Help with scriptableobjects

I tried to ask this question a while ago but as that got no answers, I’m going to try to rephrase it.
I’m creating a fire emblem-style strategy game and wanted to know what the best way of storing character stats (Ally or enemy).
Originally I was going to use scriptable objects but I read that they don’t work for saving things in deployed games so they wouldn’t work if someone levelled up or a weapon’s durability needed to drop.
Am I misunderstanding this? If not, what other methods could I use for storing this data? Thank you for any help that you can give.

You´re right scriptableobjects reset them self, whene a game build gets booted, but you can safe theire data to a text file and read them on start. Brackeys made a pretty good video about such a save and load system: SAVE & LOAD SYSTEM in Unity - YouTube
