Introduction

In order to carry effectively against a good team, you'll need survivability. Good teams will target you in teamfights and do everything to bring you down. That's why my above item build consists of 2 defensive items. Still i can carry effectively with my 3 offensive core items and my abilities.
Welcome!

My name is Klarry300 and i've been playing LoL since the start of 2011. I first came across Kog'Maw when we needed a ranged carry in our ranked team. I tried a lot of them, and i thought some were better than others. But my favourite became
Kog'Maw. After trying various builds i discovered a way of building him that i really liked and thought were the most efficient. After that, i always builded him the same way and now i wanted to share the way i build him with the community here. Hope you like it :)

Pros / Cons
Pros
![]() + Sick carry with massive damage, huge range, AoE slow and health-percent per hit, can tear the other team apart in seconds. + Both physical and magical damage makes you harder to counter than most carrys, though we focus on magical damage with this build (I'll explain why later). + Almost unmatched late-game carry potential, if left to farm in lane, Kog'Maw usually trashes the other team later on. With around 2 Attacks per second and 10% health bonus damage per hit you are a force to be reckoned with. + Long range bush-checker and finisher with ![]() |

Cons
![]() - SO squishy! If only focused on offensive attributes, you die very easily. This is Kog'Maws biggest flaw, as you are a carry and should stay alive and crash the party for the other team. Counter with some defensive items and runes, i'll explain later. - No natural escape-ability, relies on ![]() ![]() - 2 abilities are skill-shots that take time to master, but are relatively easy to use. |
Explanation
So my masteries consist mostly of the offense tree, and a bit in the defensive tree. Basically i try to maximize my damage, and go for both Armor Pen and Magic Pen, aswell as attack speed. Since Kog both does magic and physical damage with his autoattacks, he benefits from them both, but mainly we will do magic damage with this build. Remember, this isn't a AP Kog build, it's an On-Hit Effect/Attack Speed/AP hybrid build, and we need AS.
I put 9 points in defensive masteries because of his squishy early game, i need extra hp, armor and MR. As a carry i need to stay alive and still deal damage, it's really important.

Runes
**NOTE** IF YOU HAVE HYBRID RUNES THEY ARE A VERY GOOD CHOICE, IF YOU DON'T HAVE THOSE ROLL WITH THESE INSTEAD:
Greater Mark of Magic Penetration: The choice of this runes is easily undestandable, as you deal mainly magical damage you want to compensate for your otherwise low magic penetration.
SPACEGreater Seal of Attack Speed: In order to counter your relatively low AS early on and since later you will need AS to increase your damage output you could take these. They give more AS than the glyph ones too. It is very viable to switch these for
Greater Seal of Armor if you experience having trouble with physical damage.
SPACEGreater Glyph of Magic Resist: Mainly i take a lot of magic damage as a ranged carry, and these glyphs helps me a lot. You could swap these for AS or mana-reg, but i really recommend these.
SPACEGreater Quintessence of Magic Penetration: For the same reason as the marks, this boosts your damage and your damage is the most important as a carry. Simply put. But if you are willing to swap damage for survivability, go for
Greater Quintessence of Health as they help your squishy early game.

Ability Sequence Order
The sequence is pretty obvious. Take
Void Ooze at level one to easier escape/get first blood, it covers almost the whole bush if placed right. I then take
Bio-Arcane Barrage to harrass and deal damage with, and i complete my set with
Caustic Spittle right after. Then i max my W first in order to get as long range and much %health as possible. They will hate you for constantly poking them with this. I then max my Q cause it's AS and debuff + damage is well needed. If you feel like you want more short-range burst and AS, spec this one first.
Obviously, grab
Living Artillery at 6, 11 and 16.



Obviously, grab


Okay so now we've come to the items section, and here i'll explain my choices of items and why i choose them.

The next item you get is Malady. You probably have achieved a kill or two, or farmed well with your bot babysitter so you can get this. Early on Kog'Maws attack speed is quite low, even though he got a buff from his Q. In order to deal more damage with ![]() |

Around this time in the game, everyone buys their pair of boots. This includes you. The best choice for Kog'Maw as a carry in my opinion is Ol' Mercurys. These helps you against magic damage, which almost every champion got a bit of, and also it gives Tenacity to avoid CC. Kog'Maw is very vurnable to CC, you can't carry if your stunned, blinded, feared or debuffed by slows like ![]() ![]() ![]() |
CORE:



Ok so this is the core of the build, and how your build should look almost every game. These on-hit effect items are what makes you so deadly, and pretty hard to counter. All items give attack speed, which benefits


BOOTS:



Your choice of boots should differ depending on what you face and how well your game is going. Mainly you should grab Mercury's against a balanced team with CC's and such. However, sometimes you might face teams that don't have any magic damage or CC. Then i recommend you choosing depending on what you need. If your enemies are stacking MR, Sorcerer's would do better, and Berserker's Greaves AS isn't very needed since we get so much from other items.
DEFENSIVE ITEMS:




With all you offensive items you need to survive in order to deal damage, obviously. That's why i usually get 2 defensive items after my core, since i already have so much damage i don't need anymore. I almost ALWAYS get


Ok, so the reason i build like this is to deal as much damage as possible and still stay alive as i explained earlier. So let's calculate around how much damage we will deal;
Total DPS with 2 attacks per second = 720 - 780 damage
Analysis: ZOMG! Around 740 damage per second!? That's enough to devastate a team during a teamfight. Great so then we have full carry capability! And we probably got red-buff, magic pen and skills so our DPS is even higher! 740 damage just from auto-attacks!
But what about your defenses? Ok, let's say Lee Sin has an AD of 250 +. You have an armor of 170 with this build(!) and you remove 50% of his damage. Without your
Guardian Angel you would only remove about 30% maybe. Also you remove about 40 - 45% magic damage! Plus that you have an extra 700hp from
Frozen Mallet.
Conclusion: With this build you have a very high DPS and still are very durable. In other words, a great asset for your team. This is the main reason why i build like this, and i've tried to balance it as good as possible. Also keep in mind that you got a
Frozen Mallet and will slow your opponents into living targets.

Sometimes there are times when you don't need any defensive items, because no one is targeting you in teamfights (idiotic team). Well, then feel free to grab a ![]() ![]() Grab this one if: No one is targeting you or you are facing ![]() Grab this instead of: ![]() |
![]() |

If you notice yourself only taking magical damage, grab this item. It's passive is just awesome, it breaks casters combos and let's you get away with that little health from ![]() Grab this one if: Your only taking/facing magical damage Grab this instead of: ![]() |

Sometimes you only face physical damage instead. In order to prevent that ![]() Grab this one if: Your only taking/facing physical damage Grab this instead of: ![]() |

As you might have noticed, most of your damage comes from magical sources and if the enemy is stacking LOTS of heavy MR in order to counter you, and by that i mean a few hundred. Then this item is great to grab, it boosts your abilities Q and E by about 50 dmg and penetrates 40% of their magic resist. Grab this one if: Your enemies are stacking MR Grab this instead of: ![]() |
General
As a carry, your goal is to deal as much damage as possible. To achieve this there are some various things you need to know. Below i will list some skill-usage to use in lane:
+
I usually harrass with my W because of it's range. With this you can stay behind minions and launch auto-attacks on melee's who try to keep up with your farm. When you hit 6, your ultimate is of great value in terms of harrassment. Just don't spam it to much, and wait for the mana-increasing debuff to go off before you launch it again.
+
This combo is great if you are in medium-range so you can use your Q and unload a few auto-attacks with your W.
+
+
+
+ Finish with
This is your nuke combination, slow with Void Ooze, debuff with Spittle and unload auto-attacks with the extra speed from Surge. Great to do from a bush, this is also your ganking combo. Remember that Surge increases your AP but also reveals that you will attack.
Your role in teamfights are very important. You are the carry. Here's a list of what you should do:
Harrass

Finisher

Teamfights
Your role in teamfights are very important. You are the carry. Here's a list of what you should do:
- Deal as much damage as possible. Switch target fast if your target either is dead or is getting chased by someone else on your team. Don't run after a flashing enemy in the start of a teamfight, switch target instead and let your assassin handle it.
SPACE - Kill tanks when they expose themselves. This might sound odd, but a tanks job is to grab your attention and by doing so he runs in first and puts himself in bad positions. With your high %health on-hit effects you'll rip him to little pieces while sitting back in safety.
SPACE - Prefer melees over ranged. You can easier kill them without getting killed yourself.
SPACE - Wait for your tank to initiate. Don't EVER start a fight by running and hitting their tank or carry. Your role is to wait for him to start the fight, then start activating your abilities and bring the heat from afar.

The optimal lane for most ranged carry's is bot + support. Let your AP carry handle mid, because if you go bot + support you will get much more farm and will be able to deal damage fast.
Laning partners

This fabulous support champion is a perfect match for you. His stuns and heals are just amazing. His ultimate also boosts your AD and AP now. Not many champs can stand the harassment of stun +



Another great support champ, the queen of babysitting. She boosts your AD and got loads of CC to help you. Also her ultimate and Q blows them away, great when facing melee's since you are so long range.

Yes, a tank. Even though she might not have any heal, her CC and passive remains awesome. She's proably gonna give you a lot more kills than supports, but you will probably have a harder time farming without the heals and shields.

So in this section i thought i would post some scores, here's one i got today 29/7, non-ranked but the score was good so i'd post it anyway. Their Leona was so bad, look at her items!

I will upload more soon, and you are free to send me pictures if you want to.
I will also add videos
I will also add videos
I couldn't make this guide without help from other people. Big thanks to:
- All my friends and teammates in my ranked team WMO. Wouldn't write this guide if we never had started playing LoL together :)
SPACE - JhoiJhoi for her amazing guide on how to make guides. It helped me very much on how to create and edit guides, and i've used parts of her layout and build ideas. Here's a link to her guide: Guide on how to make Guides.
SPACE - Other guides that have inspired me, personally i love these two great guides: Spin to Crit by Palthios & Ferrovial's Teemo Guide

Thanks for reading!

So now you have come to the final chapter, and i hoped you enjoyed reading my guide and that you will try out the build and evaluate what i have wrote, so you can have a better experience when playing Kog'Maw!
I did this build and guide for fun, and by the fact that i feel i wanted to share how i play Kog and by that i really think building him this way is very efficient. Hopefully you can leave a comment on what you think should be improved and what is good. I realise i might get downvotes from people who have other opinions on how to play him, but this is only an optional way of playing him and it is how i do it.
