Stop unit from playing cast animation?

I want my unit to cast spell instantly, without any animation and stuff.
Ideas?

There are a few spells that do this. The only one I can think of off the top of my head is Summon Spirit Wolves.

You might be able to stop the cast animation by adding "stand" to the spell's animations.

You can set the spell animations to anything that isn't a name of it's animation. For example, "xomgwtf" or "lol".

If it's immediate targeted to self, Base on Berserk, it doesn't use any spell animations and retains the previous order.

Actually it needs to be autocast ability, but I will try with stand and xasdasd
