Skarner's ultimate, Impale, allows him to basically grab an enemy and freely move around, dragging the enemy with him. But what happens if Skarner performs a Flash during this time?
Similarly, I'm assuming that using Ghost during this time would allow you to drag the enemy much further.
Obviously, this should be pretty easy to determine, but I don't have Skarner (nor am I interested in purchasing him at this time).
