Playing against Kog'Maw

How to counter and exploit weaknesses

1

Kog'Maw has ZERO mobility — dive him with assassins or engages. One CC = one kill.

2

His W has an uptime/downtime: when W expires, his range returns to normal (500). Engage at that moment.

3

Assassins (Zed, Talon, Fizz) destroy him — he relies entirely on his team to protect him.

4

Buy HP and MR: his W deals magic damage as % max HP, but MR still reduces it.
