Following discussions, the anti-gambling rule has been revised:
If both heroes die in a battle between players, and at least one of them had a level of 10 or higher at the time of the battle, then neither of them can be resurrected. If one of them arrived with troops at the beginning of the week, then the autosave from the previous day should be used. If both slots in the tavern are occupied by such heroes, then the autosave should also be used.
Hmm. Perhaps it should be "if both heroes had a level of 10 or higher at the time of the battle." Otherwise, Armageddon's Blade (or The Shadow of Death, etc.) with a high-level hero becomes a super-advantageous situation for one player and a fatal one for the other. We are striving for a more or less balanced game:).
