Hello guys,
I want to show you in this guide my guide about Katarina.
This is my first guide i m doing so pls leave constructive comments down below!

My name is IDonutEatU in League of Legends and i m Playing in Gold 5, which maybe doesnt sounds very good but i m not playing rankeds that often.
I m Playing since Season 2 Ending so I know many things about League of Legends and also about Katarina.
My Main Champion is still Lee Sin because if u master him he is so freaking strong and cool 2 play but i know how to play Kata too.

Pros: - High Mobility
- High Damage
- Resets When killing/assisting
- Outplay Potential
- High Skillcapped
- Strong Mid/Late Game

Cons: - Useless if Behind
- Weak if there is many CC
- Weak Laning phase

Voracity (Passive) - Every time you get a kill or assists,
Katarina's cooldowns are reduced by 15 seconds.

♥ Your and instantly refresh on kills / assists
♥ Helps you diving turrets, you can in, burst him, and out again
♥ Teamfights give a lot of resets, thus more damage. Be patient!

Bouncing Blades - Katarina throws her dagger that bounces to the 4
closest enemies, dealing 60/85/110/135/160 (+45% AP) magic damage and 10% less damage per bounce. Any spell or attack
consumes the mark dealing 15/30/45/60/75 (+15% AP) magic damage.
Cooldown: 10/9.5/9/8.5/8
RANGE: 675

♥ Multitarget farming and harassing ability!
♥ Also bounces to stealth enemies!
♥ Usually your first ability to use in combos

Sinister Steel - Katarina spins around, dealing 40/80/120/160/200
(+25% AP and +60% AD) magic damage. When you hit an
enemy, Katarina gains 15/20/25/20/35% movementspeed for 1 second.
Cooldown: 4/4/4/4/4
RANGE: 375 (50 less than Urgot autoattack range)

♥ Short cooldown, mediocre AoE damage.
♥ Great skill for detonating Bouncing Blades marks.
♥ Movementspeedbuff for running away or catching up

Shunpo - Katarina jumps to her target, if it's an enemy, she deals 60/85/110/135/160 (+40% AP) magic damage to it. After using Shunpo, Katarina gains 15% damage reduction for 1.5 seconds.
Cooldown: 12/10.5/9/7.5/6
RANGE: 700

♥ Ability to jump into or out of a fight.
♥ Great for chasing, ganking and escaping a gank.
♥ Can be used to jump over walls.
♥ Can be used to reduce a turret's hit.
♥ Can be used to juke a skillshot e.g

Death Lotus - Katarina rapidly spins in place and channels for 2.5 seconds, throwing a barrage of up to 30 daggers at the closest 3 enemy champions within range. Each dagger deals magic damage and applies Griveous Wounds for 3 seconds, reducing regeneration and incoming healing by 50%.
Cooldown: 12/10.5/9/7.5/6
RANGE: 700
Magic Damage per dagger: 35 / 55 / 75 (+ 25% AP) (+ 37.5% bonus AD)
Maximum Damage to each enemy: 350 / 550 / 750 (+ 250% AP) (+ 375% bonus AD)

♥ Great teamfight ultimate.
♥ Can damage invisable targets.
♥ Can be used to harass in lane.
♥ Can be used to check for stealth (Yeah **** you Teemo).
♥ Can be cancelled by hard CC.
♥ You can't move while using your ult.

Her Masteries shall be 21/8/1 Like i Play

1 Butcher 2 Block 1 Scout
4 Sorcery 2 Recovery

1 Feast 1 Unyielding
3 Mental Force 3 Veteran's Scars

1 Arcanery master
3 Executioner

3 Archmage
1 Dangerous Game

2 Devastating Strikes
1 Arcane Blade

1 Havoc

This shall say everything! Maybe u Ask why i use Scout? I Take "Scout" Because You need dat Trinket Range from escaping or maybe from engaging so its pretty nice to increase your trinked cast range right? :D

Take In Marks: "Greater Mark of Magic Penetration" because u will deal much more dmg than with more ap so its pretty usefull

In Seals u Take " Greater Seal of Healt" Because its pretty Nice to Have early hp!

In your glyph you should take " Greater Glyph of Magic Resistance" so u will dominate ur mid lane

in Quintessences Take: " Greater Quintessence of Ability Power" Cause u acctually need some Ability Power right? :D

U can choose between: Ignite and Flash or Between Teleport or Flash.
Take ignite if u want to dominate ur lane and Take tp to f**k the other lanes with a surprising Teleport ( If there is Teemo take tp to f**k him up)

You can choose between: Boots of Speed and Healt potions or u take Ruby Crystal with potions.
you can do it like u want but i prefer the ruby crystal :)

Later on buy Haunting guise for some early Magic Pen and Hp Maybe it helps u

First Item shall be Zhonyas if u play against AD, otherwhise u can build Rabadons and Magic Pen Boots against Ap Enemies

( I jumped many things cause u can build it after first items like u want like Deathfire Grasp or Maybe Rylais Crystal Scepter)

You Shall pick her when ur Team consists of HIGH CC and Enemies with Not dat much CC because they can easyli Interrupt ur ult and A team consisting of CC is nice for u to channel your ult And do nice plays

Alistar is high preffered just like Leona, Thresh Gnar etc

Easy Matchup against Orianna because u can poke her always and In lvl 3 u can do a little combo consisting of q+e+w for some dmg and do this again

More harder is Yasuo because he can poke you too with some early high dmg so Care

Zed is Hard too Just like Yasuo he can poke u hard

Ahri is A thing between because if u are good and ahri too its hard. Maybe u just need to master her a bit so u can improve your skill in outplaying enemies!
