Build Guide by AtIass

Explanations

Runes Explained-

The runes are all runes of alacrity for the reason that KogMaw can have the fastest attack speed in the game with this build, runes, and his passive caustic spittle. Now what i do need to say in here is that Kog does have low health so sometimes i use Quints of fortitiude instead if desolation WHICH can be useful. Also Sometimes i use alacrity marks and it seems benefiting to attack speed items.

Masteries Explained-

I use flash to chase down enemies who just happen to get out of the range of my bio arcana barrage once i get into view of them i use exhaust to slow them and finish it off with living artillery/bio arcana barrage.

Items Explained

Berserker Grieves- Now i am a man who enjoys shoes early on so i tend to always get these first. Though i do know that buying a zeal first also works really well and i have personally found it very useful, but i prefer the berserker grieves early on for the extra attack speed and the movement never hurts.
Zeal/Phantom Dancer- Now i always get a zeal then go back for the phantom to me it makes more sense than saving up 3k. I think buying a phantom dancer early gives you an edge because it gives you great assets. Once again i am a guy who never thinks it hurts to move faster so the extra movement speed always makes me jump for joy. The attack speed it gives you should make you be able to finish off most champions in the League of Legends considering they have not been fed. The Phantom dancer fused with Bio Arcana barrage and Caustic spittle early on can be devastating to enemy champs.
Madreds Bloodrazor- I personally love this item. When using a champ thats focused on attack speed like KogMaw the damage every hit is extremely helpful since you have no dmg items early on.
Sword of Divine- By now you have around 2 attacks a second and you get 100 extra magic dmg every 4th hit? thats every 2 seconds you do 100dmg not only that but your attacks cant be dodged so enemy champions like jax will also die. im not one to say things to make myself feel better but thats pretty awesome right?
Phage/Frozen Mallet- Ok By this item its late game. In late game when using KogMaw the big thing is his health. He doesnt have very much health so you need an HP item. This is where i think Frozen mallet is the best. 700 health and your attacks slow enemy champs....also the 20dmg doesn't hurt.
The Black Cleaver- I love the idea of reducing someones armor so i picked black cleaver over bloodthirster. it gives 75 attack dmg and is by far one of the best items you can get while playing kogmaw. I put in as the last item but depending on who your fighting (i.e. Sion,Mord,and Allistar) you might want it before sword of divine.
