Leave a burning effect (visually) in the area it landed for a few seconds, which damages people who stay in it over time. A slow might be too much, but the burning effect would be a perfect addition to Ziggs' kit.

I mean really, when you think of inferno, you think of fire, right? Why doesn't this ability set things on fire like the name heavily implies?

Bump

That would be pretty cool, but it would also be really strong. The initial damage would have to be nerfed to compensate for sure, and what about the unique way the AoE works, making the center more damaging?

I agree. Ziggs has been one of my favorite AP carries since his release and I just feel he could use some attention, he has a good kit and all, just some good buffs.
