Storing data (for skills and spells etc)?

advice needed: i am creating a spellbook, what is the best method to store spell/skill(etc) data? so that all my spells-skills are organized into a single file that i can more easily tweak later? i was looking at enums and blueprint interfaces (sorry very n00b here) not sure if those are the systems to use, basically just trying to figure out the name of the system to look into thanks!

You could look into DataAssets. Those are custom assets that you can use to store properties.
