Ice and Fire

Yeah, Hangwul is probably waiting with 100 dragons and the number will only increase. I feel like there's almost no chance here.

If that's the case, then it's unlikely that the map can be completed with a hero in the first version.

I'm telling you - the 2nd caravan just arrived. I took troops from it and, using clever logistics and stables, rushed straight to the computer's castle.
The computer has a monthly growth rate, meaning it took the entire army from the castle.
This army can be easily defeated, if it weren't for the Chaos.
Here's how it's done:
We separate 2 stacks of 3 imps each, we don't take devils or demons (they're not very effective anyway).
1. Opposite the bears, we place the 1st stack of 3 imps. In the first turn, they will attack the bears and then be destroyed.
2. Next, the dragons will fall. We also place whatever we don't mind losing there, so they don't use their special ability. And they will also be destroyed.
3. Then the skeletons run. If they use their special ability, they will destroy 10-15 knights. And they will also die. The main thing here is not to let the right stacks get caught by the guardians.
4. The guardians are defeated.
5. The harpooners are finished off, who were previously blinded, then charmed, and then also caught a dispel.
6. All together, the warlords are cut down, who were standing under blindness at the beginning of the battle.
That's the whole battle - minimal losses. Chaos, however, cuts down almost the entire army.
