Some inaccuracies in Heroes of Might and Magic III½.

I've never encountered that before. If you have a lot of mana and your opponent has an army that you don't, it's hard to lose. You move regular creatures around the map, block with dumb golems on one side, and attack on the other, and that's it.

Please excuse me if this is off-topic, and it's just a question, out of curiosity:
the hero was walking around without an army!!! How is that possible:smile07:, I don't understand...

In WoG, there are special creatures that represent the hero on the battlefield. They are called commanders. They will never be visible in the creatures window. But if a hero has such a hidden commander, he doesn't disappear and can "live" on the map. You can read information about the commander at the top, in the hero's information. There is an icon that looks like a handshake. Click on it and you'll see.
