On the respawn there is one external dwelling of gnolls, a Griffin Conservatory for 10-19 Manticores + a Hat of +4 Knowledge. On the first week I took a secondary Inferno hero, a Moon appeared which leveled up very well, I cleared all the goodies with her, never saw a Dragon Fly Hive, popped out into the center and there was an overview, I saw the opponent's scout hero and was already ready to accept the fight since I had no way to escape.
Thanks for the game!
