This build is about Katarina, the Sinister Blade. Katarina is an AP Carry who outstands in teamfights. Katarina can clear out minion waves on a short time period. Katarina is a strong and versatile ganker who can easily get to her target and get away from her target.

Although you can easily jump into teamfights and get loads of kills, Katarina isn't a tank. She can't 1v5 the whole enemy team on a normal score. Katarina can only be very effective when she gets kills early game. Katarina is a melee champ, which makes it a bit harder for her to get easy minion kills early game.

This is my first guide I've ever made.

Pros:
+ Fast minion wave clearer
+ Very strong late game
+ No mana
+ Great teamfighter
+ Highly rewarding

Cons:
- Needs kills to be effective
- Isn't a tank, can't jump in 1v5 like she's Malphite
- Melee mage
- Gets focused a lot

In my opinion, pretty standard AP Carry runes. The AP gives some nice damage, while Magic Resist helps you in mid almost always to survive easily and the Magic Penetration makes sure people who build Magic Resist won't take too much less damage from you.

Pretty standard AP Carry masteries.

Ability Power, Cooldown Reduction and Magic Penetration in Offense.
Health Regen, Health and Magic Resist in Defense.
Nothing in Utility, since Katarina doesn't need this tree. She doesn't have any mana and isn't a support either.

Probably everyone thought at the beginning of this build while they were looking at the items: Where is the Hextech Revolver?

Well, Katarina doesn't need it. In my opinion, the Deathfire Grasp is a lot better early game on Katarina. She will deal tons of damage when you are doing Death Lotus and you use your active on Deathfire Grasp.

Other items are pretty obvious in my opinion. The Abyssical Scepter and the Zhonya's Hourglass make it easier for you to survive teamfights, since you get focused a lot as Katarina. The Liandry's Torment is great for the end game, since you will deal too much damage for the enemy team to even react to it, and best of all, when you get a kill or assist, you can just Shunpo to the next target and so on!

I don't start with Doran's Ring, because Katarina can get some crazy damage on her early game. This is why she needs to have Health Pots in the beginning.

Q: Bouncing Blades
W: Sinister Steel
E: Shunpo
R: Death Lotus

R > Q > W > E

To jump into fights: Q -> E -> W -> R
And then continue this order the whole game.

Try to get Creep Score by doing this order:

Q -> W
If you really want to farm a little bit more without auto-attacking, use Shunpo, but be sure you won't be ganked or you'll probably be dead.

You should get some wards in your inventory to:

- Put in your lane to Shunpo away from possible ganks
- Get over obstacles by putting the ward over the wall and Shunpo towards it

Get your teammates to be near to you over a wall when you are running away, since you could just Shunpo over the wall to get away from fights, and maybe bait some people to flash as well and melt their face down.

Hope you learned something from this guide about Katarina: The Sinister Blade! Hope you can get some nice scores for Katarina. It worked for me, so let's hope it worked for you too!
