there are times when the GM will bend or break the rules of the game system in order to allow his players to maintain their characters. Just as he sometimes metes out punishment for infractions, the GM at other times intervenes benevolently, spreading his aegis over the PCs to save them from probabilities gone awry. To put it bluntly, when play is at a low ebb, or it is quite likely that the players' characters are about to suffer undue loss or extinction, the GM cheats and decrees otherwise. Opponents miss their blows, PCs manage to strike their foes, and various sorts of miracles occur. This is wrong only when it is done too liberally or when it is unwarranted.
