Also, her final showdown with Ozorne in "Realms of the Gods", where she spends the entire fight dodging every piece of magic the Stormwing throws at her by constantly shape shifting, and when she has no magic left, stabbing him in the chest with her badger claw.
On a related note, Numair turning a man into a tree. And just to be safe, making a tree (some tree, somewhere) into a person so the universe it balanced.
The last bit of Ulasim's speech after the riot: "Any child knows it is better to swim with the tide than against it. We attack in force at dawn."
The Growl in Terrier.
I'd heard of a Growl, when Dogs took up a challenge. It meant ill for the Rats that made them voice it. But it was one thing to hear of it, another thing to sit in the Mantel and Pullet and hear that rumbling snarl come from dozens of throats.
Alanna's duel against Dain of Melor. She's only a squire at the time and beats the snot out of him after her breaks the rules and tries to kill her. All with her less domainant hand. Which is related to another Crowning Moment Of Awesome, namely learning to sword fight with her left hand and a too heavy sword after her right arm is broken.
The climax of Lioness Rampant. Pure chaos as the various evil plans all come crashing together, and just about every named character gets something big to do.
Kel spends her first year as a page enduring constant and vicious bullying. Soon, she figures out that someone weighted her lance with lead to make her look awkward. When it breaks, she gets handed another such lance by Joren. This is so unjust that Kel finally breaks...by going into Tranquil Fury so calm that nobody can tell, and then becoming the first trainee to hit the target. With her weighted lance. She goes on training with not only the weighted lance, but weighted axe and sword as well.
To add onto this? She keeps pushing herself until she can hit dead center every time, uses a willow ring (most rings are oak) to train with, and becomes the best in not only her class, but the entirety of the pages. By Squire, she only loses jousting matches when she wants to, to keep people from thinking she's enchanted. (Except when she jousts against Wyldon, but everyone loses to him.)
George Cooper. He's amazing with knives, incredibly intelligent, and the King of Thieves by the age of seventeen.
Alanna's entire fight with Ralon in The First Adventure. He's bigger than her, and has been tormenting her for months, and yet she refuses any help from her friends and takes him on alone. And completely trounces him.
The attack on the hydra monster in The Realms of the Gods, including the Badger chewing through a skull to the brain, and a flock of starlings mobbing it.
Kel facing her greatest fear ever, heights, and risking having to retake all her years as a page, just to save Lalasla and Jump after they've been kidnapped.
How about when she takes command of her group of pages when they're attacked by a large group of raiders, keeping them all alive against the odds?
Kel's defiance of the Standard Female Grab Area in Squire. When Lerant insults her and grabs her arm, she simply flexes her bicep, which becomes so big that he's forced to let go.
Neal dealing with Tobe's abusive former master, by putting a spell on him that will make him feel every piece of physical abuse he gives out himself. Just to make sure the man understands that it's real, Neal says "Mithros cut me down if I lie."
Kel's mission to rescue the refugees who were kidnapped from Haven. Throughout the whole thing she proves herself an excellent tactician once again, whittling down the enemy's far superior numbers using every trick she's learned over the course of four books, before the final showdown with Stenmun and Blayce.
The female Balitangs all get some good hits in during the final chapter of Trickster's Choice, with Sarai turning on Bronau once and for all, Winnamine killing one of his henchmen with a candlelabra, and Dove getting rid of the bastard for good with the arrows Nawat gave her. And then there's Nawat pulling a Big Damn Heroes by convincing the other crows to take human form for a little while.
The raka citizenry rising to the defense of the Balitangs when the King's Watch tries to assassinate them. Centuries of oppression finally begin to be thrown off for good. And including the amazing image of two women, one raka and one luarin, working side by side to fight the soldiers, giving hope that there can be peace between the two sides after the rebellion ends.
