Spell project art, does it even have any?

I am trying to make a gernade spell, but does instant damage like fireball, and NOT like Firestrike. So i got that part, used Blizzard with one shard/wave, but there are no projectile art. I need a model from the Unit to the area i selected for the spell. I tryed everything, does some spell not have one? Then how would i do it?

THanks.

use the tinkers rocket missile spell for a projectile alongside an area of effect attack
