An Arm and a Leg: She allows Bloody Mary to chew her arm off from the wrist up (she'd already eaten the hand) in a play for time.
Anything That Moves: She deconstructs this trope; she starts out the series an unabashed hedonist but gets less and less willing to take sexual risks as the consequences of her actions threaten her relationship with Bernadette.
Clothes Make the Superman: Subverted. Up to Chapter 30: Blackbird, her often absurd self-confidence was directly tied to her jester outfit. In that chapter, it's revealed that she has always been self-confident and the two personalities are simply part of her performance.
Rape as Drama: She's not above submitting to rape, if it's the only way to save the ones she loves. She states outright that her attitude to sexuality makes rape much less traumatic to her than to the average person.
Shameless Fanservice Girl: Understands the nudity taboo most people have, but doesn't believe in it. Extends it from "no nudity taboo" to "no sexuality taboo". Remains mostly tamed due to being in a relationship. Best summed up here.
Talking Is a Free Action: One sometimes wonders if one of her magical powers is to get people to stop fighting as long as her mouth keeps moving. This is also done a lot in the second fight scene between Bloody Mary and Bernadette.
Too Kinky to Torture: She has learned to accept pain rather than fight it, allowing her to be virtually impervious to torture and even mutilation. One scene has her smiling gently as her arm is being eaten, much to the dismay of the person doing the eating.
Fighting Your Friend: Chapter 16: Man-Eating, from Book Zero, is the introduction of Clairen, an old acquaintance of Bernadette. In this chapter, and the next, Chapter 17: The Battle Of Old Friends, Bern is forced to battle against her, as part of her deal with Seraph.
The Worf Effect: She can't do well against spellcasters and magically-enhanced fighters despite being invincible against any normal swordsman.
A young skilled rogue, and the son of a famous knight. In an effort to raise enough money to pay for an operation to restore his mother's eyesight, he falls into the dangerous world of underground gambling. When he is caught using sleight of hand at a high stakes poker game, his life as he knew it would change...
Stalker with a Crush: His stated goal for going with the party is to wait until Maytag and Bern have a fight and steal her away for himself. Granted, this was before he was demoted. He's mostly over it in more recent chapters.
Allies and friends
Self-proclaimed "toughest mercenary" of Vestige Town, and self-appointed "bodyguard" of Maytag. He only appears in Book Zero.
Wouldn't Hit a Girl: The reason he rejected to fight against the Black Poison Angels. So much that Maytag has a hard time insisting until he gets to fight against them, and even then he doesn't fight with all of his will.
Too Clever by Half: More than once, her massive overconfidence in her own abilities has been painfully undercut by her corresponding lack of practical experience (specifically, a tendency to overextend herself and run out of juice before the job is done).
Blessed with Suck: His curse allows him to see everyone's weaknesses has left him a bitter misanthrope.
Hidden Eyes: Initially, this was assumed to be because he was always so horribly depressing, emo, sarky, goth, etc. It turns out that he had magical eyes which caused him to only see the worst in people, causing both his BAD attitude and his hiding of his very weird-looking eyes.
