Icathian Surprise

Effect radius
◎ 400
Innate: Upon taking fatal damage, Kog'Maw enters a zombie state for 4 seconds, becoming ghosted and gaining 10% bonus movement speed that increases up to 50% over the duration. At the end of the duration, he explodes to deal 140 – 650 (based on level) true damage to nearby enemies.
While under this state, Kog'Maw becomes invulnerable, untargetable, and immune to crowd control, but is also rendered unable to declare basic attacks, cast abilities, use summoner spells, and activate items.
