Wondrous Tails rewards question

Hi, im a lucky new player and I just got 3 lines in Wondrous Tails.

However im not lv 80 and im interested in getting a gold certificate, I have 10 days left until my Wondrous Tails expire, do you know if my rewards will change if I level to 80?
Or it wont update rewards until the next Wondrous Tails?

Thank you ^^

the book you get is snapshot to your level when you pick it up. levelling to 80 won't change the rewards unfortunately. you're out of luck.

sad, okay ty ;(
