DiamondSwordWoodenSword: There is an order of Battle Mages, who are strong magically, but also can fight with regular weapons, or with magically augmented weapons. One member of it, Klara Huemmel, "Preferred to rely on steel rather than magic. And she outlived many who had different preferences."
AllThereInTheManual: Many of the characters in the book were first publicized in the game.
AndroclesLion: Ariel saves a mouse early on, which gets her the favour of a god
ApocalypticLog: Several of the disposable clones of Albert Morris get to describe their own demise in first person.

DontFearTheReaper: Granny plays poker with Death for child's life. She gets four queens, he gets four aces... but decides to declare "I lose, all I have is four ones" with a wink.
DoomedHometown: A combination of the author's strong support for 'Traditional gender roles' and Values Dissonance with a lot of people means you can expect quite a bit of this. But there are a few cases that are bad even by those standards. Buck and Bruce have several conversations about Hattie and Steve, both of whom work for the Antichrist. Hattie is declared not worth the risk of trying to save her from the Antichrist, since going was 'her choice' and she's possibly banging him already, the filthy slut! Steve is considered a trusted friend despite that he, unlike Hattie, admitted he knows his boss is involved in the murder of another journalist and went suspiciously silent when Buck mentioned his boss might have something to do with the Biblical endtimes.

After the book Payback, she is sent to Switzerland to undergo experimental treatment. She seems to get better, but by the book The Jury, she has a stroke (it is debatable if a stroke is related to AIDS), seems to recover from it, but then passes away without letting any of the Vigilantes visit her! The second one is the fate of Nikki's partner Jenny, who was hit by a drunk trucker and killed off, along with her unborn child in The Jury! The third one is the fate of the Barringtons, a family of criminals who treated horses as profit-making machines and let a number of them starve to death. They appeared in The Jury, but they ran off and vanished before the Vigilantes could go after them. Then, in the book Free Fall, when Nikki asks for an update on the Barringtons, Charles reveals that they are dead. They were located somewhere in Europe, driving a car at a high speed, crashed it, and went up in one mighty fireball of an explosion. Fortunately, the Barringtons were bad guys, so there is little reason to shed tears over them!

SlapOnTheWristNuke: A quarter-gram of positrons mixed with another quarter gram of electrons yields enough photons to cook Nagasaki and at medium altitude should have blinded every naked eye in Rome (including the onlooking crowd in Piazza San Pietro), scorched every non-reflective surface in line of sight and set ablaze every dark surface. It didn't happen that way..^note
SuperStrength: Each element (above) is canceled by its opposite: fire with water, metal with wood, air with earth (or just a pinch of salt), and vice versa. This is mainly used to design prisons and other restraints, but is occasionally used in battle. For example, a Wind-crafter can be cut off from their fury by covering them in enough dirt (or mud), while an earthcrafter merely needs to be suspended above the earth, unable to touch it.
