Introduction

If you've ever played a really good game as Katarina, you already know something about her: she loves to snowball. Now, I'm not saying she's the snowballing god (that position is currently controlled by

Because Katarina is cunning. She preys on mistakes, and is incredibly deadly in the right hands.
This is a guide to playing full AP Katarina. Katarina has strong poke, doesn't have a mana pool, and is a both a great contributor to teamfights and a fantastic janitor and chaser. Her only real issues are being squishy and easily countered in Ranked/Draft, but she can still overcome almost any confrontation when used properly.

Katarina's squishiness, but I personally find that missing out on that little extra AP and MPen is more detrimental.
The Utility tree is pretty much useless to you, especially since you have no mana pool. I guess it could be possible to run something like 23/0/7 putting points into

If you still have doubt, here's the reason why:

This is where Katarina's actual strength lies. It almost forces you to snowball after getting a kill, and can work wonders in teamfights. Yes, I'm kind of over-exaggerating here, but just don't underestimate the power of your passive.


Your basic ability for poking and picking up farm. This is especially helpful for both because 1. You are melee, 2. You have no mana, and 3. You are melee. It is a very strong poking tool, and if you can whittle your opponents health bar down enough, you'll most likely be able to secure a kill thanks to its mark. It is also made to work nicely with the rest of her kit, specifically Sinister Steel, since you can easily proc all marked enemies in an area.
Now, this ability is great. It has super low CD from the start, deals a lot of damage in an area, and gives you an MS boost after hitting an enemy champion with it? Yes please. This in conjuction with



Probably Katarina's signature ability. Blinks you behind your target, friend or foe (or inanimate object. More info in the Strategy chapter) and both deals damage and grants damage reduction. This lets you get up close and personal without too much issue, and is integral to setting up combos with the rest of your kit. Efficient use of

This ability really gives


Only problem - it's channeled. Most forms of hard CC should shut this down, and your license as a squishy AP assassin still hasn't been revoked. Good timing and positioning with this is essential to pull it off successfully.

A must-have on Katarina. This is a very strong early game item, making you tankier and noticeably stronger. You should be able to take and deal a bit more abuse with your laning opponent. |

Hoooo, buddy. This one is worth talking about. Personally, I dislike snowball items, but on Katarina it seems like a perfect fit! Right? Well, not really. Even with those fancy pants items of yours, you can still be killed with relative ease if focused, meaning that ![]() |

There's a lot of debate on whether or not you should get this item on Katarina. Your pokes and your ultimate get really strong and you become the bane of tanks, but you sacrifice some burst for it and you don't get it's full effect. I would still consider buying this, but only if you bought a ![]() |

Unless your enemies are complete idiots, someone, some point in the game, is going to build more MRes then you can penetrate. At this point, you're going to want to grab a ![]() ![]() ![]() |
Survivability

Get this if you're doing well. If you've sufficiently shut down the enemy enough, grabbing a ![]() ![]() |
![]() |
Get this if you know how to use it, or want even more strength. The slow is good since you have zero CC, and it works really nicely with your ultimate and chasing ability, but this isn't the best survivability item overall. However, if you've decided to purchase ![]() ![]() |

Get this if you don't know what to get. It is the most cost efficient source of health in the game, makes you super tanky, gives you regen...what's not to like? |

Here are the exact numbers. Remember that

Flat penetration is applied last (not MRes reduction), so that shouldn't affect these numbers at all. Also, remember that while a





Once you've entered your lane, you're going to want to focus on farming and poking. Katarina's Pre-6 strength is not strong enough to exchange efficiently without the right matchup. You have just enough burst to take on a sufficiently poked-down enemy, but that's about it.
Farming seems simple at a glance, but has its difficulties. You'll want to try to stay out range of your opponent, but the main issue is that you are melee. Thankfully, since you lack a mana pool and it has relatively low CD, you can use your

When you reach level 6, you become super stronk. Not invincible by any means, but strong regardless. CC is still an issue for you, so timing is important with your ultimate. Learning when and when not to jump on the enemy is key to your success, especially in the early game.
Your basic laning combo is Q-E-W, which I refer to as a "hard poke".
Your kill combo is Q-E-R-W. This ensures they stay in range of your ult for the maximum duration of it and
As you transition into the mid-game and start getting into teamfights, your value will rapidly increase. Don't get too involved at the start, your strength as a janitor is amazing thanks to

Also, in this image, whats great about putting that pink ward there is:
- It will detect enemy wards, giving you AND the jungler a great blind spot.
- You don't have to teleport to a tower/minion, making you substantially less noticeable.
- You have an escape route with

Oh, by the way, if you didn't already know, Katarina can use her

(Very nearly finished! It has all the real big counters you need to know, so you should be fine. I am a little busy on another guide and apologize for not fully completing this section.)
A recurring theme in many of these matchups is the important part of Katarina's playstyle:
One thing to note about Katarina is that most of even the hard matchups can be easily countered if the summoners behind them are incompetent. For the purposes of consistency, we'll be assuming that the opposite is true.
- Always keep an eye on her passive,

- Outsustaining and outfarming her is key. Farm under tower if you must.
- Make sure you have a good escape for her combo. Buy a ward if you can.
- Ask for a lane swap, you just got counterpicked.
- Farm under tower, poking is useless.
- Coordinate with jungler to shut him down while he's still weak.
- He only has one ability that outranges your poke,

- If you can poke him hard enough, he will be forced to use his

- If he doesn't have his


- Start: Boots + 3 Pots, unless you're sure you can dodge her

- Play defensively in the early game and try to out-farm her, remember that she's melee too.
- Your harass is technically superior since it's targeted. Dodge her Q's and waste her mana.
- Save your

- Your pokes JUST outrange his. You can also target the enemy minions to poke him.

- Try and shut him down early on. Once he hits level 6, killing him will be considerably harder.
- If he wastes his


- Play passive, poke her down. Her Sigil of Silence outranges you, so be wary.
- She's highly mobile, try and stick near to your tower if you can, it'll save you a lot of grief.

I really do recommend jhoijhoi's manual, Making a Guide, for new Mobafire users.
I also recommend Laggermeister's Ten Commandments of Writing a Guide, as it is equally as useful. Hell, even moreso.
Special thanks to Stanley Kirk Burrell for wearing parachute pants.
Anyways, thanks for reading my guide. Again, rate and comment, give me your hugs and slaps. I'm always open to criticism, so give me a holler!
