Hill of the Dead

AstralLein, Kaspar's army isn't fixed; it grows gradually, albeit not at a rapid pace. Theoretically, it could be structured so that the growth rate depends on the number of towns under the player's control. However, there's a very fine line between making the map too difficult to complete. That's why I left two options: you can finish earlier, but it will be more challenging, or later, and it will be easier.
Again, on any map, if a player has an advantage in terms of troop growth from their towns, they will eventually win. You can adjust the boss's army growth rate so that it increases progressively, but this is a risky approach, as there's a high chance of making the map virtually impossible to complete.
