As a militaristic state, it would perhaps come as no surprise that the primary responsibilities of Noxian women are raising strong children and providing succor for husbands who walk the path of soldiery. There are some, however, for whom nurture is not nature, and Katarina is just such a creature. Born the daughter of the feared Noxian General Du Couteau, the girl was always more interested in her father's knives than in the dresses, jewelry, and other trifles that her sisters spent so much time fussing over. A childhood dispute soon unveiled her uncanny knack for bloodshed, and her father, ever the opportunist, happily fostered her killer instincts. After training under the tutelage of the finest assassins the mighty city-state had to offer, Katarina first cut her teeth performing assassinations in the Ionian War. There, her ruthless mastery of the knife and dagger combined with her sadistic temperament to earn her the title Sinister Blade, a moniker that would follow her for the remainder of her career. She is most famous, however, for her exploits in the campaigns against Demacia, especially those surrounding her engagements with the nation's champion, Garen; a rivalry that began when she recovered the remains of Sion from a vanguard under his protection.

With the demand for warfare somewhat arrested by the tenuous peace settling over Valoran, Katarina sought the allure of violence in its last remaining haven: The League of Legends. Some might say it was an inevitability that Katarina's chosen path would draw her to become a champion of the League, continuing to enforce the will of Noxus and bring prestige of war to her noble family. There, she continues to perform her bloody work - esteemed and reviled, feared and adored.

''The Sinister Blade of Noxus is like a black widow - beautiful, but deadly.'' - Garen, the Might of Demacia, following a skirmish in the field

Greetings Summoners: This build for Assasin Katarina.My build gets more kills and carrying best with my playing skills on ranked/custom/pn.

Weak build but katarina is an assassin! Play with care and you should use ultimate in time thats about ur skills.
You can make 1 defanssive item.But this build is better and shupno keeps you alive with spellwamp.

GL&HF

All of the items for assasins.U should make another abiliity item for mejai if the game goes worst and u cannot get stacks.with this build you can get more stacks,katarina is a most effective with ultimate and easy to get stacks with 1 stunner mate and ultimate combo.Take care and play care.
At last:Aegis of legion is a good thing for teamfight for you and your team.Katarina have too low healt bonus.You can make supportive healtbonus items like Aegis.

Katarina needs armor on early game i prefer +6 armor ever and %3 lifesteal is good for solotop.
Offence is better for katarina.Summoner's insight my choice 15 sec cd reduction for flash and reduces teleport's delay is better for farming going teamfight and other...

Runing is important for katarina i prefer flat ap and dodge cause of:Kata still makes high ap on late game she needs flat ap on early game 120 damage on 1st lvl shunpo not bad for harrassing and farming.

You can chage it for per lvl runes but maximum ap is not problem on late game.Still rebaddons keeps up your ability power.

You should take care on teamfight Katarina is too squishy on fights your team needs one aoe stunner for maximum damage for ultimate.All of disablers focus on kata in teamfight u should be behind your tank.Aegis of legion is a good thing for teamfight for you and your team.

* Try using Killer Instinct's active and Shunpo to increase your survivability while using Death Lotus.
* 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 ally or allied minion can be a great escape tactic.
* You can use your ULTIMATE for stealth champions when they near on you your ultimate opens take care about it.

* Double shunpo: Enemy under the tower with low healt for your shunpo if u can kill him with 1 shunpo your passive resets your shunpo and you can blink your minion/champ and you can escape from tower without getting damage!
