~I~ Why starting boots?

I know! Alot of peoples have sent me PM's/comments abut why to start boots!

This is the reason I use it:
Believe it or not, Kog'Maw have a very bad escape! So, you basicly need the boots early to be able to juke/flee better, that's the best way of starting even if pretyt much everyone recommend (nowdays) crystaline flask, that's the reason hope you'll respect that part of the build and thanks for reading my build :)

~II~ Pros & Cons

+Strong poke!
+Best ADC late!
+Fun to play!
+Awesome passive!
+Better than ever at S3!

-Bad fleeing!
-Weak early-game!
-Need "special" support!
-Blow himself upp >:C
-Cute so i die o__ O


You may also ask yourself: Why start with boots? Even though Flask start is good i recommend this hardly beacuse kog'maw need to flee more than he need the substain (may sound weird but it's true!!!)

~III~ -Lore-

NINJAH-II- When the prophet Malzahar was reborn in Icathia, he was led there by an ominous voice which thereafter anchored itself to his psyche. From within, this voice bestowed upon him terrible purpose, and though Malzahar was no longer tormented by its call, the voice did not cease its unrelenting summons. This baleful beacon's gentle flicker - now fastened to Runeterra - drew forth a putrid beast that ambled across a threshold it did not understand, widening a fissure between spaces which were never meant to meet. There amongst the haunting ruins of Icathia, Kog'Maw manifested in Valoran with unsettling curiosity. The spark which led him to Runeterra teased him still, urging him gently towards Malzahar. It also encouraged him to familiarize himself with his new environment, to the stark horror of everything he encountered on his journey.

The enchanting colors and aromas of Runeterra intoxicated Kog'Maw, and he explored the fruits of the strange world the only way he knew how: by devouring them. At first he sampled only the wild flora and fauna he happened across. As he traversed the parched Tempest Flats, however, he came upon a tribe of nomads. Seemingly unhampered by conventional rules of physics, Kog'Maw consumed every nomad and any obstacles they put in his way, amounting to many times his own mass and volume. The most composed of his victims may have had time to wonder if this was due to the caustic enzymes which stung the ground as they dripped from his gaping mouth, although such musings were abruptly concluded. When his wake of catastrophe reached the Institute of War, an enthusiastic Malzahar greeted him with an enticing prospect: taste the best Runeterra could offer…on the Fields of Justice.

"If that's just hungry, I don't want to see angry."
― Tryndamere, the Barbarian King

~IV~ Kog'Maw.... Why?

Have you asked yourself... why kogmaw? This is how i explain it for you :)


No but he's the cutest little monster in the universe and i Luv (<3) him! Also he's the best ADC in the game (late-game), better than Vayne and greaves actually! And there's no-one that can counter him bot if he haves a Mr.LovesDudesAndThinkGemsAreTrulyOutrageus bot! ( Taric)!

~V~ Masteries


Durability + Veteran's Scars
-Theese two uppgrades is why I actually uppgrades the deffensive mastery tree at all! It will give you more substain in the lane basicly! ---

Summoner's Resolve
- This will power your Heal or eventually your Barrier, these spells are really usefull for Kog'Maw, and this is a must-have for Kog'Maw! ---

- This little ammount of armor will help Kog'Maw against mostly the other adc, and sometimes if you have to tank the minions! The little ammount of armor can make a big difference! ---

- This mastery even though it's in the start of an mastery tree and it is not very high valued is actually very good for Kog'Maw! The reason why it's like that it's beacuse he's really just strong late-game! And this mastery will power him upp a litle bit early-game!---

Deadliness + Weapon Expertise
- This two abilities will basicly power up Kog'Maw early game! It's really good masteries and should be choosed if having either 21 or even 9 in offensive!---

- Isn't really much to say abut this than that it does alot of daage together with other % dmg increase on masteries! worth some points with other words!---

Lethality + Frenzy
- If i say it myself this is where the really good stuff begins! Lethality is just over-all OP when you compare the ammount of points to the effect! Frenzy is probably the best mastery in the game! After a crit (every atack with Kog'Maw) you will get AS! AWESOME! With other words!--- wiki

Brute Force + Sunder
- These two masteries is just very good/basic masteries with some strong early-game power! really good to spend some point on ^^---

- This ability is a really good mastery that will basicly give you more damage against targets with low health! This works as an (f-Corse) damage tool, as well as taking last-hits and just being pro beacuse you reached lv 21 ;)---

~VI~ Runes


Greater Seal of Armor

Greater Mark of Armor Penetration

Greater Glyph of Scaling Magic Resist

Greater Quintessence of Attack Damage


Greater Seal of Armor
For Seals i choose the early armor for Kog'Maw, this will offer you strong anti-adc and makes you more substainable against junglers!


Greater Mark of Armor Penetration
For Marks i choose the Armor Penentration for being able to kill that rammus! (we have all been there have we?) And picking those runes will make Kog'Maw able to don't level any armor penentration beacuse of his high magic damage!


Greater Glyph of Scaling Magic Resist
For glyphs i strongly recommend the runes above, it will give you substain agains the apc-assassins and will probably save you ALTO if you use these runnes!


Greater Quintessence of Attack Damage
For quintessances i really need some AD after the all deffensive runes and your armor penentration marks! So this isn't even i recommend, it's a "Must-Have" for Kog'Maw if you play him with the other runes!!!

~VII~ Summoner spells!


-- Flash:
This spell will be really usable on Kog'Maw! You can basicly use this mostly for fleeing/chasing but it's mostly good beacuse of the positioning an ADC should have! If you for example stand in a bush with your team! Then basicly the enemy team comes and you're very close to them! then you might have to Flash away and get a good positioning so you can deal damage to you'r foes!

-- Ghost:
This spell is actually pretty bad on Kog'Maw but if you're on a smurf acc and are not on lv 12 yet is probably the best option for Flash!

-- Ignite:
Ignite is the main spell for Kog'Maw if going anywere alse than bot adc! (maybe Mid i don't know), i don't recommend usig this on bottom beacuse why would you wanna suicide instead of being able to survive and pick the kill?

-- Heal is 1 of 3 of my main secondary spell for Kog'Maw! The Reason why i choose this is beacuse partly trolling tower tankers! But mainly it's to be durable on the lane and pick upp much farm as needed as well as deffend yourself in teamfights! --

-- Barrier is a new ability who actually works pretty well in any cir***stanes! It's like a scramble of Heal and Cleanse! I pick mostly Heal but agaist champions with grievius wound abilities ( Tristana), i pick Barrier beacuse it doesn't matter if you have that effect on you Barrier's shield will probably absord it! --

-- This summoner-spell is my recommended pick with Kog'Maw in almost any situation! Why i pick this spell is beacuse LiLStormcloak forced me to :( NO! But this is the summoner-spell that actually makes it able to flee with Kog'Maw! --

Champions spells, NOT! to pick:

Revive: Worthless and to long CD to use
Smite: We're no jungler are we?
Exhaust: Double of these isn't needed on a lane!
Clarity: Kog'Maw has no strong mana problems!

~IX~ Items!

Main Items And Explenation:

Runaan's Hurricane is a new season 3 item that's my item of choise in the opening! Before there was two choises to start with! The first option was to start AD with a B.F. Sword, that offered you really strong mid-game power but early game, you were like a blinded Master Yi with AD build... The other option was to start with a Zeal and that way get both early and late game damage with your Phantom Dancer.
Now to the classic ad-carry item! I can't actually not say an adc i wouldn't recommend that for! It will give you the really strong AD damage and will add an passive for your critical hits so they will deal 250% of your Ad insted of 200%! This one can be bought first if you really just focus on mid/early game and have maybe use early AD runes! This is a Must-Have for Kog'Maw and have always been!
This item is for the awesome attack speed an crit. chance! In the past season it could replace the shoes very-late game beacuse of the attack speed, I think it still can and actually that you should make it if you need to be an extreme carry! But if you need more movement speed for positioning and fleeing/chasing stay with the boots!!! This is either your first or third item in the order!
I think everyone know the effect (passive) of this item! Gives you a second life bro! This is really a good item for the standard ad-carry build! I just want to say noobs doesnt buy this for ad-carries! That's really ****py! Buy Guardian Angel when you have all the needed carry items ready!
This is a item that really gives you the last boost for Kog'Maw that will make him super-anti-tanky, buy this item, just buy it! Really gives you like 200hp every shot to your own life with the passive and life-steal! I think Kog'Maw is the only champion i also recommend it for! (carries), On your preferance, you can buy a The Bloodthirster insted of it!
OK! Now one guy really pisses me off when I say this item is in the build! Now I add an whole little chapter for it! For you! This is the item you want if opponent spam armor! (Or just buy it "beacuse"), This will give you a ****load of armor penentration and attack damage! If you feel scared of the 5k-hp Rammus or the trolling smurf with double Guardian Angels buy this! (insted of your boots) Or intead of the life-steal if you just carry the game apart and no-one have a chance against the GLORIUS Kog'Maw! (if you use this build!)
