Graves Ability (LoL): Smoke Screen

Graves fires a smoke canister at the target area, dealing 60 / 110 / 160 / 210 / 260 (+60% of ability power) magic damage upon landing and creating a cloud of smoke 675 units wide for 4 seconds. Enemies inside the smoke cloud will be slowed by 50% and will have their vision reduced to only what is inside the smoke cloud. The slow lasts for 0.5 seconds after the target leaves the cloud.
