Game Freak quietly dropped a treat for Pokémon Legends Z-A players after the 1.0.2 patch landed on Nov 6, 2025. Fans booted up the game expecting bug fixes, only to find a free Diancie waiting for them through a new Extra Side Quest.

Additionally, the giveaway is the company’s teaser for the upcoming Mega Dimension DLC, which launches on Dec. 10, 2025. Because of that timing, some fans saw the quest as a preview rather than a standalone bonus.

For those who don’t know what Mega Evolution is, according to the Pokémon website, there are select Pokémon that are capable of this extra evolution ability.
“Only certain Pokémon can harness this unique skill, which changes their appearance and sometimes even their type. Mega Evolution is temporary, however, so knowing when to unleash this power is your key to victory in Pokémon battles.”

When the bond between Trainer and Pokémon is strong enough, the Key Stone resonates with the Mega Stone, allowing Mega Evolution to take place.”
After installing patch 1.0.2, players still needed to follow a few in-game steps. First, update Pokémon Legends Z-A through the Nintendo Switch 2 menu. Next, press the Y Button, go to Link Play, and pick the “Mystery Gift” option. Then select “Get Via Internet.” Finally, claim the reward titled “Shine Bright Like a Gemstone” to receive the Diancite Mega Stone.
However, getting the stone does not immediately unlock Diancie. The Mythical remains tucked behind a post-game questline. Consequently, players need both the stone and access to a specific mission linked to Emma.

Before touching the Extra Side Quest, players must finish the campaign, specifically Main Quest #37: Operation Protect Lumiose. After that, visit the Looker Bureau and interact with Emma’s Espurr. That triggers the “Shine Bright Like a Gemstone” storyline.
