Kog'Maw Passive
I've been thinking about it for a while, and I thought that Kog'Maw's passive didn't really fit him. I have a few ideas for what it could be, but if you guys have any better ideas, please do share;
Want Meat (Passive): Kog'Maw hungers for meat. He becomes more hungry based on how much health he's missing. Kog'Maw gains (0.3% Life Steal) for every (1% Missing Health). Killing an enemy champion heals Kog'Maw by (125% AD)
Void Spit (Passive): Kog'Maw's basic attacks deal (10/17.5/25% AD) bonus physical damage over 4 seconds. This bonus is doubled to (20/35/50% AD) over 4 seconds to enemies below 50% Health. Can only affect an enemy once every 7 seconds.
