[Solved] Avalanche - How to stop channeling?

[AtivEnergy]

Greetings!
I found this spell "Avalanche" on a map and i have 2 problems with it..
1. If i cast the spell, the unit remain in a kind of channeling(the green border around the icon) for 3.5 seconds although the spell ends in a maximum of 1.5 seconds.
I just wanted an instant cast like in dota 1, but i still want to see the "spell animation"(if is possible) and only if I move the unit, the "spell animation" should stop.
2. If i put the spell in shift queue, I want it to go like in dota 1.

DOTA 1. GOOD

MY MAP. BAD

The help will be appreciated!


EDIT: I just found out the problem was with my Unit, not with the Spell.
The Art - Animation - Cast Backswing --- was responsible for the problem.

DotA most likely uses a Dummy unit to cast the spell. So Tiny casts a "fake" ability which then fires a trigger which creates and orders a Dummy unit to cast the real Avalanche ability.
