Splash Damage With Spells

I've already got most of the spell to work. What happens is, you use the spell and you target an enemy unit. the hero launches a projectile into the air. it has an arc of 1, so it dissapears for a sec. Then it comes almost straight down, damaging the unit it lands on. The only problem is, i want it to hurt a lot of units, with a big splash damage. and instead of targeting just one unit, i want it to have the targeting thing like in blizzard. I've tried to do it with blizard, but i only want 1 projectile coming down, and as far as i know, you cant easily change the blizzard animation.

Also, i wanted to know if i could change the projectile size. I know it would change if the hero's size was changed, but i only want the projectile size to change.

I could probably do this with triggers and stuff, but i wanna know if i can do it without. Plus, im too lazy. :ggani:

What about using the infernal spell?

How about making the spell summon a dummy, transparent unit with no collision that has the attack? That way you can easily scale the projectile size and give the ability direct splash damage (use the Spells damage type). Then give it an expiration timer and the Unknown (Aloc) ability. Should work if you have scale projectiles on :D

a unit with no collision causes server split, I wouldn't recomend doing it.
