We will be using the Relationship rules from Ultimate Campaign. Relationships with NPC will have meaning and building them over the course of the campaign will give you and your fellow adventurers tangible benefits in the game.
You will have 1 relationship point per level you can assign to an NPC of your choice, improving that relationship. Apart from that additional points can be achieved through thoughtful and appropriate gifts, services and other special events related to an NPC or a group.
