This is my first Kog'maw build, well my first build here to begin with. This is a work in progress and as I learn and play more as Kog this guide may change.

Kog'maw can be played many different ways. This focuses more on AS/AD with options of going with a hybrid build.

Recommended Runes

For runes, I use flat armor seals , flat magic resist glyphs , armor pen marks Greater Mark of Desolation , and move speed quintessences .

I choose these because Kog'Maw isn't very resilient. If an enemy gets upon you, chances are that you won't live past it. I get move speed quints because Kog is a relatively slow champion and this can help you get back to your lane to continue farming or get to the team quicker for a team fight. This is just my personal preference but I think that survivability and move speed on him is very useful.

Alternative Runes

If you want to focus on increasing the magic damage portion of your , a few good options are

If you want to focus more on the AD aspect of Kog'Maw, use the Recommended Runes instead, swap out your Marks for and your Quintessences for These will not only give you a good portion of AD but will also make it much easier to farm CS and get your items that much quicker.

I am going with a 21/0/9 build picking up move speed in utility and neutral buff duration. Kog'Maw with any sort of Buff (Red or Blue) can be very scary for your opponents.

In offense I pick up for the most part all of the AD masteries simply because your main damage comes from your W aka autoattacks. Once again as personal preference I took havoc over sunder because you are doing more than just AD as Kog.

I typically start kog out with and x3 or and x5. It really depends on who you are going to be laning against as to which you should choose.

Overall my first two items regardless are and . I get Madred's because the key being successful with Kog'maw is farming minions and the proc from Madred's can almost instantly kill a minion. Plus you get added AD and armor for your survivability needs.

At this point I will pick up a to boost your mobility and attack speed as well as for the same reason.

From there I build my and . Once you get these items, you will start literally shredding everything apart that you come in contact with. Plus they both give you a good amount of attack speed. Remember, keep farming with your Madred's. These will only help speed up the process and make farming much much easier.

At this point, depending on how the other team is building, you have the choice of finishing your Madred's into a (if the enemy team is dropping like flies to your awesomeness) or if they are building more MR you can build your . Both items give a substantial boost to your damage output.

By building both of these items, the enemy will have a hard time countering you as a carry since you will be dealing a lot of AD with and heavy magic damage through your W and .

Lastly, finish your and watch everyone fall to your awesomeness.

Alternate Items:
if you're in need of that lifesteal to sustain your survivability.

My personal preference is You get spell vamp as well as lifesteal and your AP and AD increase a decent amount making your abilities that much more potent.

If you're finding that you're dieing a lot and need survivability, you can pick up a . If that isn't enough you can pick up a

If you wish to focus more on his AP qualities is a good option as well.

Personally if you do wish to swap out items, I would replace either the Wit's End or Malady for the other alternate items. You need your to do the most damage.

More updates to come.

Upon dying, Kog'Maw starts a chain reaction in his body which causes him to detonate after 4 seconds, dealing 100 + (25 x level) true damage to surrounding enemies.

Kog'maw can move freely while this is active. This is a great ability to use to help damage your opponents after you die which may turn the tide of a team fight if you use it successfully. Ultimately you don't want to rely on your passive to damage the other team, but if you do end up dying, take chase to enemy champions!!! Stay behind your team and you should be fine.

(Passive) Permanently increases Kog'Maw's attack speed. Upon activation Kog'Maw launches a projectile at a target which deals magic damage and reduces its armor and magic resist for 4 seconds.

I pick up Caustic Spittle second because it's very useful for helping to last hit minions or if your misjudge how much your attack with hit for, you can finish it with this ability. Plus it gives an attack speed buff to you with each level. Max this second.

For 8 seconds, Kog'Maw's autoattacks gain great range and deal additional magic damage which is equal to a percentage of the target's max health (6% at max level) Increases by 1% per 100 ability power that you have.

I start out putting 1 point into Bio Arcane Barrage first because it is the bread and butter of this build. You get amazing range with it and it adds damage to your autoattack which helps you farm easier as well as lets you harass an enemy champion from a much safer distance. With this and your Bloodrazor you will be dealing 10% of your enemy's health as damage per hit. Max this first! It is your main damaging ability!

Kog'maw launches ooze which deals magic damage to enemies that it passes through. It leaves a trail which slows enemies for 4 seconds.

The slow is alright at best. It's very easy to dodge if you're in a lane. It doesn't do a significant amount of damage either. A good use for this ability is if you are ganking someone, you can use it to block their escape path or to slow them enough to allow your teammates to catch up or safely time your Living Artillery.

Kog'maw fires artillery from a great distance. After a short duration the artillery falls dealing a portion of your AD and AP as magic damage. It deals 250% bonus damage to champions. Each subsequent artillery in the next 6 seconds costs 40 additional mana, capping at 200.

Living Artillery is one of the best Ultimates in the game. It allows you to poke from a very far distance, it does a lot of damage and is nearly spammable. This scales from both AP and AD. Be careful and watch your mana closely otherwise you will run out very fast if you're careless with this ability. This ability takes some getting used to when you're learning how to play Kog'maw. it is delayed before it actually hits so you will need to lead with it or guess where your opponent will be when it lands. You can also use this to check bushes and the jungle without putting yourself in danger. This reveals the area and champions it hits for a short time making visibility better for your team.

Summoner Spells

Kog'maw doesn't have any real escape options or abilities.

in my opinion is a must for those dangerous situations where you may be out of position and get charged. This can also save you from an overly aggressive laning opponent.

is for the added mobility. This is mainly optional but can be very helpful to outrun your opponent or chase them down.

Other choices are:

clears CC. Need I say more?

can save you from a champion who strays too close or can slow them down enough for you to melt their face off.

not a bad option if you have a support with you who doesn't heal (Nunu comes to mind. Can be very helpful laning with his slow and his buff) This is really the only time I would use this. This spot can be filled with other options that benefit you in other ways.

works well with Kog'maw. It gives a good attack speed boost and some added AP which can help you when going into a team fight to get to the next 1% mark with your Take this if you need more offense but I personally feel that this spot can be filled with something more defensive.

Ultimately, there isn't a 100% set way to build Kog'maw. It's all about testing new things because he is a champion who can be built many different ways. This is how I play him and how I enjoy playing him.

Let me know what you think and any thoughts and input is very much appreciated.

More updates for gameplay will be upcoming.
