It's almost been 40 days that I had gotten a Gold World pass for my friend, so we can almost get the guide beret About one more week to go.
And yes, you need to be in a pty with the one you got the gold world pass for or who got it for you. The first day you can get a stack of Choco passes, then 40 days later you get a guide beret, then 100 days later you can choose out of a list of items, then 365 days later you get a model airship for your MH.
