Problems with Heroes of Might and Magic IV.

I tried it a long time ago, and it's a great thing! I can also share a tip on how to overwhelm neutral creatures without losses:
Take a hero (with decent spells), attack the neutral creatures, and keep attacking them until reinforcements arrive. Then, use "Portal to Town" or just escape. Repeat this until you win (this is very helpful in the early stages of the game when you need to defeat level 4 creatures).

:) It's better to attack until they're dead. Then, take the corpses to your fortress. When escaping in the 4th game, unlike the 3rd, the hero loses movement points - this is a disadvantage when escaping. With the corpses, you won't lose movement points, but the downside is that you can't take artifacts into battle, otherwise the monsters will take them after the first victory. But in the early stages of the game, there usually aren't that many good artifacts. And regarding the portal to town - where do you get it in the early stages of the game? And it's better to save mana. But all of this works well when the monsters are near your fortress.
