How about "attack of will" against spirits in SR5?

Is it gone or not?

If not, where can I read about it?

And how does it function against Materialized spirits Immunity To Normal Weapon?

(I think my players would really like to know for our next session...)

A.

This is now in one of the martial arts techniques in Run & Gun. Don't remember the name. It is one of two that are in special side bars, and are available for all martial arts.

It's called Neijia, and any character that has purchased a martial arts style can learn it.
