What is Critikill Kog'Maw?

Critikill focuses entirely on a critical strike champ build. When this build is complete, you should be doing over 2000 damage every second to most champions. That is sustained attack damage, not a burst. And while that damage isn't the highest AD you can achieve on any champion, Kog'Maw has the largest attack range of any champion when



This is a long-range high damage build. It relies heavily on the range of
Bio-Arcane Barrage,
Void Ooze and
Living Artillery to punish your opponents while not allowing them to come within range of you. Keep that in mind, you should almost never voluntarily get within range of your opponent. Be careful about attacking without Barrage on, as you will be putting yourself at risk.
In the lane phase you are a harasser - one of the best in the game. You can keep some of the strongest champions in their place by forcing them off of minion farm time and again with
Bio-Arcane Barrage, by using
Living Artillery to whittle away their health or strike them when they are nest to a turret, or by placing
Void Ooze so that they have to run around or get severely slowed. If they ever let their guard down and get too close, Kog can run up just a bit and PUNISH them for being too aggressive.
With all this in mind - you are squishy, and if you are playing him solo-mid (this guide works quite well for most solomid) you have to be extremely cautious. Place plenty of wards and use
Void Ooze and
Flash/
Ghost to escape your opponents. If you remain aware of the battlefield, you should have no problem escaping gank attempts and punishing their gankers for even trying. When escaping, dont forget to kite your opponents whenever possible. Your high crits and lifesteal mean your opponent can go from chasing you to dead really quick, and you'll be back at full health standing on their corpse.
Another note: Critikill is a high-success build. It REQUIRES heavy early-game farm, a few early kills and a low early death ratio. If you get into a game and you can't farm gold well for whatever reason, you should have a backup build ready. I will work on adding a backup to this guide, but until then Mowen's Right Click and Win is a good, slower paced alternative.

The skill sequence is simple: get a point into
Void Ooze first to prevent early game ganks and gives you some quick lane control. I have gotten many level-1 first bloods by simply using void ooze and attacking as quick as i can. After that, Void Ooze will max at level 13, mainly to increase the slow.
The first skill you need to max is
Bio-Arcane Barrage. Each level extends its range, increases its damage, and makes you more and more powerful.
Point 4 goes to
Caustic Spittle to get an attack speed boost early and to allow you to cause a little bit of armor reduction. Then ignore this skill until the very end unless people are often getting too close or you are unable to land your Void Ooze marks and the AS would be more beneficial.
Obviously, take
Living Artillery at 6, 11, and 16

Again, critikill focuses heavily on critical strikes and critical strike damage. Note that by the end of the build, you will literally crit every single hit for 260% damage. This is turning critical striking from getting lucky hits into making it part of our standard damage, and the effect is brutal. In order, we have...
Boots and triple
Health Potions is my favorite start. Kog does better with the early game movement speed: it secures more kills and makes it far easier to escape nasty situations. You will need to remain as fast or faster than most opponents all game - start now.
Doran's Blade provides a decent damage bonus, a small vamp, and a bit of bonus health, all great early game as with any Doran's item. However, I only get this item if I am having difficulty in lane. DO NOT go back for it if you dont need it, stay in lane and farm minions instead.
Berserker's Greaves gives a little early game attack speed, allowing you to start seeing some real damage from
Bio-Arcane Barrage early. Again, you need to be faster than your opponents anyway - get level 2 boots first.
Vampiric Scepter is what gives you some early game sustain. Even with this in hand, you should still buy a few pots to keep yourself in the fight.
Bloodthirster I am usually able to sustain in lane for a long time with just the vampiric scepter and some smart play, until i can farm up enough gold for this Bloodthirster. Consider going back at the BF sword mark to greatly increase damage.
Zeal gives movement speed, attack speed and is your first critical striking item. Get it next to keep yourself quick.
Infinity Edge should be an obvious build choice. The bonus crit damage is beautiful, the bonus damage is beautiful, and you need the crit chance.
Phantom Dancers speeds you up again and further increases your critical chances. You should have this before level 18, and it will ake you have critical strikes more than half the time.
Black Cleaver drives your attack speed up further and deals with your opponents who should have started building some armor to counter you. When this is complete, you can easily bring down baron with the aid of a decent tank.
Phantom Dancers is important for the exact same reason it was important a moment ago. You should be flying across the map by now, very difficult to hit and very difficult to escape as well, with constant critical striking
Trinity Force I usually get last as it is expensive and not core to the build. However, everything about this item is useful. It exactly brings your critical strike chance up to 100%, it allows for nice damage bursts following skill activation (which means that your first hit after using
Bio-Arcane Barrage is sickening), it provides some movement speed as compensation for selling off level 2 boots, he slow is useful, the AP is useful, the AD gives a nice bonus, you get a little more attack speed. However, if you were to remove one item from the build, this would be it. Either keep the boots or...

No question, for this build, BC wins.








Note that both of my Default spell choices are benefitted by choosing

Alternative Spells








Mowen
A tip of the hat to Mowen for the current top Kog build Right Click and Win, which is what started me on AD Kog. This build is similar but focuses more on critical strikes and truly bringing out Kog'Maw's damage potential. I highly suggest looking to his guide for extra playstyle tips if you are just learning to play Kog.
Astral Yorae
Astral's damage calculator was utilized for all the damage calculations listed in this build. While I believe he is still adding to it, it is already by far the most complex and accurate damage calculator I have found anywhere. You can get it here.
