- use magic in battle twice per turn
Available in older versions. In SoD 3.2, Platinum (4.0), HDmod, this bug does not exist. Perhaps it would be worth specifying in the rules which versions can be played?
Of course, a starting save is needed.
1. It is definitely necessary to specify: which version of "Heroes" to use (SoD 3.0/3.1/3.2/Complete), with or without the HD mod; if so, then, again: which version, with the option to "fix game bugs," etc.
Double casting of magic, I think, should definitely not be allowed: it's still a cheat.
2. All players must start the game from the same, organizer-made, starting save: only then will they be on equal footing!
