Not Updated For Current Season
Alright well this is one of my first builds on Mobafire so i hope you guys enjoy.
This build is pretty straight forward but it will definitely ensure that you will kick some *** in every game. When you start the game you ALWAYS want to get mid, this will help you because you want to rush your Caustic Spittle giving you massive attack speed. When you start the game i usually start with a Dorans shield because i really like the health regen but it's completely up to you, you can use Dorans Sword or Shield, either way works fine. Once you're in mid you will want to stay in the lane till you usually have enough for your basic boots and the first two items to Phage, and hopefully enough to even buy the recipe. Sometimes the lane can be very aggressive so you have to recall sooner than you would have wished to, if this happens buy as much as you can but make sure to get the basic boots so that you have the movement speed over the other mid, and buy some health pots or a health elixer on your way back.
When you get back to your lane you want to get phage as fast as possbile because you will completely own them with Bio-Arcane Barrage, making it so phage slows them. Don't be too aggressive till level 6 when you get your ultimate, Kog'Maw doesn't have a very good early game so if you're being too agressive the other mid can probably kill you pretty easily. Once you have enough go back and finish phage and your upgraded boots, if both are already finished then get started on your bloodrazer. I rush the Recurve Bow as soon as possible so that i get that extra attack speed, than slowly get the attack damage items.
Now is when you start rolling and you will be owning everybody. Once you finish bloodrazer get another attack speed item, as in wits end, sword of the divine, starks fevor, or last whisper, this will depend on the teams composition, i usually get wit's end because the other team is bound to have an ability power user. After this you get your black cleaver, this will make it so you completely crush your enemies. At this point if you have already sold your dorans shield it is fine. I usually don't get rid of my dorans till i have too becasue that extra 120 health is just fine and why sell it unless you have to?
By this time it should be gg because you are killing them all to fast and they should be qqing and surrender. If not then finish your phage so that it is a frozen mallet. If you are having trouble with survivability still then you should get a guardian angel, or banshees vail or whatever item you need to help you survive, again this all depends on the other teams composition.
With this build you should be pwning noobs all day long! I hope you enjoi.
P.S. if you ever have any ingame questions add Zethroc and ask me anything.
