[Spell] How to make blizzard/rof without channel

[sethmachine]

Hi,

What is the standard way to make spells like Blizzard or Rain of Fire without channel, e.g.

if a hero casts channeless Blizzard, it acts as a single cast AOE spell that does blizzard for the max number of waves (so the hero can move, cast other spells, etc., and stunning does not stop it unless they r stunned right as they cast it).

A unit starts the effect of the ability

Create a dummy unit with a dummy blizzard ability and make it cast is on the initial targeted point.

Another way would involve a periodic trigger, a unit group, a integer variable to keep track of waves etc etc.

Would it be possible with no dummy unit and no triggers (an object editor solution only)?

I don't think so.
The essence of a channeled ability is that a unit channels it, and thus must be occupied by that action.
I can only think of aura based abilities that are kind of channeled without actually being occupied by it.

So I don't think it's possible to make a Blizzard-like ability that keeps casting waves at a point while the caster moves away.
