Help with Shuriken Storm ability (channeling spell)

[RushHour1049]

I'm trying to make a triggering spell called Shuriken Storm. One casts Shuriken Storm on a point on the ground (or an enemy), and what should happen is the casting hero faces a direction that is targeted, then he channels for one second while he throws 10 shurikens in that direction that go for a certain distance. The first thing a shuriken hits takes damage.

Now I've thought of two ways to trigger this spell.
1) When the hero begins channelling, a dummy unit appears above him that periodically summons shuriken units that go hovering in the direction of the spell. Then there would be some other trigger that says "if the shuriken touches a unit" or something, then that unit takes damage.

2) When the hero begins channelling, a dummy unit appears above him that launches projectiles of some kind that look like shurikens. Then I could somehow modify the attack so that it stops when it hits an enemy.

I have two questions: which one of these ways is better? (or is there an even better way?) and then how do I trigger the best way to make this spell work?

I tried to make that ability under the same name for my map, darn you! Anyway, what I think MIGHT work is to activate the stampede ability except replace the Combat Model with Huntress (Naisha) Unit Missile. Wait a sec... I think I'll try that now...

OMG!!!!!!!!!! That works!!! Just make it stampede, change the lizards into shurikens, and make the width of the stampede like 50 instead of 700 or whatever. Thank you!!!!

Problem not solved!

Sorry for double post, but the stampede idea doesnt work. Like UnkowVector said, there isnt a way to make the shurikens go in a line.

So the problem still need solving folks: how do I trigger the spell?
