Winnie goes from being a scared, lost woman to a Badass Normal with a staff, able to hold her own against the Worldof Badass. Odds are, she and Lunen will become a Battle Couple by the end of the next book.
The crew of the Freewind taking on the Eldritch Abomination living in the Zero Point, using all their skills to survive.
Lunen vs Izoln, with both combatants giving it their all and having one ridiculously awesome showdown.
Winnie figures out that Disana, a seemingly Innocent Fanservice Girl that's been coming on to both her and Lunen, is actually an assassin for the Masked Emperor who poisons Lunen. She then lures her into a one-on-one fight, and manages to, while getting hurt a lot, out-think and fight on even terms with her. And Disana is a full Gold-mooner, meaning she has rapid healing power. That's right, an ordinary girl manages to take on a nearly-invulnerable assassin and wins. There's a reason she's seen as one half of the series' main Battle Couple.
