my name is Corebreaker. I am playing on the EUW server and I recently found some old screens, which inspired me to write this guide.

This is my first guide on MOBAFire and my native language is not english, so pls be patient and comment if you find something that needs to be fixed. :)

This is a hybrid on hit guide on Kog'Maw for duo bot. I had preety good games following this concept / guide andi hope that you guys can have some too. This means that you wont be a real ad carry, so your damage vs towers might not be that high, but your mix of physical and magic damage with all that %-based damage will wreck even the hardest tanks in no time. :)

If you dont agree on something written in this guide, feel free to change things for you, since this is just my personal preference. If someone has CONSTRUCTIVE (!!!) criticism, I would appretiate to see it in the comments.

So have fun reading my guide :)

6/6/2012 - Changed my mind about the Amorpen Red's. Changed it for Flat AD.

Guide Top


Icathian Surprise - Upon dying, Kog'Maw starts a chain reaction in his body which causes him to detonate after 4 seconds (he can move in this time), dealing 100 + (25 x level) true damage to surrounding enemies. Kog'Maw will gain additional movement speed upon entering this state

Run at people when you die, you blow up and deal true damage (cannot be mitigated). I would like to point out to keep this in mind if you think you will probably die from a gank. You can turn around and get one of your gankers low enough to kill them with your passive. By no means TRY to die, but keep it it mind.Got me even double kills out of a gank. People, especially in lower ELO levels tend to forget about this passive.

Caustic Spittle - (Passive) Increases attack speed (Active) Kog'Maw launches a corrosive projectile which deals magic damage and reduces the target's armor and magic resistance

When you use the active the passive does not go away, so there is no reason not to use it when you start DPS'ing someone.

Bio-Arcane Barrage - (Active): For 6 seconds, Kog'Maw's attacks gain additional range and deal a percentage of the target's maximum health as magic damage (max 100 damage to monsters).

The wording here confused me when I first started playing Kog. From the wording it sounds like this effects his skills (caustic spittle, void ooze, living artillery) but in reality it only increases the range of his auto attacks. So do not use it to try to finish off people with your ult! :) This is the bread and butter of attackspeed Kog and in my oppinion by far the best skill of Kog's kit. This is what you should use every time you start dpsing in a fight, and to harass in lane.[/url]

Void Ooze - (Active): Kog'Maw launches a peculiar ooze which deals magic damage to all enemies it passes through and leaves a trail for 4 seconds which slows enemies who stand on it.

Nothing much to explain here. Straight line aoe slow.[/url]

Living Artillery - Kog'Maw fires a living artillery shell at a great distance dealing damage and revealing targets for 4 seconds. (150% bonus damage to champions).

* Cost: 40 Mana (each subsequent Living Artillery in the next 6 seconds costs 40 additional mana, capping at 200 per cast)

* Area of Effect

I just wanted to note the extra mana cost for Living Artillery's used in quick succession, and that it has a small area of effect (aoe). This scales with BOTH ap and ad, which with this build makes it great. We don't rely on this for the majority of our damage, but with this build it can do significant damage to fleeing enemies.[/url]

I like the setup i suggest at the top, since it gives you more mana regen, but you can easily switch the utillity points into defense :)

RED - Flat AD / Mpen what you prefer more, although i find the Flat AD runes slightly more usefull

YELLOW - Flat Armor nothing too discuss here, since you will most likley face an ad carry

BLUE - 1 Falt AD rune, since this gives you 1 extra AD, although it just displays 0,28. This will give you a slight edge in AD over your opponnent. Rest MR per level.

QUINTS - I like the Flat AD runes since you have already a pretty tough early game. And MPEN is just not worth the price and place on Quints. Also Runes start to fall off as longer the game goes on, since you get more stats. Thats why i suggest Flat AD Quints to boost you early game a bit further.

Summoner Spells

Flash + Heal/ Ghost/ Exhaust

Heal - It just gives you so much more lane dominance, thats why i suggest it.
Ghost - Flash + ghost? damn safe ;)
Exhaust - I would say is the worst choice of the 3 , but it all comes down to your playstyle ;)

Dont forget to change your masteries according to which summoners you are using.

Boots of Speed Health Potion Health Potion Health Potion - These will give you some moventspeed, which Kog does deffinitly lack and some nice sustain through the 3 hp potions.

Vampiric Scepter - this is what i recommend since it gives you sustain, through lifesteal, and in my oppinion you wont need the boots that hard at the start since you gonna have a support. In case you didnt already know, Nunu is by far the best support for Kog'maw.

1st Trip back
This depends on how your lane is going.

Madred's Razors - If you are doing the harras
Berserker's Greaves - If you are getting harrased

Core build

Now get either Madred's Razors or Berserker's Greaves, depending on which you got first. Now start building your Madred's Razors into Madred's Bloodrazor by buying Recurve Bow. When you finished your Madred's Bloodrazor go on by purchasing Zeal.

Side note: if u started Boots of Speed, get your Vampiric Scepter before Zeal!!!

After Zeal I personally like to go for Guinsoo's Rageblade because Kog just benefits from all the stats it gives so much, but if you dont like this item, i would switch it for a Frozen Mallet (I dont like going the mallet way, because you give up so much damage, but the health and slow are also fine).

Now finish your Phantom Dancer.

Now the Physical Damage will get a nice boost, because it's time for our The Bloodthirster.
This is by far the item that gives us the most AD.

Rest is pretty much up to the enemy team.
They stack MR ( at least 3 of them) - Void Staff
They dont - The Bloodthirster Nr. 2

Now, if you got that far, you can either switch your Berserker's Greaves for another Phantom Dancer, this would mean that you give up a bit of moventspeed for a giant amount of AS and Crit (Just sell your Berserker's Greaves if you can afford the full Phantom Dancer!!!!!

Or just buy all the ellixiers from now on. Prioritizing Green, then Red, then Blue. Oracles is not helping your combat efficincy, but if they got stealth champs or no one on your team has one, fell free to buy one. :)

Quiet a short Guide, i think.

Hope you enjoyed it :)

Still testing:
Switching Guinsoo's Rageblade for Infinity Edge / Wit's End
