I'm a complete newbie, so I have a corresponding question. :)
A couple of years ago, I played Heroes 5 at a friend's house, and in her game, you could upgrade monsters in the castle not just once, but twice.
Now, I bought the Gold Edition of Heroes 5 on a disc. But, unfortunately, I didn't find this option there.
Can you tell me if this is some kind of additional part or a patch?!
