Hello everyone, and welcome to my competitive

As always I just want to point out that this guide will not make you an unstoppable force of power and in no way will automatically make you the best Kog Maw player in the League. However, by following this guide you will certainly become more familiar with Kog' Maw and hopefully will realize his true potential.
Please keep in mind that I did put a lot of effort into making this guide for you, and would kindly ask you for your feedback! If you are going to down vote please at least tell me why in the comments. Thanks!
What is there to say about
Kog'Maw? Well, besides the fact that I call him broken because of the ridiculous damage he puts out, he is a very good AD Carry to have on your team because of the amount of consistent damage he puts out at long ranges.
Playing AD Kog' Maw allows you to do a number of things:

Playing AD Kog' Maw allows you to do a number of things:
- Provide an INSANE amount of damage to all types of champions on the enemy team.
- Harass from exceptional range in your lane with your
Bio-Arcane Barrage
- Provide excellent ganks
- Finish off runners with your
Living Artillery
Although koq'maw dominates late game with the massive amounts of damage he puts out with his items andBio-Arcane Barrage, and the incredible range given to
Living Artillery to easily secure kills and harass players,
Kog'Maw must do well early game. This can be hard considering he is very squishy, and it is hard to escape from tight situations from him.

Situational Spells


I get Heal primarily if I dont have a healing support and their is a heavy hitter or harasser in the enemy lane. (Remember I only know to do this this for ranked, based on viewing the enemy teams AD Carry) It is also nice to pick up if your support does not have a heal and does not take this.


Due to recent use (and thanks to A Chubby Baby for pointing this out) because of













Upon dying, Kog'Maw starts a chain reaction in his body which causes him to move faster and detonate after 4 seconds; dealing 100 + (25 x lvl) true damage to surrounding enemies.
-- A very...interesting and fun passive. Not always useful but you can land a few kills if you barely lose a fight.

Passive: Increases Attack Speed by 10/15/20/25/30%.
Active: Kog'Maw launches a corrosive projectile which deals 60/110/160/210/260 (+0.7) magic damage and reduces the target's Armor and Magic Resist by 5/10/15/20/25 for 4 seconds.
-- An amazing ability for Kog. in addition to your runes the active ability on this gives him more magic and armor pen, so be sure to always start with this and use it whenever possible in fights. The items passive is also extremely helpful, as it permanently increases your Attack Speed

Kog'Maw's attacks gain 130/150/170/190/210 range and deal additional magic damage equal to 2/3/4/5/6% (+0.01)% of the target's maximum Health (Max: 100 Damage vs Monsters). Lasts 8 seconds
-- The bread and butter of Kog' Maw. It increases your range by an amazing amount, and does damage based on the % of their health.


Kog'Maw launches a peculiar ooze which damages all enemies it passes through and leaves a trail which slows enemies who stand on it.
Kog'Maw launches ooze which deals 60/110/160/210/260 (+0.7) magic damage to enemies it passes through.
-- Nice ability, gives you a good slow. Works really well with good positioning.

Kog'Maw fires artillery from a great distance. After a short delay, the artillery falls dealing 80/120/160 (+ ) (+0.3) magic damage and reveals targets for 4 seconds (deals 150% bonus damage to Champions).
Each subsequent Living Artillery in the next 6 seconds costs 40 additional mana (Max 200).
-- One of my favorite ultimates in the game, and we will get into why later. But it is really nice for securing those run away kills, and sniping turrets.
There are many support character in the game that you can lane with and a lot of them are good with Kog. But I am going to list some of my favorites and the ones that I think work best.
Janna
Janna is my personal favorite person to lane with Kog Maw. She may not have a dependent heal, but her
Eye of the Storm, shields you and also gives you a nice damage buff. Her
Howling Gale and
Zephyr are also really good for setting up kills.
While laning with
Janna I grab
Heal as a summoner spell, as she does not have a major heal. Try to get her to work with her to shield you every time you try to harass an enemy, even if just a couple of shots because her
Eye of the Storm increases your attack damage by 14 which can make a huge difference. In addition, set up your viod ooze with her
Howling Gale, this combo is extremely deadly and a lot of the time you will get a kill or they will burn their
Flash if they have it.
Sona
Sona is another one of my favorites. She is consistent with her heals, and her Auras are unmatched. When laning with
Sona there is no need to take
Heal because she can keep you alive with hers extremely well. Her damage Aura is also a very good addition to your lane, helping with last hits and harassment.
Leona
Leona is a good support partner for Kog Maw, she is good at setting up kills, and can take a hit. Her
Zenith Blade ->
Shield of Daybreak combo is a great way to set up kills with
Kog'Maw
Soraka
Soraka is not my favorite but she works. She can help you with your mana if you are in a pinch , and her heals are really great. However, her silence is about the only way to set up kills for you. It does damage and silences them, which is useful, but it has no CC.
Taric
Taric is probably my second favorite support with Kog. He has good heals, a great stun, and his Aura is a really nice thing to have. Not only this but his new ultimate gives you a great attack buff.
Lulu
Lulu, is a very good laning partner. She might not have heals, but she has slows and a shield. On top of that her ulti gives you a significant HP bonus. Not to mention she can also output a bit of damage. Grab
Heal when laning with
Lulu and you should have a blast during your lane phase.

I can get a second one of these for much more life steal.



An amazing item if they have an even more tanky team. Reduces armor like you wouldn't imagine. Replace this with



I am adding this to the alternative items list due to request and further testing. Though mainly for a Hybrid build, replacing this with



These are items that I commonly get depending on the set-up and composition of tmy team and the enemy team.

This is one of my favorite items. It is incredibly useful if they have an AP heavy team, but it also does 42 extra magic damage per attack.

These are the only other boots I buy for kog maw, and I buy them when the enemy team has heavy CC.

A great item if you need some more armor penetration.

Ganking Lanes
Before I explain this I want to say that you will have a MUCH more successful gank if you have red buff. So ask your jungle if you can take it next respawn.
Ganking as

Firstly, you need to know when to gank. You need to know if it is an appropriate situation. Before your gank, observe and ask yourself these few questions:
- How much health do I have?
- How much health does he/she have?
- Am I alone?
- Does he have CC / Can he run away?
- Is it a tank or durable champion?
- Are there any MIA's in the other lanes?
Problem: I have low health and/or low mana, should I proceed to gank him?
Solution: If you have below 40% health I would not recommend engaging a fight. However, if you are not the only person ganking you might consider going in AFTER someone else initiates. If you are low on mana it is usually fine if they are squishy and/or have a low amount of health. However if they have a stun or some type of CC and I would recommend not going in.
When you gank asKog'Maw you have to make sure to do one thing to help secure the kill. When running in shoot your
Void Ooze behind them, NOT ON TOP OF THEM (see tips and screen shots for an example). The first is that when you run in and you try to throw it on top of them, most likely it will end up in front of them based on that they will see you and run back. Not to mention that it will do nowhere near as much damage as if you would slow them and hit them with your
Bio-Arcane Barrage.
After castingVoid Ooze, if you can cast
Caustic Spittle and then proceed to auto attack with your
Bio-Arcane Barrage. If they get away barely, always remember that you can snipe them out with your
Living Artillery.

While I run into their jungle for their red buff, I use my ultimate to check the bush to make sure there are not any enemies. You can do this in many places.

Once again, I was on top of my game this time, and you cannot always expect the same results!
