How to get an instance of a custom damage type?

In my weapon class I have the AddPointDamage node which requires a damage type, a purple “class” typed variable. Alright, I pass one of my custom damage types. However I’d also like to access data in that custom damage type but for that I’d need an actual instance of that class, a cyan thing. How can I make one? It’s not an actor so I can’t spawn it. One such instance gets passed to the damaged item’s damage event but I want to have that here, in the damage causer.
