There were speaked about Katarina's playstyle so much.

I'll tell few tips on how to play Kata:

1. Go midlane.

2. Early game focus on last hitting creeps, be carefull harassing/ganking enemies - you need to be sure to run away after your combo if you dont kill enemy with it (your spells are strong, have a not long cooldown and absolutely free! but after you use them you are open for attack and dont have any escape). It is a hard phase of the game don't afraid if it seems that your early game lasts so long. After you get make and wait for your 1st or mb 2nd doublekill or mb tripplekill)). Here starts your mid game...

3. In teamfights NEVER initiate. In perfect situation be last or 1 before last who go into the battle. The focus is that your opponents loose you from their attention and that is the perfect moment to do your USUAL combo (if some1 doesn't know Q-W-E-R))(I prefer W-E-Q-R) And you will be happy. Do not forget that when you kill or assist your cooldowns reduce by 15 sec
so your Q, E and probably W spell will renew instantly and your ulti will instantly renew after tripplekill. That passive is the main Katarina's weapon and every adequate Kata's build is based on it.

4. If the game is going long you can add:

- - more magic penetration
- - more magic resist
- - armor
- - for chasing (if enemies run away so successfully)
