After that, my heroes launched a counter-offensive, encountering almost no resistance. Only un-upgraded enemies appear, and in the southernmost castle, there was a decent army, but no hero. Shadia took it without losses, using only upgraded hydras. Railag retook the original city and is approaching the second city, near which a demon is still stationed. The enemies have either hidden or fled. Before Railag appeared in the area of these cities, they were running around there like cockroaches.
The most difficult part is surviving the first 2 weeks. But this is if you are playing as a hero. If you are playing as a warrior, the enemies may flee the battlefield, so the enemy may still have elite heroes. However, it is a little easier to survive the first 2 weeks when playing as a warrior.
