Reports on online games and their confirmations (Autumn 2010 season).

It's called hit-and-run: if a hero, while attacking, uses magic and retreats without losing a single unit!
I was already worried, the opponent killed a harpy)).
I cast a spell, and my hero managed to escape; otherwise, I would have dealt a lot of damage!

5.6. Hit-and-run is prohibited: the attacking hero is not allowed to retreat in the first round of battle if he has used combat magic or any other magic that has inflicted any damage on the opponent. This prohibition does not apply to the hero who is defending.
