Nether Realm Suggestion

Have a rare Nether Stone Forge nether realm, where you can choose a trait, and have a nether stone generate with that trait guarantied.

A frequency of maybe once every 50 to 200 realms might work?

Honestly, as a slow player myself that might get through a small handful of realms a day and finds 50 realms a hell of a milestone, I’d say that’s too frequent. 500 might be a good call. That’s a mad powerful thing to have access to.
