50 is the radius of Karthus' Lay Waste; 75 is the radius of Cassiopeia's Noxious Blast; and 200 is the radius of Xerath's Arcane Barrage. The channeling time would be maybe a second at most. It's to feeling like you're refining the lightning bolt - more precise and more damage. If people can his Karthus' Q, they'll have no problem with this guy.

I don't know how to handle the channeling actually. Maybe it should just be a charged ability, like Varus and Vi, and he can still move. Maybe it should be smart-cast by default and it'd literally be a Karthus Q that you can hold the button down to make it deal more damage.
