Bet the elite 4 and champion.
You can't get an Eon Ticket in Diamond.
Up in my bum
You don't... that's how.Well I gots it
To get to Navel Rock in Pokemon Diamond you need the Mystic Ticket event item. Sadly the Mystic Ticket is no longer available since it was an event item that has long passed.
i don't think you can get the eon ticket in pearl or diamond unless you hack the game, or use action replay. i tried to get it in platinum, pearl, and diamond, but no luck.
The mystic ticket only existed of fire red leaf green and emerald. Basically it is unobtainable in Pokemon pearl diamond and Platinum
all you have to do is beat elite four
Pokemon diamond
Pokemon diamond Pokemon diamond Pokemon diamond
Transfer for ruby etc. or trade with others to increase your chances. Pokemon with different ids must be in your party or it won't matter
You can get the mystery ticket in Pokemon Events. You can get the mystery ticket in Pokemon Events.
