The special event is available in both the base games and the downloadable expansion The Hidden Treasure of Area Zero, and runs through August 14, 2026.
Players on the Nintendo Switch can take part in new Tera Raids and Mass Outbreaks tied to the pair while the event is active.
Event overview
- Duration: through August 14, 2026 (ends at 8:59 JST, per the official Japanese announcement).
- Featured species: Glimmora (Ore Pokémon) and Glimmet (pre-evolution).
- Key activities: a Mightiest Mark Tera Raid featuring a Grass-type Glimmora and Mass Outbreaks of Glimmet with an elevated shiny encounter rate.
In an official post on the Pokémon Company’s Japanese account, the company said the special appearance of a powerful, shiny Glimmora will run until the morning of August 14, and noted that the special Mass Outbreaks increase the likelihood of encountering shiny Pokémon compared with normal play.
Put plainly, the company advised players that the limited-time outbreak windows make shiny encounters more accessible than usual for the duration of the event.
How to access the event
The in-game event content is accessible on Nintendo Switch through Pokémon Scarlet and Violet and the The Hidden Treasure of Area Zero expansion.
Players who have purchased the DLC via the Nintendo eShop can participate in the expansion’s activities as they would in the base games.
The event includes both single-instance content (the Mightiest Mark Tera Raid) and recurring Mass Outbreaks that spawn multiple Glimmet in the overworld during specified outbreak windows.
Context and developer notes
Pokémon Scarlet and Violet are the ninth-generation mainline Pokémon titles developed by Game Freak and published by The Pokémon Company and Nintendo for the Nintendo Switch; the games originally launched on November 18, 2022.
The Hidden Treasure of Area Zero expansion continues content support for the titles, and such limited-time events have become a regular way for the franchise to rotate in rare Pokémon, Tera Raid battles, and boosted shiny chances.
Players interested in participating should boot the game on their Nintendo Switch, check in-game news or the online communication features for exact outbreak times, and ensure any needed DLC is installed from the Nintendo eShop before the event closes on August 14, 2026.
