With this build you can just spray and pray as Kog'Maw does. THIS IS VERY IMPORTANT!!! You need to have the Prehistoric skin on. Why you ask? That is a secret.
By the end of this build you will be dealing nearly 600 Crit damage per auto against players that haven't built to counter this build and around 300 to players that have. You also have 100% crit chance so you will melt any champion (unless its a Dr. Mundo because he just doesn't die).
To play with this build you need to be in the action at all times. You will have to dive into the entire enemy team and activate all of your abilities on everyone. You need to dive WITH YOUR TEAM though or else your done. You are still pretty Tanky but still. Better safe than sorry.
Hopefully this build serves you well. Please like if you love the build. Comment what can be changed for the better in the build and give me some feedback on this guide.
And as always:
/all gl hf :D
