The global part of the GO Fest will go live on August 26 and 27, 2023, at 10:00 a.m. local time. Players must purchase the Fest ticket to participate, and the Special Research Task rewards an encounter with Diancie.
Diancie is the Hidden Gems season mascot and debuts as a featured monster in Pokemon GO Fest. The Mythical dual-type monster boasts an impressive stat spread, and players will want to add it to their collection. The fest promises a double debut of Diancie and its Mega-Evolved form, Mega Diancie. Pokemon GO enthusiasts have a lot to play for this August and here’s everything one needs to know to catch themselves a Mega Diancie.
How to get Diancie in Pokemon GO

Diancie is a Legendary dual-type monster with a stat spread of 190 ATK, 285 DEF, and 137 STA. The beast is vulnerable against Grass, Ground, Steel, and Water-type attacks and resistant to Dragon, Bug, Fire, Dark, Normal, and Flying-type moves. Its best moveset consists of Rock Throw and Rock Slide with a combined DPS (Damage per second) of 10.67.
Diancie makes its debut through Pokemon GO, and players who have acquired the Fest Ticket will be able to participate. Ticket-holding trainers will have access to the Special Research Task, where they can learn more about the monster and earn themselves an encounter.
The Osaka, London, and New York events had Park Adventured Special Research Task, which awarded an encounter with Diancie. Players who can catch themselves a Diancie by completing the Special Research Task can further evolve it into its Mega-form, Mega Diancie.

Mega Diancie is the evolved Mythical version of Diancie and comes with an impressive stat spread of 342 ATK, 235 DEF, and 137 STA. The monster boasts a max CP of 4913 and is vulnerable against Grass, Ground, Steel, and Water-type attacks in Pokemon GO. Mega Diancie is weak against Normal, Flying, Fire, Bug, Dark, and Dragon-type moves, while its moveset consists of Rock Throw and Moonblast (24.08 DPS).
Mega Diancie is unavailable through Raids or Special Research Tasks; however, players can evolve Diancie to get themselves a Mega. Trainers need 300 Diancie Mega Energy, which can be earned by completing a Special Research Story. Another way of acquiring Mega Energy is by winning 2-Star Carbink Raids in Pokemon GO Fest.
Can Diancie and Mega Diancie be Shiny in Pokemon GO?

Diancie and Mega Diancie debut through the Pokemon GO Fest this August. Shiny variants are always in demand in the game but are challenging to catch. Trainers must be lucky to see a Shiny; it requires passion and perseverance. As Diancie and Mega Diancie are just making their debut, their Shiny versions are unavailable. The access to Diancie is also exclusive to ticket holders to date, so one can assume Shiny Diancie and Mega Diancie will not be available for now.
