Questions about the Heroes 4 map editor.

Hmm... Well, you can switch the hero to a different faction. Then, you can add a script where a player of a specific color fights against a certain army, and then our companion will die. But you also need to separate the hero and the companion, so you can place quest gates and set a condition where only a specific hero can pass through, and after the gates, change the companion's color, followed by an invisible battle for the player and the companion's death. In any case, I was also planning to create something similar based on this scenario.
