How Campaign Setting Builder works
Random options keep their current roll until you reroll them. Choose a specific option to hold that value.
Lock protects a field from bulk rerolls. Its own Reroll button still replaces it. A locked dependent blocks rerolling its parent, so world-age details cannot become inconsistent.
Copy creates a plain-text setting outline. Save keeps the current campaign in this browser. Export creates a shareable JSON file using the selected DM access. Backup always includes the full editable campaign. Import asks before replacing current work.
Player-safe files omit DM-only fields and remain view-only after import.
