[9.8] Kog Maw guide by misterfirstblood

By misterfirstblood
Hello guys, I'm MisterFirstBlood from EUW and today I'm gonna show you how to play Kog maw in Season 9.

Kog Maw has such an extremely high skillcap. Thats why scripters and high elo smurfs always abuse him.

If you really think you're a mechanically good player Kog maw is definitely the right champ for you.
Pro's and con's Back to Top
+ Insane Lategame performance.
+ Able to melt Tanks insanely fast.
+ Very high attack and spell range in lategame.
+ Tons of mixed Damage.

- No Mobility makes him easy to gank.
- You need either shields or CC from your Team to deal the damage.
- Weak early Game.
- Hard to play/master.
Spells Back to Top
Passive: Icathian Surprise

Innate: Upon taking fatal damage, Kog'Maw remains active for 4 seconds, becoming disarmed, invulnerable, untargetable and gaining up to 40% bonus movement speed over the duration. He then explodes, dealing 125 - 550 (based on level) true damage to all nearby enemies.

Q: Caustic Spittle

Passive: Kog'Maw gains bonus attack speed.
Bonus Attack Speed:
15 / 20 / 25 / 30 / 35%
Active: Kog'Maw launches a corrosive projectile in a target direction, dealing magic damage to the first enemy it hits and reducing their armor and magic resistance for 4 seconds.
Magic Damage:
80 / 130 / 180 / 230 / 280 (+ 50% AP)
Resistances Reduction:
20 / 22 / 24 / 26 / 28%

W:Bio-Arcane Barrage
COST: 40 Mana COOLDOWN: 17

Active: For the next 8 seconds, Kog'Maw's basic attacks gain bonus range and deals bonus magic damage on-hit, capped at 100 against minions and monsters.

Enhanced Range:
630 / 650 / 670 / 690 / 710

Bonus Magic Damage:
3 / 4 / 5 / 6 / 7% (+ 1% per 100 AP) of target's maximum health

E: Void Ooze
TARGET RANGE: 1280 SPEED: 1350 COST: 80 / 90 / 100 / 110 / 120 Mana COOLDOWN: 12

Active: Kog'Maw spews a ball of ooze in the target direction, dealing magic damage and slowing enemies for 1 second.

Magic Damage:
60 / 105 / 150 / 195 / 240 (+ 50% AP)

20 / 28 / 36 / 44 / 52%
The ooze lingers for 4 seconds, slowing all enemies within the area for an additional 0.25 seconds.

R: Living Artillery
TARGET RANGE: 1200 / 1500 / 1800 EFFECT RADIUS: 100 COST: 40 - 400 (based on casts) Mana COOLDOWN: 2 / 1.5 / 1

Active: Kog'Maw launches a ball of acid into the air that drops after 0.6 seconds at the target location, dealing magic damage, increased by 0% - 50% (based on target's missing health), and revealing enemies hit for 2 seconds.
Magic Damage:
100 / 140 / 180 (+ 65% bonus AD) (+ 25% AP)
Living Artillery's damage is doubled against enemies below 40% maximum health. Each subsequent Living Artillery within the next 8 seconds costs an additional 40 mana, capping at 400 per cast.
Items Back to Top
Kog Maw needs on-hit damage items.
Since rageblade scales with ad and ap it's better to buy blade of the ruined king before rageblade but these 2 items + berserkers are your ultimately core build.

At this point your damage is that high that you can out trade and melt everybody.
However if you need more damage go for wits end, if you need cc removal get a scimitar, if an ad assassin is shutting you down go for guardian angel and otherwise get runaans.

The new Wit's End is also a pretty strong choice, but i only recommend it when you are against lots of AP.
Runes Back to Top
Since Fleet Footwork kinda disappeared from the current meta Lethal Tempo fits best on Kogmaw. Overheal synergies well with your blade and dorans and alacrity and Coupe will boost your damage up by a lot.

To reach your powerspikes very early i also recommend you to go in inspiration second to benefit from free boots and Cookies.
Tips Back to Top
- Set Key Bindings for moving and attack moving om your keyboard and learn how to handle it. With an attack speed of 3-4 you will not be able to kite fluently by only using the mouse.
Use Practise tool to learn it. Seriously.
- When chasing an enemy make sure to hit E first to slow him, hit Q after because it's a skillshot and easier to land when your enemy is already slowed and then activate Blade of the ruined king + W and kite towards him and go for the kill.
- Dont use R too often in a row. You will run out of mana very fast.
- Red buff is one of the best things u can get with kogmaw. With an attack speed of 3 or higher and your E People wont be able to escape anymore.
- Your ult range at level 16 is ridiculous. Go to base and grab your farsight trinket and try to snipe your enemies.
- You don't always have to kill the carries of your enemies team. Tanks will not survive for a long time neither if you attack them constantly.
- Use your range to shoot over walls like the dragon or baron pit and attack enemies from a safe distance.
Summary Back to Top
At least kog maw is a good practice to handle high attack speed, orb walk and kite fluently.
But you will need good reactions and a lot of games to get better in these things. Also games can be very frustrating if your team is feeding and you get dived early.
His impact in early is very small but if you reach late it's one of the best champs.
