Carrion swarm?

I'm pretty sure carrion swarm is a cone, but...that's not important.

In the object editor, change the unit's weapon type to missile (line). Then change the fields Damage Spill Distance and Damage Spill Radius to something non-zero. If it's not obvious, spill distance is how "long" the line is, and the radius is how "wide" it is.

I think carrion swarm is a cone to. But anyways, Ice cones tastes good.

try to use "crushing wave ability", it's just a long straight line damaging 150 AoE, 800 distance.
