Immolation on Enemy

I've created a custom Immolation spell called Circle of Fire but I'd like it to be able to target Enemy units, and decrease their health for as long as it burns.
I don't think it's possible to edit a spell so it gives a target, so is there way I could use another effect spell I could use and make it have Immolations graphics? What would should I use?

I've seen screenshots of the World Editor where you can specify a path name in the unit editor, I normall have to use W3U edit to do this. How can it be done?

Maybe theres a way to make lightning shield hurt the person it's cast on only. Give it a shot?

If you want it to just hurt the targeted unit then a life draining spell like unholy frenzy could work (make sure you set the addaed attack speed to 0) or you could use rejuvination and set the amount healed to negative. Don't think theres a spell that will hurt the target and the surrounding units tho

Ive made a spell like that... its easy, you make a poision type spell, change the graphics on it be be the immolation... simple as that!!!

i personally think that the unholy frenzy idea is the easiest to do

wut r u gonna use this spell in?
