|“||This is a special person with diplomatic importance. Anyone who attacks this guy will be in serious trouble with his faction.||”|
Diplomatic Status is given to a person with high importance in a faction. Attacking or disturbing such a person can lead to a great amount of trouble. In practice, harming them or imprisoning them in any way will severely damage their faction's relationship with your own, but healing them if they're injured is a quick way to get in their good graces. This also applies to other factions, and can lead to conflict if both are present in the same place after such an incident.
NPCs that have Diplomatic Status cannot be targeted by ranged weapons.
Faction Pacifiers also have Diplomatic Status.
