Arrow Shower skill

This is the spell i need: The hero shoots 9 arrows that damages an area.
Sounds easy? yes thats what i thought... First i tried basing it of fan of knives but that didnt work because i dont get too select where the spell is supposed to appear. Then i tried basing if of Blizzard but then i couldnt change the graphics. Can someone please help me with this?

I'll create a map for you that shows you how to do it.

Can you help me with a big trigger project problem im having. I would explain it, but its really confusing. Do you have AIM?

If you use any, give credit to me.
