So, what I'm after is this.
The unit casts the ability, he gains some holy aura around him(SFX) it lasts 15 seconds. During those 15 seconds, any unit that comes within say, 500 of the hero, is struck with a holy bolt at 3 second intervals, creating a special effect at the location of the struck unit. It's not a channel spell, so the hero would be able to move around while it was active.
Any help would be more than welcome!
Edit: I'd assume you'd need to have two spells, and two triggers. The first spell would activate the first trigger, which would create a dummy unit, who'd then cast the spell at any enemy within 500, checking every 3 seconds. I'm still not really sure how to trigger this.
