Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Getting Your First Kill
So most of you know Katarina is ****ing awesome
Take mid early game, **** the vlad that is arguing with you, and just go mid.
Harass with Shunpo/Bouncing blade until level 5, Once they are half - low HP, stay at the back of the line and use the most badass trick in the game, flash and Shunpo to them, ignite, bouncing blade. If you are good they will die, if you are bad go play Warwick.
As they are raging in chat as you just "DOUBLE SHUNPO'D" Go back and get your Sorcerer's Shoes.
Now That People Know Who The **** You Are
Okay, now that you have this Flash/Shunpo Trick down, and your ult, the only thing stopping you is that your bad.
Anyways now, Go gank lanes by doing Shunpo + Ult and then Blading them.
Once you get your gunblade it's GG
Katarina late game is very complicated...
In teamfights do this
Make sure you KS as much as possible with your Shunpo so that your Ult has it's CD reduced
Pros / Cons
Helps team Kills
Squishy if focused
Your team will get mad at you for KSing
