- A reference guide and manual in Russian for Heroes 3.

It's pointless to argue about casinos :) Better answer this question:
Let's say the month of doubling some creature has arrived...
Does anything influence the number of stacks on the map, their size, the total amount of HP, or the choice of which creature will be doubled? I only know that the more free space there is, the more of them there will be.

They don't double; they simply appear on the map and then grow by 10% per week. I think that eventually, all free space will be filled with monsters. And they always appear with a starting size, which varies within certain limits - well, for example, 10-100 units in a stack (it may depend on the total XP). This can be checked.

By the way, this topic is not useless, especially for "miners," and when playing for experience, as the combination of the month's wandering monsters greatly affects the subsequent situation... Therefore, I appeal to all players to help test this aspect. The save and template for recording test results are in the attachment.

Task: load the save, click "next turn," and record the results in the table - which monster, how many stacks, and the number of monsters in the stacks that appeared on the map. Then again - load and next turn. It's all quite simple. The only thing is to enable the cheat menu to determine the number of monsters. To test statistical events, many tests need to be carried out, preferably on different computers. Therefore, I will be grateful for your help. The results of the research will be reflected in the reference guide.
