it's just an upgrade

Your method of manipulating the damage and dealing it a distance away will become very difficult.
It's simpler to use line missle as mentioned above.
When the ability is leveled up, increase an upgrade that boosts the range.
This will work (I think) assuming that you can only have one hero of this type per player.
