Hello guys today we will be having a conversation: a very HUNGRY conversation with my favourite ranged AD carry
Of course I am talking about Kog'Maw

Ah Kog'Maw...What's so marvelous about Kog'Maw?
Whell if you really want to find out keep reading this guide

A video of Candy Panda. skip to 30 seconds.


First of all this is an AD build of kog'maw. Just because you think our hungry friend should be AP, don't downvote. Kog can be played the 2 ways, but i prefer AD.
Never rate a guide without comment and trying the build first.

Credits to jhoijhoi for the template, which you can find here.

Pros / Cons


+ Does insane HYBRID damage
+ Can outrage a Caitlyn
(after w hits max level)
+ Awesome /joke
+ Can destroy tank and squishie alike
(remember to kill the squishies first)


- VERY weak till about lvl 4
- will get targetted a lot
- is quite hard to play and master
- no true escape mechanism
- you kill people with vomit
- always hungry

Ok so why these masteries?
we go offense to increase our total damage output, which makes us an even greater pain in the *** when we hit people.
For utility I go there for Swiftness because kog maw is REALLY slow and for buff duration (red buff on kog is scary).

Greater Mark of Lethality

Greater Seal of Mana Regeneration

Greater Glyph of Scaling Magic Resist

Greater Quintessence of Lethality

  • greater quintessence of Desolation: I choose this quints because they help you all game long. you're damage will be hybrid, but it will mainly come from physical sources.
  • greater mark of Desolation: Same as quintessences
  • Greater Glyph of Scaling Magic Resist: Magic Resistance per level. at lvl 9 you get the bonus from flat ones so I think this ones are tons better. This will avoid you getting 1 shotted by mages
  • greater seal of Replenishment: Sometimes you overreact in your skill usage, expecially with Kog'Maw this will help you recover without having to go base. if you play carefully you can stay in lane till lvl 5-6 without a single base. usually I get berserkers and almost full wringle's in a first b thanks to this runes.

Summoner Spells

Good summoner spells

Exhaustis a very awesome spell

you can use it for offense AND for defense since it completely slows and reduces damage other champions inflict. this can get you some pretty nice kills due to peopel thinking they can kill you before you do.

your friendly neighbour Ghost since the flash nerf, my new mobility spell. the only problem with this is that if you get stunned or immobilized, this won't save you as Flash, but I consder ghost to have a better offense/defense balance that flash.

since the flash nerf, I consider that it has lost most of its value, but people still like it. if you take it remember to take the point out of Improved Recall to upgrade Flash.

nice summoner spells

When you begin your experience as kog maw, this might be usefull.

for those wtf boom moments when you want to kill everything you see.

if you are midding, you might wanna take this.

bad summoner spells

Never liked this, will never like it.

You are not a jungler

Icathian Surprise
When you die you start a chein reaction that allows you to move faster and makes you explode for true damage after a few seconds.
When you die, run at people. The damage cannot be mitigated and increases with your level.


BY ALL MEANS DON'T DIE ON PURPOSE! you give gold to the other team and you will be hated by that, play safe and try not to die. not using this passive is better than using it but if you get nuked on a teamfight and die just trow yourself at the squishies and blow them up.

Caustic Spittle
Passive: more atack speed Active: deals magic damage and reduces target's armor and magic resist
using the active does not break the passive, so if you get range for it use it. just don't stop your super ranged auto-atacks thanks to your w to use this because you will lose damage. if you get range, use if not just keep auto atacking

Bio-Arcane Barrage
your auto attacks gain extra range and you deal extra magic damage to your opponents based on they're maximum health
The bread and butter, and my favourite skill on Kog'Maw. with this skill at max lvl, you outrange a Caitlyn, and you deal nice damage. this ability scales with AP but you need 100 AP to gain 1 extra percent damage. not worth it.

Void Ooze
Trow a pool of vomit in the ground that deals a litle damage and slows your opponents
A skillshot that slows people and helps you catch them so you can continually rape them with your w auto-atacks. neat. learn how to place this and you will be a great asset to your team.

Living Artillery
sends a missile into the air that after a short delay hits the place where you trew it, dealing magic damage and revealing hit units for 4 seconds
DON'T SPAM THIS. each time you use it in sucession, it drains more mana. trow one, wait 6 seconds and trow another. unless youa re really going for the kill and you need jsut that extra last missile don't use it in sucession.

How to use your ultimate

So I decided to make this session due to seeing a kog'maw completely failing at ult positioning.

Uploaded with

in this screen I am trying to hit morgana with a ultimate, as I know she will retreat when she hears the rocket, I point it slightly backwards

Uploaded with

As I know morgana is going to try to go trough middle I point my rocket in that direction. You have to see the speed of your oponents when they are running away from you.

Uploaded with

Here I do one of my favourite tecnincs. dragon scouting. As the dragon goes to try to hit you he gets out of his zone and shows the enemies that are there. You can try to steal dragon this way =)

Credits to Icefaith for helping me with these screenshots (even though she killed me twice =P)

A major point of this guide. your item build.
In here i will explain the item set I buy in every game and the reason why.
In every game, no matter what the team I do these items

Berserker's Greaves/ Wriggle's Lantern/ Zeal

I buy berserker's for mobility and some extra atack speed
I buy Wringgle's for extra damage, lifesteal and resistance and the nice proc for dragon kills and/or minion farming
I buy zeal for extra mobility, crits and atack speed
Remeber that even with lvl 2 boots, kog is a bit slow compared to other champions. most champions can outrun you if you don't slow them with Void Ooze or red buff.

game start

Before I continue talking about items, just a little something about laning.
Kog'Maw in my opinion only has 2 possible lanes nowadays: mid, or duo bot with supporter.
this is because at low lvl's it is hard to farm creeps with kog maw. your auto attack range is ridiculous, your hit 52 (runed) on minions at lvl 1 and you are VERY squishie.

When you start the game, you have 2 main ways you can start:

+ 3
For me speed equals survival. expecially when you receive massive damage with a champion like kog'maw. plus the potions will help you stay in lane longer.


I only take this if I am with a supporter at bot lane, to help me with last hits, and give me some extra health.
mid game
By now you should be starting to be a great threat to your enemy team, your w is almost/maxed, by here you should have finished the core build.

Berserker's Greaves/ Wriggle's Lantern/ Zeal

People should be afraid of you now. you have a minimum damage output and a decent atack speed.
try getting some kills about now, and don't forget to get dragon with the help of your team.

Again I have 2 ways from here.
If I am doing well and I know I can hang on a bit and farm some gold I get a B. F. Sword
If you are having dificulty killing enemy champs get a Pickaxe.

Either way you are farmimg to get one thing: Infinity Edge. After infinity edge your damage output will be insane.

still in the mid game, you evolve your zeal into a Phantom Dancer.
late game

At this point if you are fed you should be 2 shotting mages that have no armor and doing the same to most ranged AD carry.

If you are not fed... well i sugest killing creeps in the jungle and only apearing for teamfights, and try not to die.

after a Phantom Dancer again I have 2 choices

Madred's Bloodrazor


The Bloodthirster

I choose them on the basis of: I need more atack damage and more survivability based on lifesteal, or should i up my magic damage and get a litle armor and atack speed.
Usuallly I go for the bloodrazors.

Normally the final item on the build is either the remaining from the other choice or something defensive.

If the game still lasts I will replace Wringgle's Lantern with a The Bloodthirster With your massive damage, having 2 bloodthirsters makes you almost unkillable, plus you get some nice AD boost.

Situational items

If you do these items, they will relace your late game items. Do them fast, like if the other team has a fed mage, do banshee's veil as fast as you can, but remember that it is replacing one of your late game items (bloodthirster or bloodrazors)

If other team is CC heavy sell your berserker's and grab this.

In my opinion one of the best items in the game. ultra cheap, gives you 50 magic resist and has a 1 minute cooldown efect that acts like a Cleanse. Bye Bye ignites, stuns and all others =)

Nice health boost, mana boost and magic resistance. Plus that shield will help you get trough most nukes.

Super fed AD carry almost one shotting you?, grab this and make him feel the pain!

health, armor and people get slowed when they auto-atack you
Not bad.

show that nasty Karthus who's boss with this

nice health, and a slow with your auto attacks. Make them suffer.

resists and a rezz. unfortunately you don't activate your passive and then rezz =(

If you see that you have no chancce of survival even if you run away, try nuking the squishier target chasing you. if you get them low enough you might get a kill with Icathian Surprise

If you get Exhausted trow all of your spells (void ooze, caustic spittle, living artilerry 2x) and the activate your w and auto atack them to death (also works with Teemo's blind.)

Don't do the last thing I said if you think you can still escape (remember to ignore this one on Teemos's blind.)

Remember to keep an eye on the time remaining on Bio-Arcane Barrage after it ends you may have to wait for the cooldown to keep nuking people.

Kog'Maw is so powerfull that he makes Shen fail.
