The Age of Wushu site has been updated with a new developer blog that lays out the details of the relationship system. Players will be able to form bonds with others in any one of several ways, from spouse to friend to blood enemy and more.
These relationships have their own functions, some even have their own metrics. Friends and Close Friends are measured by Intimacy, while Enemy and Blood Enemy use Hatred. Sending gifts and teaming up for instances increases intimacy, just as Kidnapping and Killing players increases hatred and reduces intimacy. Making an Enemy is a one-sided affair. After a player is killed, they can add someone to their Enemy list. Players on an Enemy List cannot join in teams or receive gifts from the person that added them to the list. However, drinking Friendship Wine together can help resolved differences, and allow players to bond once more. Any further killing only deepens the animosity between players until they become Blood Enemies.
