Assing any variable to another variable in inspector

So basically I want to make a list which changes any variable by any amount. I want to be able to do this in the inspector.
I am making an enemy and want to make a list which only activates when certain difficulty level is chosen. This list will change certain enemy variable to make this enemy easier to deal with. And i wonder how to make it easily accessible to change in future.

Thanks in advance.

So many ways to do this, a scriptable object is probably the best way, but you could make some manager script as well… Any data you want to change you put it in a scriptable object, I’d call it Difficulty, and you create different instances of the scriptable object for different difficulties, then where you want your variables to change you take out those variables and replace with a reference to the scriptable object and use the variables from scriptable object.
