Kog'Maw was released by Riot Games for their game League of Legends on V12.12 as a Marksman champion from The Void. Kog'Maw is a very good pick for rank due to its low ban rate and good win rate for Patch 12.14. This League of Legends champion is a beast in late game, especially with the right build and item path. He's still a pain to deal with even when he dies due to his passive, Icathian Surprise.  

Best Kog’Maw Build

In this article, we share our Kog'Maw Build guides to help you get an awesome win streak in your League of Legends games.


Best Kog’Maw Runes

We recommend getting "Precision" runes and "Resolve" for this champion if you're going bot lane.

Best Rune Path Precision
Best Keystone Lethal Temp
Best Slot 1 (Rune) Triumph
Best Slot 2 (Rune) Legend: BloodlineLegend: Alacrity Conditioning
Best Slot 3 (Rune) Last Stand
Coup de Grace

Lethal Tempo maximizes Kog'Maw's damage output. The extra attack range Lethal Tempo gives is also helpful with chasing down low HP enemies that are dashing away. Triumph gives extra healing and extra gold which will be helpful for you to get full damage items early. Legend: Bloodline is a good rune to help you sustain longer while laning. As for your fourth rune, Last Stand is a better option in this rune set than Coup de Grace for Kog'Maw's playstyle.

Under “Resolve”, we have “Conditioning” which gives armor and magic resist, and “Overgrowth” which maximizes your health when you farm. This will make Kog'Maw last longer in team fights.

Best Kog’Maw Rune Shards

In the bot lane, it's best that you get “Attack speed”, “Adaptive force”, and “Armor” for your rune shards to amplify his damage output further and take less damage.

Best Rune Shards Effect
+10% Attack Speed
+9 Adaptive Force
+6 Armor

Since these rune shards grant you a bit of everything, all you have to do is play safely until you get your first item.

Best Kog’Maw Spells

Since Kog'Maw has very low movement speed, it's best that you have “Flash” to avoid ganks and “Exhaust” as secondary Summoner Spells for chasing down low-health enemies.

Although it’s super fun to use “Exhaust” to chase enemies, it can also be your means to escape if you don’t have “Flash” available.


Best Kog’Maw Abilities Order

For this ADC build, prioritize maxing out “Bio Arcane Barrage” first. After that, put your points into “Caustic Spittle”. This corrodes an enemy's armor and magic resist for a short while, making your auto attacks more fatal.


Put points into “Living Artillery” as soon as you can so you can, since "Living Artillery" lets you attack from distance. This will be pretty good to combo with “Caustic Spittle" along with "Bio Arcane Barrage". You'll want to max out “Void Ooze” last since your runes and damage items aren't reliant on your magic damage.

Best Kog’Maw Items

Here's the following item path for each stage within the game.

Best Starter Kog'Maw Items

For this Kog'Maw ADC build, you're going to use as early game items the "Doran's Blade", a "Health Potion", and a "Stealth Ward".

First Item Second Item Third Item
Doran’s Blande
Health Potion
Stealth Ward

Best Mid Game Kog'Maw Items

Once you've reached the mid game with Kog'Maw ADC, you should have these items bought and equipped: "Guinsoo's Rageblade", "Berserker's Greaves", and "Runaan's Hurricane".

First Item Second Item Third Item
Guinsoo’s Rageblade
“Berserker Greaves”
Runaan’s Hurricane

The first one grants you a nice Attack Rate and Crit. Rate that Kog'Maw needs, "Berserker's Greaves" offers some nice Armor to resist damage, and lastly the third item allows you to attack multiple enemies at the same time.


Best Late Game Kog'Maw Items

"Titanic Hydra" suits this Kog'Maw build very well thanks to the extra Damage and HP. Meanwhile "Wit's End" further increases his Attack Rate and Magic Resistance, as well as offering him even more damage in League of Legends.

First Item Second Item Third Item Fourth Item Fifth Item Sixth Item
Guinsoo’s Rageblade
“Berserker Greaves”
Runaan’s Hurricane
Titanic Hydra
Wit’s End
Blade of The Ruined King

Finally "Blade of The Ruined King" will give you some Life Steal to survive during team fights in League of Legends so your passive ability is as delayed as possible. On some occasions “Phantom Dancer” can be a good replacement for “Wit’s End” in this Kog’Maw build.

Best Champions to pair Kog'Maw with

Currently, Zilean, Renata, and Senna are excellent pairs for Kog’Maw since they all give them the buffs, heals, or protections he needs throught the game.

Champion Win Rate % Icon
Ziliean 58.6% Zilean
Renata 53.9% Renata Glasc
Senna 53.6% Senna

Renata is a great option because she can use her ultimate in the best moment to create the perfect opportunity to delete the enemy team.

Strongest Champions against Kog'Maw

Champions who can poke Kog’Maw from really far distances are his doom, which can lead him to lose CS and eventually fall behind if he doesn’t play his cards right.

Champion Win Rate % Icon
Miss Fortune 46.4% Miss Fortune
Caitlyn 47.3% Caitlyn
Kai’Sa 47.3% Kai'Sa

Some of these champions with a high chance to win are Miss Fortune, with her “Bullet Rain”, or Caitlyn with her “Piltover Peacemaker”.

Weakest Champions against Kog'Maw

Ezreal, Nilah, and Kalista are easy matchups for Kog’Maw, since you have an advantage in the way their kit of abilities work.

Champion Win Rate % Icon
Ezreal 61.7% Ezreal
Nilah 60.0% Nilah
Kalista 59.0% Kalista

Nilah and Kalista have a tough match since their ranges aren’t that wide, but poor Ezreal is the one with worse luck against our friend from the void.

With this in mind, we hope that you now are well aware on how to build Kog’Maw and stomp on every lane during your games, good luck, Summoners!
