Marriage in Vana’ diel is to declare devotion and show commitment to each other. As a proof of the vow, generally wedding rings are exchanged.

When getting married, the adventurers can receive a marriage certificate from Wedding Master NPC in the game if they wear their Matrimony Rings or Bands. Also, various wedding items such as Matrimony Rings or Bands, wedding costumes, and items to change the BGM can be purchased from Matrimonial Coffer and Celebratory Chest.

Basic wedding flow is as follows.
Walk down the ceremony aisle → Make vows → Exchange the rings → Marriage certificate is issued
