I play 21 points on Offensive because i want to get the AP,CDR and Magic Penetration that it gives. I play 5 points on Defense for the magic resist and the armor so i won't be able to do die so easily. And the final 4 points i play them on the Utility tree for the reduced time spent dead and to improve my flash spell.

I get the magic penetration runes because both her shunpo and bouncing blades benefits from it. I get the health runes so i can have a bit more health and so i can survive a bit more. And finally i get the ability power runes because Katarina is hero that plays with ability power and she needs as much as she can get.

Flash: For me flash is the best summoner spell for Katarina because along with shumpo it's like having two flashes. Imagine chasing a fleeing enemy champion that is not in the range of your shunpo. You simply flash closer to him and then boom you kill him with shunpo.

Ignite: I get ignite because it helps me with the damage. And whenever it is on cooldown i get 10 more ability power and damage.

Exhaust: Exhaust is a really nice spell for fleeing or slowing an enemy champion. If the enemy champion doesn't got stun you get to him with shunpo then you put exhaust on him and you tear him apart with your ultimate.It is good for fleeing too.

Ghost: Ghost is another good summoner spell for katarina. You can use with the same way as you could use flash and shunpo while chasing a fleeing enemy champion or when you are trying to run away to save yourself.

Starting Items:

I am getting the tome because i want to have a bit more boost in ability power along with my runes so i can do more damage and i get the potion for the extra survivability.



Core Items:

Hextech revolver is a core item because of the ability power and the spell that gives. Using your ultimate or other abilities you will get some life back because of the spell vamp.

Rylais is a very good item because it gives you more survivability with the +500 health that it gives you. Plus the unique passive that it got which makes your abilities to slow then target when they hit him.


Damage Items:

This are the main damage items for Katarina.The magic penetration from Sorcerers Shoes will allow to do more damage to the enemy champions. The AP and the unique passive of the Deathcap will give a huge boost to your Ap.And the void staff along with the magic penetration and the Ap will do the same.


If things are going well:

If things are going well and you see that you will be able to get pass 4 stacks you should get Soulstealer. For each you will earn extra ability and at 20 stacks you will get CDR that's pretty cool.


Against Stun and CCs:

In most of the fights you will need to use your ultimate which will get you to jump in the heart of the fight. I get the Mercury Treads so the CC spells will last shorter and i won't die so fast. And then i get the Hourglass for the extra AP that it gives plus that when i see that i am getting attacked during the teamfights i will use it so i won't get any damage at all and my team will be able to safe me.
