Hello, I've seen the new slot system which now uses datapacks but when I want to add 2 ring slots the game only displays one:

{
  "entities": ["player"],
  "slots": ["ring", "ring"]
}

That's the entity configuration file, which is only for giving already registered slot types and doesn't stack like that. What you want to do is create a ring slot datapack file and specify "size": 2 in order to change the number of slots for that slot type. I'll update the documentation to clarify this point.

I saw that you what you have added and I understand better the principle thank you to you!
