I am just a ordinary player that loves Katarina. She is my main, I played a huge amount of games with her and I think she is a extremely fun champion to play. And when used well, she is the best APC there is at this date.
To use her well you need to realise a few things, understand her weak spots and exploit her strong. Katarina is all about positioning, thinking ahead and quick reactions.
Why am I making this guide?
Because I see alot of Katarina's making mistakes, doing things they couldve done better if they would only have known more about how to play with Katarina. When I don't play mid, and I see someone else playing Katarina, I can never help it to keep giving advice to our allied Katarina, advice that is mostly appreciated.
After reading this guide, you will be ready to stomp mid's with Katarina, and go sky-high in ELO.
I apologize for any bad grammar/spelling if there is any, please comment me to it and I'll fix it. English is not my native language although I do get it in school.
AND DON'T FORGET! GOTTA KAT 'EM ALL!
Huge burst damage
High mobility because of
Good harass (with a pretty long range)
Scales well on AP, and even on the AD from a
Pushes lane quickly
Very fun champion to play
Cc hits her hard
Guide released, videos/screenshots incomplete.
Made a early, mid and late game chapter. Providing more in-depth information.
Fixed some messing up at Fiddlesticks counter information.
MasteriesMy masteries are simple, they give Katarina extra damage and extra HP (so she has more time to combo/snowball). The only thing you can possibly argue about are the points into the armor or the magic resist tree.
If you are playing ranked games, and you see they have a AD mid you obviously just switch to the armor masteries, and if you see they have a AP mid you take the magic resist masteries. It is simple as that.
Are there alternatives, yes there are. Some people like to make Katarina very tanky, then you could consider a 9/21/0. But I do not advice that and the guide is not about that.
And someone messaged me about a 9/0/21 build. The answer is NO, just NO, never ever, ever, ever.
Magic pen for getting extra damage, usefull in early and lategame. Best marks for Katarina, never change. UNLESS: you are extremely bad at last hitting, you could swap them for Attack Damage marks making last hitting more easy, but I do not advice that (The abilities do scale on the AD though).
Health per level, I pick those because those will give you a little bit of extra time in the late game team fights, and are always usefull. If you have alot of rune pages you could also use a same page as this, but then with flat armor runes. This would be good to stomp a AD mid early game. But will fall off in the end-game.
Same thing as the seals, this damage is the best because you scale while leveling in lane, and it gives about 33AP endgame with your Rabadons, and that damage can make the difference between getting a kill that lets you snowball, or just dying before you can finish that first champion for your passive to proc. You could swap these for flat magic resist tho, if you are a against a heavy burst mid, I advice these runes against a Kassadin or LeBlanc matchup. But not really against any other champion.
Always flat AP, never something else. Why flat AP? If you have to ask that, don't play Katarina anymore.
Summoner SpellsAdvised spells:
Always flash, allows you to close a gap to get a kill, or possibly start a snowball.
Or lets you escape from a bad situation.
Flash has alot of uses, ALWAYS TAKE THIS, ALWAYS!
Just take this and believe me.
Well maybe..... For barrier/heal baits I guess... And if you do decide to take this, although I do not advice that, if you use those, they will NOT stop the channel on your ult. So yes you can use them to ult longer without dieing.
No way, just no.
Well if you are a troll... This is a excellent summoner spell.
Possibly on cc heavy teams, but it does not make up for losing ignite or flash.
Your shunpo is a gap closer, your W gives you a speed boost, you don't need exhaust to chase people. Might be usefull in situations against a AD champion. But ignite is still more usefull then.
Ehhhmmmm yeh right.
Does anyone even play Dominion?
Flash is just way better, and to replace ignite with this... allows you to reposition very well tho, and escape bad situations but you need the flash and ignite.
Removed by Riot because this spell was way to OP!
Doesn't exist, are you drunk or something?
You have to die to use this, NO. If you play right you shouldn't die alot. In teamfights at your nexus tho this spell can win the game for you, if you feel confident on your Katarina plays, you can take this for the fun.
Do you jungle? Nope, so take it? Nope?
Are you against Heimerdinger? Yes? Consider it then, and take the mastery for the gold then.
Are you serious? Taking smite against Heimerdinger why? Well Heimer can't do anything if you have that, it gives alot of gold in laning phase. It is considerable.
I'm trying to wipe this awefull Spell from my memory, stop reminding me of it.
Well, more farm, more lane control, global control, strong ganks. Considerable to use this instead of flash/ignite. But I don't advice it.
All by all, take and . You can consider //
This is what makes Katarina such a epic teamfighter, what does it do? If you get a kill or assist your Q/W/E will be back up INSTANTLY, and you well get -10 seconds cooldown on your ultimate. When you are level 18 maxed built your ult will be up again after a triple/quadra kill/assists/combined.
Also allows you to shunpo to safety after getting a kill or assist, under a turret back out of the turret range for example. You can use this on alot of things, Jarvans standards, wards, minions, Shaco boxes and Teemo Mushrooms.
Q: Bouncing Blade
Your harassing ability. Your farming ability. Your main damage ability. Your core ability.
Use this to harass your opponent. You can do this by hitting them directly or by using minions. After every hit it does it will do 10% less damage, meaning using this directly on a champion does more damage as casting it via a minion.
Or use to farm, you can use this first to damage and mark 5 minions. And then use your W for damage and to detonate the mark dealing additional damage. In a average game around level 8-10 you can use this combo to kill the mage minions at least, and when around level 12 you can instantly farm 5 minions. Making you able to farm extremely fast. And when still laning late game also go for the extra farm on the wraiths or wolf camp.
Because this works nice with your W you can use it for damage. Or as Phreak would say it: TONS OF DAMAGE.
This is the ability you max first, because it is your core ability.
W: Sinister Steel
You can use this to proc your Q, get away from someone by using the little speed boost it gives you. Or you can use to to farm a minion wave or to quickly poke a enemy champion.
Note that the speed boost only procs when it hits a enemy champion.
Does a bit of damage, can proc your Q, is a gap closer, initiation ability and a escape. Combine this with wards and you are extremely hard to gank.
But one of the biggest powers it offers (what alot of people underestimate) is that it gives a whopping 15% damage reduction for 3 seconds. And you only need 2 seconds to channel your ult. This makes your E even stronger.
R: Death Lotus
This is what makes Katarina, it's one of the best ults ingame. When fully build AP glasscannon it does around 2000 damage, PER TARGET, and it strikes 3 targets at once. Meaning 6000 damage in 2 seconds, combine this with some spellvamp and you are ready to go rambo.
Skill OrderYou max because it is her most usefull ability. And you take it first to have a early harassing ability or damage the minions. It also scales the most on your AP.
At level 2 you have a choice, do you want more damage and can you get close enough to your enemy to hit your ? Then take it, but mind the enemy jungler, if it is a jungler that can gank you before you hit level 3 it might be a grave mistake, possibly giving first blood to them. Or making you burn your .
You can also just take your . It procs the passive and you can auto attack once after you shunpoed. Allowing some decent damage early game. But mind that your cooldown is high early game, and you might spill it and get ganked, so be carefull in using it. You have to be aware where the enemy jungler is before you use it.
Just take a level in this when you can, if I have to explain why you have to do that. Stop playing league of Legends.
Movement speed is important on any champion. Just take them and build in when possible.
Not to expensive, can build in one of the two items which you will always want one of at least. Gives damage, and great substain in-lane. Just take this unless very fed. But after rushing Rabadons taking this would be the best anyway.
DAMAGE! Pure damage, you want this, adds so much damage to the item and is a item that can NEVER be let out of the build. In no situation.
Choice in boots:
This should be your basic choice, getting movement speed and Magic Pen. Good boots just take them in normal situations.
Take this in a situation where you are getting owned by a AP champion OR if the enemy has alot of cc OR a spamable stun ability (taric for example, you want mercs if they have him on their team)
No. Just no.
When you are epicly fed and want to gank alot, this might work, but I do not advice it. Other boots are just better.
No. The movement speed and passive won't do alot for you. Just don't take them.
CDR is pretty nice in-lane for harrasment, but these boots suck late game, as in teamfights you want to kill someone for your cooldowns not wait for them to come back up. So NO, never take these.
Not advised although it's cheap for the movement speed and it might be usefull against a AD mid like Zed or Talon. But I do not advise these boots.
I'm fed like hell, I don't need better upgraded boots. Maybe... until you miss that little movement speed to escape or catch up with someone for your coveted Pentakill. You'll regret that then... If you don't have upgraded your boots at least after the revolver and deathcap, then you are doing something wrong. You need to have them upgraded by then.
Items I advice:
OR This gives substain and damage, taking the more expensive will also allow you to use the item ability, for extra damage and a slow. Which is walys usefull. And the is usefull if you have a AP top or jungle. And it is cheaper, gives more spellvamp and more Ability Power. This item is my first choice, and possibly ask your support/jungle to get this item later, then sell it for the .
This item or/and is also incredibly usefull, the reason why will be explained later.
Always against a MR stacking team (people with and .
You do not have mana, some of the stats are wasted on you. THO the passive is great! If they have a or any other champion with some insane healing () So this item is completly situational and wasted when there ain't a swain/mundo on the enemy team.
ALWAYS BUILD with this. The rylias procs the extra Liandrys damage. And together they give nice health and good AP. If you get bursted down to much, or just want some slow to assist your team. Take these 2 items, they work great together and are good on Katarina.
Great item, if you get knocked to 0 HP you have a new chance to unleash your combo's especially if your team got a kill your CD's are back up, and you can burst someone else possibly starting a killing spray and snowballing and eventually winning the teamfights. Unless extremely fed this item is ALWAYS a good choice. Building this is okay after core.
If you learn when to activate this, this is a great item. And together with it will be almost impossible to lose teamfights. If you use this correctly you will have 3 full combo times. Let me explain how: You go in with full burst Q+E+W combo. Decide if you want to ult or not, don't do it if there will be alot of CC coming your way. If you see the CC and bursts coming your way, activate the , also when you ult and you take on person down, and won't have enough damage in your ult left activate it to, so you have some time to think about your next step, get ready to target the next target and use the combo this way E+Q+W, always wait about 0,2-0,3 seconds so the Q hits and you can detonate the mark with your W, still didn't win the teamfight? Five of them are alive but low? And your team is losing? You drop to 0 hp? Guardian Angel activates, now think quickly look at what enemy is the lowest HP and a sure kill. And determine who you want to get after that, then think quickly use E+Q+W then if you kill do E+Q+W again. And get that penta :), don't forget that after 3/4 kills you will have your ultimate back.
If they have 2 or more AP champions, or this mean keeps bursting you down, take this, the AP is good, and so is the MR and even the passive helps you, overall a good item.
Items I don't advice but are valiable:
: You don't want to focus on only one target, although this item gives great AP and then passive ain't bad. I do not advise this. The passive works against 1 target while you have 3 AOE spells. Other items are just better picks, but if you want to burst down a target combo this with a Lich Bane and a Hextech Gunblade and you'll burst harder as a on steroids.
Well it gives nice AP and you can help out your teammates with this, but it ain't really advised as there are just better items for Katarina, when you have taken the Kage's tho, this might be the only other option besides selling it.
Only against a team with 5 AD, you should get this item, the reason is obvious, against a 5 player AD team you are god with this item.
Don't take these:
You don't even have mana dummy, this item is a waste.
Again you don't have mana, passive won't do anything for you. Maybe when the enemy team has 3-5 AP champions you can use the AP, CDR and the magic resist. But I do not advise that.
This item just has bad stats, and Katarina clears waves very quickly so don't get this for the passive to. So this item is a NO.
Gives good stats, but she just can't utilize it fully, and it would be a waste of money for the slow part, critical % and attack speed.
You are not a tank, you will not be a tank, and you won't be a off-tank. NO! NO! NO!
This items stats are bad, you don't really need the passive, only a Nunu is good with this. So no.
Thinking aheadThis might be the most important part of this hole guide, thinking about your next steps. This involves three important points:
This is the most important of the three points. You need to position yourself right, you need to be able to jump in the fight and start wreaking havoc among the enemy champions. Or to retreat yourself when things go bad. But the most important thing is that the enemy team does not spot you. You are a assassin if they see you, they will be more cautious and will react faster when you jump in. You should always try to have the element of surprise. And because they didn't see you, they will also use valuable skills that can be used to stop you.
Try to be aware where your enemy warded, or take a purple ward with you, so you can camp a bush from where you want to initiate in a fight. So they can't see you coming.
You have to be aware what the enemy team can do to stop you. In almost every game you will be the top priority target. That is why you have to position well. If there is a Soraka against you, the chance that the silence will be saved specially for you is great. Because it can instantly cut off a Katarina ult and prevent snowballs. So what to do about this?
Well if you don't show your face to much as explained above, they won't be expecting a sudden jump in. So if you watch carefully and see Soraka blow her silence then you can go in for some swift punishment and make them regret that action.
Does that mean I always have to wait? Well no, in the case of Soraka she is easy to combo down and will most likely not have enough time to react if you burst her down first. But in cases of lets say Cho'Gath you have far more problems. You need experience with Katarina to know when you should dive in, to enable yourself for a longer ult time, even if it only buys you a half second.
A half second... yes! What alot of people don't understand is the insane power of Katarina's ult. If you are full builded and the enemy didnt stack MR you will do around 2000 damage per target (max 3 targets) with your ultimate. Your ultimate channels for 2 seconds. So that means 0,5 seconds equal 500 damage! And that times 3! That 500 damage can easly make the difference between starting a snowball or just dieing and your team losing a important teamfight over baron, or maybe even of your Nexus.
You need to know when to jump in. There is only a short time between going in to early and getting blown up, or getting to late when the teamfight is already lost. Together with the two above points you need to learn when your moment is to attack. Go when you think you should and if it turns out it didn't work out. Think why it didn't work out and adjust your strategy on it, so that a next time you will do it correct.
CountersI have listed all champions I deem valiable in mid against Katarina, the rating will explain how the lane is made for evenly skilled champions against each other, but after reading this guide you will have the knowledge to be a top-notch Katarina. One worthy if Diamond Elo. So you would be able to outskill anyone and win from champions the odds would say you would lose.
1-3/10: If you lose this stop playing Katarina, sticking with Soraka might be your thing then.
4-5/10: Easy setup, but watch out not to get cocky, you might be outskilled and with some ganks the opponent can start winning.
6/10: Skill lane should be even, depends on the skill of the mid champions and the jungle ganks.
7-8/10: You are in the disadvantage the other champions counter you, but with some skill and ganks you can win.
9-10/10 You should always look if you have a top you can swap then. If you can't be very careful and just farm, don't let the enemy kill you and look if he gets cocky and you might be able to kill him. Just try not to feed and survive. Dying loses you time, exp and cs. So just be careful. This lane is annoying but remember that if you get true this by staying calm you will still be useful in teamfights later.
5/10 When you dodge the skillshots and wait till she wastes Q before you jump to her, you will win the lane and outfarm her. Killing her proves to be difficult because her taunt breaks your ult and she has 3 flashes with her ult.
6/10 From level 6 she can burst you down more easly, make sure you don't let her do that twice for free, when you are both around the same HP just give her a Q+E+W combo so you trade evenly. Upon hitting level 6 just ult her, even when you cannot kill, this way she will have lower hp, won't just jump to you and give you a easier time to farm.
4/10 Don't let her land her Q and win, don't get egg baited and you win. She's slow and low HP exactly what katarina likes, this is a easy lane but don't get cocky.
8/10 Hard lane, you can outburst her if she doesn't ult, but her stuns are dangerous. Play safe and farm alot, ask for a gank from jungle and you might be able to win lane.
7/10 People underestimate this champion, if you ult he will be able to hit everything. Also when you shunpo to him you are a easy target, and when he stuns you he will burst you to. Make sure to just poke him alot with your Q and don't do reckless Q+E+W combo's. Stay safe, think what you are doing and you will win this.
5/10 Dodge everything she throws at you and you win. Try not to face towards her when you start use your ult. So before you ult, move back a bit your own turret and then she can't stun you with her ult, only slow, and you will continue channeling yours. Easy lane if you stay calm. Mind when you Q+E+W to her she doesn't fully combo you.
9/10 HARD! He's tanky you can't kill him, he farms nice, has substain and has 2 abilities that can cancel your ult. Look if you can swap or go safe on him. And farm from distance. Don't attempt to kill him, you can't.
Kat wants to ult? e
Kat wants to shunpo away? ult
Kat wants to farm? q
Kat wants to poke? w
You want to avoid her at all costs. At this lane-up I advise dodging. You can't win this lane, only be very safe and farm under turret. Only when a very low skill Diana plays against you, you can win. Also in endgame be cautious.
4/10 Easy, dodge her bind and just use your combo and then back off, she can't trade that back to you, and will go OOM (Out Of Mana) and you will win. This lane ain't hard.
7/10 You win the lane, lose the endgame. She's stronger as you lategame, her burst is just to much on you. In-lane just poke her alot and farm, don't let her combo you all the way or sneak up from the back. Never let her run away without a knife in her back.
9/10 Your ult makes his healing less potent, but his silence and fear cancel your ult. He's horrible to lane against, without ganks you shouldn't be able to win this 1v1. He has substain, damage and alot of CC, try to swap top when you are against him.
7/10 He has a strong burst, just be carefull on that, his playfull trickster causes your ult to be unable to work, and his ult cancels yours. Be carefull on this little Yordle.
6-10/10 You can't kill him, but he also can't kill you without ganks. Just don't get caught in his ult (allows jungler to attack you). And just outfarm, he ain't really usefull late game except for his ulti and shield.
3/10 He has some nice poke, but you just outburst him, the CD on his Parley (Q) is lower as your combo, so make sure to stay out of his Q range when your Q+E+W ain't up, and you will win this lane.
7/10 Good Gragas' win from you, but in general you will outfarm and most likely outharras him, just dodge those Q's and don't get caught in a nice Gragas' ultimate and you will win this.
3/10 Just don't jump to him when he's in his turrets. Don't get poked to much and don't let him land his E (grenade) mind that his E stuns when its right in your face. And he can do that when you ult. Be mindfull on this little guy and you can win from him, although keeping up farm might be hard. Try to kill his turrets with your Q and consider taking (explained earlier)
?/10 I have to confess I never in around 600 AP mid games played against a Karma. I know how she works but I don't think she would be hard. But I can't be sure. Be carefull and don't get baited by her low HP shield. Ill get a rating for her when she's reworked.
2/10 Easy win, dodge his Q and run out of his Defile (E) after you used your combo. And then this is a easy win. Don't stay around when he dies to. He also has nothing to escape.
10/10 Your ultimate counter... He is awefull, he's strong, he has a silence, he outbursts you. He's only a bad farmer, try to stay behind and try to get ahead with the help from your jungle pre-6. Post-6 you have a problem. Stay at turret and try to farm some minions and possibly take Wraiths. He will own you unless he's a total noob.
5/10 (why 5 and not 6, they're the same champs) You read this guide so you have a advantage, after reading this you know how Katarina works, If your AP (so your burst) is bigger feel free to just burst her, but try to get higher farm. This also can only occure in normals.
6/10 Pretty even, if you get stunned she can do some nice damage. Try to be carefull, you can outfarm her, and outburst her, to help you dodge her ability you can think about maxing this time for the movement speed.
8/10 Hard lane, she has nice bursts, a possible silence and a stun. Be carefull on her, try to farm, get some ganks from jungle and you can win this.
6/10 When you dodge things you win, if she binds you, you have a problem. The good part is, normally Lux's aren't fast enough to do the bind+Q+ult combo BEFORE you are able to to your allied minion to dodge the ult. That's a pro. Also don't let her autoattack you everytime pre-3 (full combo)
8/10 He ults you when you ult, he has a nice farming ability and a silence. Be carefull on this guy. But you can win if you use what you know.
8/10 Joke right? AP Yi ain't valiable..... Well yes he is, his Q does some decent damage and his W gives him insane substain, don't underestimate this guy, just farm more as him (which will be hard), and you will be more usefull late game, because he can only rambo with his Q lategame, hope for a kill so he can Q again because of his ultimate.
7/10 Hard matchup, his shield is hard to break and he pushes real hard, you can win from him tho, if you try to poke his shield away before you do your Q+E+W, also try to run around him so he can't hit his E cone.
4/10 Dodge her bind and you win this easily. Use your to escape her ult. And this will be a easy win, she can farm hard tho.
3/10 Dodge her spears, don't underestimate her Cougar combo's and you win this. She has some nice substain tho, but your burst and reliable harass is just to much for her. Remember to stay behind minions so she can't ult you well. And keep moving.
6/10 Orianna is strong, but it's a pretty even lane, away from her balls, try to get more farm as her, and your burst is a bit higher, just be carefull on her shield, try to fake comboing her by running towards and throwing your Q and then not to her, she will waste mana then. Don't tank to much autoattacks from her and outfarm her. You win then.
5/10 You outburst him, don't stay in his combo area to long, your passive makes his ult working less good (it makes the spellvamp lower). Don't let him bind you and don't stay after bursting him. Also be careful about his autoattacks.
7/10 Yeh Soraka is hard on you, if she has a fast reaction she will just silence after you Shunpoed and then use a lot of Q's and autoattacks while you run away, she wins trades, out sustains you but she can't do the damage in teamfights that you want from a APC, just outfarm her (which is hard) and harass her with your Q's so she will get OOM from the healing she does to herself. And then you will win.
8/10 He has a silence, his silence/blink range is bigger as your Q, make sure after he did his combo you quickly do a Q+E+W combo on him so he won't completely win the trade. All by all this is a hard lane. But if you stay calm you will win.
6/10 She can land her abilties when you to her, can break your ult. But all by all you win this setup because your burst is stronger, your can be used to dodge her harass. So pretty even, just farm.
8/10 If you get behind, you can't get back, try to keep up, get nice farm and don't let him harass you. If you want to Q+E+W try to let him waste his bind then jump to him and you will win the combo.
4/10 Hard pre-5, after that you will just win because your burst is higher then. He farms hard though and kills turrets fast, don't gank other lanes alot with this matchup.
4/10 She ain't one of the champs that's strong against you, she has some nice combo, but you can win this, remember her ult breaks your ult. Just stay calm.
3/10 Easy, you can easly win from him, dodge his Q then use your combo he won't have time enough to react and take a yellow card. You will win this easily.
2/10 Veigar is more of a end-game steroid. Just dodge his bind ( out of it) and you will easily outharras and even outburst him easily. Don't let him farm so he gets useless late game. A pretty easy lane, if he does get farmed up make sure to get some Magic Resist so he doesn't one-shot you late game.
4/10 Don't get stunned by his slow/stun and you will win from this guy, also away from his slow/stun and from his ult and you will win.
3/10 Dodge his skillshots and you win from this little guy, make sure he wasted his stun before you jump to him. You can outfarm and win from this little guy.
6/10 He is a annoying little grrrr... He outranges you easly with his poke, and when you shunpo to him he can hit his full combo. Play smart on him, and jump to him after he wastes Q+E on farming then this will be a easy win, mind his strong farming and try to deny him.
2/10 Bad Zed is bad, there aren't a lot of good Zed players, and you just outburst him anyway, you don't need a special tactic on him. Just mind his passive when you are low HP.
8/10 Really hard, he counters you a lot, the double bomb out-harasses you, and his ult blocks your ult. You can't kill this guy, just try to farm and be more usefull late game.
4/10 Dodge her bind and she can't combo you, you can even use her plants and seeds to escape because you to them. Her ult cancels yours.
Champion combinationsBest possible combo with Katarina, if he can catch the hole enemy team with his ult, you have time to fully channel your ult and kill at least three of them. This combination with him jungling is AWESOME, I advise this for any duo queuing get a friend to play Amumu jungle and your ELO will skyrocket.
His ults stops all the bad CC coming your way that cancels your ult, really usefull I advise playing with a Blitz.
His Q allows you to pick someone off and his W blocks people from stopping you.
Same story as Amumu his ult allows you time to own the enemy team.
Same story as with Amumu works great.
Pulls people together, works great with your ult!
If he ults to you, you will have a nice shield that works perfect for not getting bursted down.
His stun allows you to catch people or even hole teams. Not as effective as the other ults people have, but he can use it alot more and is very usefull.
Her bind and ult both allow you to pick off people. Good combination.
I explained before what you need to do to be successful in teamfights. Make sure you focus the ADC or APC first. After killing them try to use the support to snowball even further. The ´Thinking Ahead´ explains everything you have to know for the teamfights.
A important thing is that you communicate with your team, so everyone knows what he/she has to do. Who you are focusing and possible points of attention. This can make the difference between winning or losing the game.
Another important thing is, if a teamfight is lost. NEVER FLAME, your team, this will only promote the so called 'throwing' while with Katarina, the game is never over. You can always get that snowball and start coming back. Never give-up. Support your team, try to help them by explaining what went wrong the last time and give the advise, try to do this in a non-forcing way so they won't feel like being lectured.
Early GameEarly game you should focus on farming, not on getting a kill. Also only use your Q to harass early and try not to get damaged by the opponent. When you hit level 3 your Q+E+W combo is up, allowing you to trade with the champion you are against. There are 2 cons to this, 1. you will use your shunpo and be vulnerable, 2. if the other champion can burst you harder you lose the trades.
You are very likely to get ganked early, because Katarina is a high priority target, that needs to be shutdown early or will snowball hard into late game. To avoid dying early try to keep your Shunpo up and not push lanes. Not pushing the lane is pretty hard as your Q and W both are AOE and will quickly destroy a minion wave. If possible always try to just last hit the minions, instead of throwing your for it.
Mid GameMid Game is where you start doing more and more damage. When you are getting behind on the enemy mid laner just Q+E+W to him and start ulting, even if you know you can't kill him, the enemy will take some serious damage and won't be as agressive to you anymore. And because your ult has a low cooldown using it for this is no problem.
Basicly you should keep farming and look for a possible kill. Securing a kill can be done in multiple ways, the enemy overextends and dies to your combos and/or ult. Or he is with low HP and doesn't go back. Be aware that it is very likely you get baited then, that's why you need the element of suprise. If you are sure your Q+E+W+ possible ignite can get you a kill. Then stand away from the enemy champion to a range he feels safe, then suddenly flash towards him then on him, throw your and use your and use your ignite if needed. This might allow you to secure a free kill.
Another thing you can do, if your lane is going pretty good you will eventually clear waves very quickly. Then just push your lane, combo the minions with your skills and then clear your own Wraith camp when your jungler is not farming them. This has 3 advantages, more farm, health back from wraiths and the minions you push will die to turret fire and give the enemy champion less farm.
If small skirmished start or even a baron fight, don't be afraid to participate use the knowledge from the thinking ahead chapter and stay behind till you have a opening to jump in. In mid game Katarina has great damage potential but you have to stay careful, if you get CC'ed you have a problem, as you don't have Zhyonas or Guardian Angel yet.
Late GameYou are finally in the late game, time to shine Kat!
You should always keep farming, don't forget to stack up on wards and get out there. Walk a bit behind your tank and stay out of sight, you are a assassin and you need the element of surprise. In teamfights some guides say you should just suicide on the enemy ADC or APC, they say you do AOE damage so that you do a lot more then. But that is not true. The impact of killing a enemy champion/or getting killed yourself is huge late game. Respawn times are high and you will lose alot of XP and CS by dying. You should try and wait for the perfect moment, to kill people, make your team win the team fight and most importantly to a moment that you will not die when you attack.
Another thing that is important that when you secure a kill it might be wise to give it to your teammates, if you are already fed and you take all the kills your team will stay behind. If you ever get shutdown then your team might be unable to fend off the remaining enemy champions. As Katarina it is harder to carry as when you are e.g. Veigar, you need your teammates to help you.
Focus on objectives!
A lot of people make this mistake when they get fed on Katarina, and they just want to go for kills. But that is a awe full plan, the enemy team will get more prepared for you get more Magic Resist and more health, effectively countering you. You should shift your focus to objectives instead of chasing down that Ezreal for one more kill. A turret is worth 150×5=750 gold, that is equal to 2.5 champion kills!
Don't take all the CS!
If you have done it well you should get farm really quickly, and kill 5 minions with your farming combo, but remember that your teammates are important to, it might be smarter to give your ADC the farmer as taking it yourself.
Wards, all you have to knowComing in the future.
