Kog'Maw... What can i say.. according to his cons, he doesn't have many escape options, but he wont be the one trying to flee. With the combination of his Caustic Spittle, Black Cleaver, and Stark's Fervor your opponents armor will be a fading memory. 400 attack damage, almost max attack speed, and Madred's Bloodrazor nothing lasts long. If they do get out of your range slow them down, with either void ooze or pop your bio-arcane barrage and if that doesn't kill them, your Frozen Mallet would have slowed them down enough for you to easily finish anyone off. Playing Kog'Maw has been a highlight of my LoL experience, and with this build I hope to bestow upon you the joys of what is known as... Kog'Maw: The Mouth of the Void
