Used all restarts, 2 external dragon dwellings spawned under the castle, by week 1 day 12 I already had 3 dragons, then I cleared a Pandora's Box with 9 Necromancy upgrades (lost a dragon) thinking it was easy (and there was 10k experience, leveled up my Gremlins), but nearby there was a Pandora's Box guarded by Griffins with 10k experience. Collected everything on the respawn and by week 1 day 22 I was boosted before ГО, took one Dragon Utopia for stats (+5 +6 all stats + shield +6) but left all dragons there and a nearby Pandora's Box with all air elementals. Covered the opponent's army with a slow artifact (there was Armor of the Damned and +1 speed).
Thanks for the game!
