Ass Pull: Grinwoody and Ironfist have been super high-ranking moles for the Order of the Broken Eye this whole time?!
Call a Rabbit a "Smeerp": Almost always played straight - The writer goes out of his way to use off-beat terms for most everything in order to give the world more flavour. For example: "Alcaldesa" = "Mayor", "Tribadist" = "Lesbian". At one point in the series Kip and Teia have a conversation about whether or not Kip is 'homosexual'. The lack of an in-world term for 'homosexual' is a little jarring and kind of breaks the immersion.
Crazy Awesome: Seems to be the entire point of Gunner. In particular, when he has a clear shot on Gavin who's escaping slavery, but spares him, only to then jump off the prow of the ship he was boarding, managing to grab onto Gavin's ship and climb up and claim that Gavin owes him for sparing his life. All so that he could get away from another pirate.
He also describes the process of shooting as firing a projectile that tears through the fabric of time and space to where the target will be, and many other bombastic, passionate terms.
Chaotic Good, Chaotic Neutral, Chaotic Evil: Chaotic in general, are the Green Drafters. Green Luxin is described as being wild freedom. A drafter or colour wight values freedom over all else. It's not that they disdain the law, but that they don't even realize the law exists.
Fridge Logic: How was Gavin planning to dye bread infrared or ultraviolet if his prisoner had made it that far?
Except his brother himself figured out the prison most likely only went to yellow, since making a cell out of oiley orange or sludge-like red would be impossible, let alone superviolet or sub-red. So there'd be no need for the "invisible" colored bread.
Lawful Good, Lawful Neutral, Lawful Evil: On the other hand, Blue Drafters are ruled entirely by logic. As Blue Luxin is as solid and rigid as glass, blue drafters always think in the exact. Even as colour wights everything is done as precisely as possible.
Nightmare Fuel: The experience of the Nine Kings card for Black Luxin begins with a young child's happy recollection of a fun morning at the family home. We don't see how it ends.
The Woobie: Kip is the prime example of this. Lived in a backwater shithole in the worst-off Satrapy, where he suffered All Of The Other Reinder from his fellow villagers and horrific abuse at the hands of his drug-addicted mother, until all of them were slaughtered when he was fifteen. It gets better for him in some ways, in others it only gets worse as the books go on. By the end of the first book, he's afflicted with what may be PSTD from participation in the Battle of Garriston. Regardless of what it is, he's shown to badly traumatised by it. Its shown that he often has nightmares about the bloodbath he single-handedly inflicted, and its implied he doesn't get much sleep.
Fake Gavin. Karris' backstory is a big Tear Jerker, too. Fake Dazen in the second installment might qualify, as well. As we learn more about Ironfist, he manages fall under this banner as well.
Jerkass Woobie: Fake Gavin, heavy on the woobie, light on the jerkass. Fake Dazen, EXTREMELY HEAVY on the jerkass but a woobie because its implied to be a result of his father's influence and years of captivity.
