Everyone loves to celebrate their birthday, and the characters in Genshin Impact are no different. Each character has their own special day of the year when they get to celebrate the eternal passage of time. The only person without a set day is the Traveller, as you set their birthday yourself when you create your character.
On a character’s birthday, you will receive a mail from them that contains their Special Dish, and some form of Ascension material. On the Traveller’s birthday, you will receive a cake that can give you a piece of Fragile Resin.
Thankfully, you don’t need to own the characters to get their message on their birthday, but if you miss the log in that day then you won’t get the mail at all.
