Dwellings: 2, 4, 4, 6
No more rest stops. I needed to rush the demon, ideally on day 3, so I needed to maintain a good pace. The heroes didn't start well and weren't leveling up effectively. I was already preparing to mine Iris, but on day 3, she dropped from a dungeon, which was great.
In the middle of the second week, I found a treasure, a very rich one. I immediately built maxed-out crypts and two maxed-out towers, and a grove, which gave me a lot of money. At the beginning of the third week, I found another treasure, and I was lucky again; the nearest portal was in the side center. The treasure contained an angel dwelling, 2 maxed-out temples, and two mini-utopias. The artifacts weren't great, but I found a staff in the shop.
The demon wasn't coming, so I cleared the treasure and headed towards the enemy. The final battle took place in the field. Griffins and unicorns initially wiped out half of my army, but then, with vampirism and demons, I won.
Thanks for the game.
