Question Set an array of spells in a ScriptableObject

Hello everyone,
I have a scriptable object that i use to create weapons.

Code (CSharp):

1. [CreateAssetMenu(fileName = "New weapon", menuName = "Weapon")]
2. public class WeaponData : ScriptableObject
3. {
4.     public string name_;
5.     public Sprite sprite;
6.     public bool ranged;
7.     public int energy;
8. }

I try to give each weapons 1 to 25 slots. In order to set spells in these slots.
I think the best solution is to use an array
My problem is that i don't see how to do it.
Can you help me?

 

Code (csharp):

1.  
2. public SpellData[] spellSlots;
3.  

And then drag and drop the equivalent spell SOs in the inspector?
