Whenever an enemy champion dies that Katarina has damaged recently, her remaining ability cooldowns are dramatically reduced.

If Katarina picks up a Dagger, she uses it to slash through all nearby enemies, dealing magic damage.

Playing as Katarina

Picking up Daggers will significantly reduce Shunpo's cooldown.
Try waiting until the other team is distracted with fighting your team, and use Shunpo to teleport into the fray and unleash a devastating Death Lotus.
Using Shunpo on an allied Champion, Dagger, or minion can be a great escape tactic.

Playing against Katarina

Katarina's abilities deal magic damage, so even if she's building Attack Damage items, get magic resistance to counter her.
Try to save a disable for when Katarina uses her Death Lotus.

Lore

Decisive in judgment and lethal in combat, Katarina is a Noxian assassin of the highest caliber. Eldest daughter to the legendary General Du Couteau, she made her talents known with swift kills against unsuspecting enemies. Her fiery ambition has driven her to pursue heavily-guarded targets, even at the risk of endangering her allies—but no matter the mission, Katarina will not hesitate to execute her duty amid a whirlwind of serrated daggers.
