Casting Frost Nova with a dummy - target problem.

Ok so I want to make a spell that fires 10 Frost Novas in a line.

Now the problem is that frost nova must have a unit target,
so I basically need a dummy target for a dummy caster.

I tried having dummy casters cast nova on themselves but it does not work if casters are locust. (I can make it work if they are invulnerable)

Now having non-locust dummy casters is a bad idea,
so I thought I simply make dummy targets that are with no model and invulnerable but then I have same problem again.
What if dummy targets interfere with some other stuff because they are not locust? What if dummy targets get killed or moved by some other triggers?

I am going in circles here, any ideas?

Wait what triggers do you have that could possibly move your invisible invulnerable non-locust dummies?

You can move any unit with jass provided that you have it's handle, it does not matter that is invulnerable or anything.

Does anyone know how to properly do this frost nova stuff?

Is there some way you can create the frost nova effect and play the sound at the point, and trigger the effects (since its in a line I'm assuming you don't care about primary target damage and such, you just want the AoE damage & slow?)

How bought using the instant cast method (unless you are already doing so; search 'amov' ) and then create your dummy unit, cast upon it, and then remove it instantly (without any breaks).

You know the ability 'Impale'? Change its animation to frost nova, and replace the stun anim/buff with a frozen anim/buff. It works beautifully without a single trigger.

You can still cast spells on hidden units as far as i know.

This may be the dumbest idea you'll ever hear, but how about creating dummy units with an attack AND the frost ability. Order the units to attack ground and then poof, you got your dummy spell.

I already did so, but I don't like it because I had dummy recycling and now it is useless because I remove dummies.
(btw instantly removing dummies after you cast stops the spell,
the right way to do that is to add them 1.0 sec generic expiration timer)

Did not find that thing 'amov' what ever it is.
Is that supposed to be an ability?

To all who proposed to "fake" the frost nova spell:
This was not strictly about frost nova, there are other unit-target spells
therefore specific solutions don't do it for me.

Vex's CasterSystem does not use 'Aloc' and it does not have any problems at all. If you are enuming units you can simply check if it is a caster unit.

So just create one caster, move it to a location, make it cast frost nova on itself, rinse and repeat.

It is using ghost(visible) ability.

I wonder if ghosts get picked up by groupenum functions...

You could take away locust, make them cast it on themselves, and then add locust to them again. Or just make it so the frost nova kills them.

caster system uses Aloc...

I have a spell called ice wave. What I do is mostly make the caster target itself, I think I remove Aloc and add it later but also make it invulnerable or something like that, if I remember correctly I rely on secondary effects from Aloc that remain even after you remove the ability.
