Dear elizbar1967! You are clearly not Stanislavski. More like Doubting Thomas.
My apologies for the dragon. It was Arcat's dragon. To me, they're all the same.
I've attached a save file from before the final battle for the Necromancer's Castle. This is my first time doing this, so I might have made a mistake.
I would advise you to play the map from the beginning on War difficulty.
