Pros/Cons

Pros

Flashy, mobile assasin

Good for soloq

Good burst

Better in teamfights than other assasins

Cons

Less upfront burst than other assasins

Getting worse in high elos as her movement is predictable

Vulnerable to hard cc

No competitive plays

Hated by the community(no cap)

Voracity-Passive

Her passive is her resets. Whenever a champion dies who got damaged by Katarina in the last 3 seconds Katarina gets -15 second from her current ability cooldowns.
When Katarina touches a dagger she uses it to deal AOE damage around her.

Bouncing Blades-Q

Katarina throws a dagger to an opponent/jungle monster. The blade bounces to 2 more targets. After it the blade drops to the ground behind the first target.

Preparation-W

Katarina tosses a dagger above her head and gains a burst of movement speed. After a few seconds the dagger will land on the ground.

Shunpo-E

Katarina blinks to an Ally/Jungle monster/Enemy and strikes the nearest enemy in range. Picking up a dagger will reset an amount percentage of Shunpo's cooldown(Sclaing with Shunpo's level). Applies onhit effects and resets the Autoattack timer.

Death Lotus-R

Katarina channels and throws daggers to the 3 nearest enemy champion(including out of vision enemies) scales from AP, AD and Attack speed. Applies Grevious wounds at 60% effectiveness and applies 33% onhit effects. Kraken Slayer's true damage is 25% effective. Movement is disabled int the first and last 0.25 seconds, otherwise movement will cancel the ability.

Best runepage

Conqueror gives you a good early game and the ability to cheese lv2-3 first bloods. The best rune for early skirmishes and teamfights.

Triumph gives you hp after resets, the other two runes are just bad on Katarina.

Legend:Tenacity gives you a bit of protection against cc. Against no cc you can go Legend:Alacrity.

Coup de Grace is good for assasination, but all the runes from this 3 is good on Kat.

Sudden Impact is good on Katarina because she is a blink machine.

Ravenous Hunter with Conqueror is a deadly combo, it gives you enough sustain to go in even if you arent max hp.

Honorable mentions:

Electrocute is a good rune for Katarina as it grants her more burst and better trades, but you will have almost 0 kill pressure in the early laning phase.

Taste of Blood is a good rune for poke lanes where you need more sustain in lane. If you are struggling alot with Luchian/Zed/Tristana etc. you can pick up this rune.

Relentless Hunter is really good if you are snowballing because of the out of combat movement speed.

Resolve has some good perks for sustaining, tenacity and tankiness like Bone plating or Unflinching or Overgrowth.
