, plus some miscellaneous junk. 9 Angels remain. It gives the Speaker's Hat and Gladius. I set up Archangels and start clearing one Dragon Utopia per day. Took 5 Dragon Utopias total. I planned to just level up Air Magic, but after leveling I saw a nearby enemy Castle and 2 red dots on the overview, so I decided to attack. And those dots turned out to be the main hero and a scout hero with meat.
Thanks for the game!
