START OF THE GAME:

Try to harass as much as you can with your Q. That will hopefully get them to miss a couple CS and can get you ahead. Don't forget to use your W when you get lvl 2 to help you CS if you are getting harassed since it has some range. Once you get lvl 4 is when you start to do damage. Make sure you E, Q, auto-attack, W. That will do major damage and push your opponent out of lane.

MID GAME:

You are going to need to start roaming a bit to get yourself some kills. Push your lane to the tower and go. By this time, you have your R key. When going in on an opponent, make sure you E, W, R, then Q when you can. If you can't get the Q in there, don't worry to much because you will probably get the kill anyways. Repeat this process to help out your teammates and get you fed.

LATE GAME:

You need to have good positioning late game because they will be looking to DPS you down as fast a possible so this is where ZHONYAS HOURGLASS works the best. When you get into a team fight, you wait for either the top/jungle/support, to engage, E to someone in the middle of them all and just press your R key and watch the kills rack up. If you see your getting low hp fast, use ZHONYAS! And remember when you get a kill or an assist, your abilities had cooldown reducution so look and see if they are up to be used again!

• When Katarina gets a kill/assist, her spells' cooldown reduces.
• You can E to a teammate/minion/ward to get out of a bad situation.
• She can be a very good game changer.

Please comment below if you need anything else explained or have any questions/critism! I will try to make more guides depending how well this one works! Thanks!
