radial damage with other shape?

Ive made a weapon in UE4 with line trace that does radial damage. But I want the radial to be shaped in a particular way. Is it possible to change the shape of the “sphere” or “radial” that deals out the damage? So that it works like the flak cannon in unreal tournament, but with much different behavior. If someone can tut me it would be great! Or point me in some direction. :slight_smile: maybe something to do with Cones?? i am complete noob! begun with unreal just days ago.

image of what i want to go for. it is picture of how it would look like from above and from the FPS perspective.
