Passive: Icathian surprise: Upon taking fatal damage, Kog'Maw remains active for 3 seconds, becoming pacified, invulnerable, untargetable and gaining up to 50% bonus movement speed over the duration. He then explodes, dealing 175 − 600 (based on level) true damage to all nearby enemies.

What did I change?

1. I made kog'maw's old E into his new Q with changes to make him deal more hybrid damage and gain slightly more range. I also put his old Q passive onto this one.
2. I made a new W and E because I think these would better help kog'maw. Plus they play a part in what I think could be part of kog'maw's lore.
3. Kog'maw's ult now deals bonus damage if the target id above or below 50% health. I did this to make this ability not only a good fight ender but a good fight starter.

Lore: I don't know much about Kog'maw's lore but my new W and E are supposed to represent how I think kog'maw should have the ability to change the temperature of himself and the environment around him.
