Loop a spell

[Kabel]

I have a unit that casts Impale. The spikes of impale are replaced with flames.
When the spell is casted, it looks like a wall of fire shoots out from the caster.

I wonder how to make a spell "loop"?

That means that when Impale is casted and finished, the caster casts it again and again until it is ordered to move or stop.

Well, you will make a channeling spell, based off "Channel". You will use Art - Follow through time to the amount of time you want.
You will then make a dummy unit and an Impale spell with the flame model you want. Give it a cooldown of 0 seconds.
