The Searching for Legends event has begun, kicking off Pokémon GO's Season of Legends! Through Sunday, March 14, 2021, at 8:00 a.m. local time, various Ground-, Rock-, and Steel-type Pokémon—like Diglett, Geodude, and Roggenrola—will be appearing more frequently in the wild. Nosepass, the Compass Pokémon, will also be appearing more frequently in the wild and in raids—and if you're lucky, you may even find a Shiny one! You can also complete event-exclusive Field Research and Timed Research to earn encounters with Nosepass, as well as other rewards.
During the event, Pokémon like Magnemite, Nosepass, Aron, Baltoy, Beldum, and Drilbur will be hatching from 5 km Eggs. You can also use Incense to attract Pokémon like Alolan Diglett, Alolan Geodude, Magnemite, Nosepass, Aron, Lairon, Beldum, Roggenrola, and Drilbur.
Pokémon like Alolan Diglett, Nosepass, Roggenrola, Drilbur, Ferroseed, and Klink will be appearing in one-star raids. And in three-star raids, you can find Pokémon like Alolan Graveler, Magneton, Skarmory, and Metang.
Good luck on your search!
