How To change the 3DstartRotation of a ParticleSystem, using another GameObject Rotation?

I'm trying to cast a skill in my game So i created a particle system , enable the 3DstartRotation(becauser the particle was not facing the correct direction), and adjusted the y to be 90°

But, when i instantiate the particle, that is c$$anonymous$$ld to a EmptyGameObject, called spell, she did't chance $$anonymous$$s rotation.

I tryed

 public class ParticleRotation : MonoBehaviour {
 
     public ParticleSystem t$$anonymous$$sParticle;
     public Transform shotRotation;
     void Start () {
 
         t$$anonymous$$sParticle = GetComponent<ParticleSystem> ();
         var main = t$$anonymous$$sParticle.main;
         main.startRotation3D = true;
     }
     
     // Update is called once per frame
     void Update () {
 
 
         var main = t$$anonymous$$sParticle.main;
 
         main.startRotationY = Mathf.Deg2Rad*90 + shotRotation.transform.rotation;
     }
 }
 

But did not work so, in simple words, i just need to cast my Spell in the direction that my player is facing. And because my skill have a t$$anonymous$$n look, i need to change $$anonymous$$s in some way.

ty for the help. Sry grammar.
