Nazir appeared in the tavern right away, and I chose him as the main hero. The third hero was Casper; I used him to collect money starting from the second week. In the first week, there was a shortage of gold – very little was generated, and the entrance to the adjacent area was also empty. I even had to skip a day of construction. But in the second week, everything seemed to work out; the hero leveled up well, quickly acquired pyromancy, and his spell power increased normally. Casper started bringing in profits from the second adjacent area. Without logistics, it took a while to move around, but I managed to get defense.
Grok started to pull ahead from the middle of the third week... While I was clearing the resource area, he broke through to my adjacent area – he was probably already looking for a treasure, and it seems he found it by the end of the fourth week. Since I was heading towards Chaos, there was no point in delaying, so I didn't even go to the central areas – I attacked the city at level 21 and started to attack the main outpost. In the Chaos castle, they didn't let me in at all, but I bought some great artifacts – on the fourth week, I got the Staff of Sar and the Phoenix Cloak, and on the fifth week, the Tome of Chaos. By the end of the fifth week, I finally reached the enemy's city. Grok was already very powerful: several gnome artifacts, the Armor of the Forgotten, etc., and he also had Light and Armageddon magic (I checked with Clairvoyance). But Armageddon did the trick, and I also had decent defense and a defense skill... If I hadn't made it in the fifth week, I might not have been able to hold out. And in the battle, I think I should have cast Armageddon on the pitfiends... Here is a demo of the final battle:
